1. INTRODUCTION 

1.1 The Africa- Indian (AFI) Meteorological Bulletin Exchange (AMBEX) scheme was 

established by the AFI Planning and Implementation Regional Group (APIRG) in 1986. The scheme 

became operational in 1986 and has since then been successfully serving the ICAO AFI Region in the 

exchange of the required OPMET information. 

Note: AFI Meteorological Advisory Group ( AFMAG ) was created by the LIM AFI ( COM/MET/RAC ) RAN Meeting in 

Lome April 1988 and established by APIRG/6 Meeting in November 1989.AFMAG was replaced by AFI 

Meteorology Sub Group ( MET/SG ) at APIRG/11 Nairobi 1998. AMBEX was implemented starting on 29 August 

1986. 

1.2 AMBEX scheme was intended initially only for TAF exchanges. AIREPs and METAR were 

added to the scheme at a later stage and SIGMET, Volcanic Ash Advisory (VAA) and tropical Cyclone 

(TCA) has been added in this edition. The operation of the AMBEX scheme included exchange of 

OPMET bulletins between the originating tributary offices and the bulletin compiling centres, which, 

according to their functions and responsibilities, were classified as METAR Collection Centres, TAF 

Collection Centres and AIREP Collection Centre. The operational exchange has been carried out 

according to agreed transmission schedules; the bulletin contents were specified in the AMBEX 

Handbook. 

1.3 The procedures described hereunder are based to a significant degree on corresponding 

procedures in use in the Regional OPMET Bulletin Exchange (AMBEX) Scheme (AFI). Although 

uniformity is desired, the AMBEX Scheme is not intended as a rigid scheme for the AFI Region where 

variations or adaptation of the basic principles appear more efficient. AMBEX centre authorities are 

strongly requested to suggest to the Secretary of the MET/SG any local changes that are considered 

desirable for the enhancement of the efficiency of the scheme. 

1.4 Based on communications (COM) facilities of very limited capacity in the early seventies, the 

AMBEX scheme was strictly planned to accommodate only those OPMET exchanges considered vital for 

the flight operations. Over the years, the COM facilities have been improving considerably and the 

AMBEX scheme has been developed accordingly. 

1.5 Recently, it has been identified that significant changes in the scheme were needed in order to 

make it compatible with the existing COM environment and satisfy the evolving user requirements. In 

view of this, APIRG adopted conclusions that called for further development of the AMBEX scheme 

according to the new operational requirements. 

1.6 The AMBEX Handbook is the main guidance material providing detail on the procedures for 

OPMET exchange under the AMBEX scheme. The Handbook defines the responsibilities of the AMBEX 

centres and the procedures to be followed. It defines also the content and format of the AMBEX bulletins. 

1.7 The AMBEX Handbook is published and kept up-to-date by the ICAO ESAF and WACAF 

Offices.


2. AMBEX SCHEME - GENERAL 

2.1 Objective 

2.1.1 The main purpose of the AFI Meteorological Bulletins Exchange (AMBEX) Scheme is to: 

2.2 Structure 

• ensure the most efficient and economical exchange of operational meteorological 

(OPMET) information within the AFI Region as well as with the other ICAO regions to 

meet the requirements of users of OPMET information, and 

• ensure the implementation of the OPMET-related SARPs in Annex 3 and Annex 10, and 

the relevant provisions of the ICAO Air Navigation Plan (ANP) for the AFI Region in a 

highly efficient and standardized way. 

2.2.1 The above objective is achieved by implementing a number of AMBEX collecting and 

disseminating centres (AMBEX centres), Regional OPMET data banks (RODBs)*, and inter-regional 

OPMET gateways (IROGs). All these operational units form the AMBEX scheme. In order to ensure 

seamless global exchange of the required OPMET information, the AMBEX Scheme should be 

developed in compliance with similar structures in the other ICAO regions, as well as with the 

aeronautical fixed system (AFS) satellite distribution systems used to disseminate OPMET data. 

* Note: The AFI OPMET Regional Data BANKS are currently located in Dakar, Senegal and 

Pretoria, South Africa. 

2.3 Products 

2.3.1 The AMBEX scheme prepares and delivers to the aviation users the required OPMET 

information in the form of bulletins. The scheme should handle all types of OPMET information in 

alphanumeric bulletin form and should provide facilities and services for scheduled and non-scheduled 

delivery of OPMET information to users. 

2.4 Communications -General 

2.4.1 Use of AFS Components 

According to Annex 3, 11.2,” telecommunications facilities used for the exchange of operational 

meteorological information should be the aeronautical fixed service”. The use the AFS for the OPMET 

exchange encompass two components: 

• Use of terrestrial AFTN circuits; and 

• Use of satellite distribution systems-SADIS .


2.4.2 Use of the AFTN 

2.4.2.1 In the AMBEX scheme AFTN circuits are used for collection of the OPMET messages by the 

AMBEX centres and for regional and inter-regional exchanges of OPMET bulletins. The access to the 

regional OPMET data banks (request-reply service provided by the RODBs) is also provided through the 

AFTN. 

2.4.2.2 OPMET bulletins transmitted via the AFTN shall be in encapsulated in the text part of the 

AFTN message format ( Annex 3, Appendix 10, 2.1.4). 

2.4.2.3 Transit times of the AFTN messages and bulletins containing OPMET information are 

specified in Annex 3, Appendix 10, 1.1 

2.4.2.4 OPMET bulletins via AFTN should use the following priority indicators: 

• FF: SIGMET, AIREP SPECIAL, VAA,TCA and TAF amend ( cf. Annex 10 Vol II, 

4.4.1.1.3) 

• GG: TAF, METAR and SPECI (cf. Annex 10 VolI, 4.4.1.1.4) 

2.4.2.5 Filing times of the bulletins should be according to Annex 3, Appendix 10, 2.1.2 

2.4.3 Use of the Satellite Distribution System for aeronautical information (SADIS-operated 

by the UK) 

2.4.3.1 SADIS satellite broadcast is used by the authorized users in the States for receiving global 

OPMET DATA. 

2.4.3.2 FASID Table MET 7 of the AFI regional plans contains a list of authorized users for the 

SADIS broadcast. 

2.5 Use of the Internet 

2.5.1 Internet may be used to the dedicated internationally agreed circuits for exchange of 

meteorological data. An internet based FTP service to SADIS has been operational since 2002. 

2.5.2 In future, it is intended that RODBs should also provide internet based facilities for retrieval of 

OPMET information. RODB Dakar is already using the Internet to provide METARs and TAFs. 

2.6 Management 

2.6.1 Monitoring of the OPMET exchange under the AMBEX Scheme, planning for improvements 

and preparation of proposals for any changes that may be necessary, are carried by the APIRG. In order to 

achieve these tasks, the AMBEX implementation status and planning is part of the agenda of the AFI 

MET Sub-group MET/SG. 

Note: When necessary, contributory bodies may be established by APIRG or the MET Sub-group to 

deal with OPMET specific issues. The AFI OPMET Management Task Force, established by APIRG/16 is 

currently tasked to deal with all OPMET related issues in the AFI Region 

2.6.2 Any proposals for amendments to the AMBEX Scheme , which States or international


organizations concerned consider it necessary, due to changes in operational requirements for OPMET 

data or to developments of the AFS , should be forwarded for consideration by the ICAO Regional 

Offices of Dakar, Senegal and Nairobi, Kenya as the case my be. 

2.7 Documentation 

2.7.1 The AMBEX Handbook is the main guidance material related to the AMBEX Scheme. It should 

be kept up-to-date by the ICAO Regional offices referred to above coordinated by the Secretary of the 

OPMET Task Force in close coordination with the Secretary of the MET Sub-group. 

2.7.2 The AFI OPMET Data Banks Interface Control Document(ICD) is a supplementary document 

which provides users with guidance on the interrogation procedures and the content of the RODBs.


3. DEFINITIONS AND SYMBOLS 

3.1 Within the AMBEX Scheme, the following definitions and symbols are used: 

i) AMBEX: AFI MET Bulletins Exchange (Scheme); 

ii) AMBEX Bulletin: A collection of AMBEX messages originating from MET offices 

within a collection area, always containing the same type of OPMET data and identified 

by an appropriate identifier. Bulletins should not exceed 1800 characters in length; 

iii) National OPMET center (NOC). Normally, a NOC is associated with the State’s 

national AFTN centre/switch. The role of the NOC is to collect all OPMET messages 

generated by the originating stations in the State and to send them to the responsible 

AMBEX bulletin compiling center (AMBEX BCC). Some NOCs serve also as AMBEX 

BCCs. National regulations should be developed to ensure that NOCs disseminate the 

international OPMET data within their own State, as necessary. 

iv AMBEX Bulletin Compiling Centre (BCC): AMBEX centres (former TCC, MCC or 

ACC, etc..) are responsible for collection of OPMET messages from the originating 

stations or NOCs in their area of responsibility and for compiling these messages into 

AMBEX bulletins. FASID Tables MET 4A and MET 4B determine the areas of 

responsibility (or, collection areas) of the AMBEX centres for METAR/SPECI, and TAF, 

respectively. 

v) OPMET Inter-regional Gateway (IROG) A designated centre charged with the 

responsibility of exchanging OPMET data between stations within the AFI Region and in 

adjacent regions, as prescribed in this Handbook. The plan of OPMET data exchange 

between regions through an IROG is based on pre-determined distributions 

responsibilities, and/or on a request/reply basis; 

vi) YPYX: Fifth, sixth, seventh and eighth letter of an addressee indicator to be used: 

a) with the normal four-letter location indicators, to designate BCCs 

b) with indicators for pre-determined distribution within a BCC collection area. 

vii) Regional OPMET Data Bank (RODB): A centre charged with task to collect OPMET 

bulletins from AMBEX centres, handle all types of OPMET bulletins, provide facilities 

for “request-reply” service to authorized users, maintain a catalogue of bulletins, quality 

control the incoming bulletins and inform AMBEX centres on any deficiencies, monitor 

the OPMET traffic and report to the ICAO Regional Office on the results 

Note: The designated RODB and their responsibilities are described in Appendix E


4. OPMET INFORMATION AND OPMET EXCHANGES

4.2 OPMET bulletins 

4.2.1 The exchange of OPMET data is carried out through bulletins containing one or more 

meteorological messages (METAR, SPECI, TAF or other OPMET information). An OPMET bulletin 

contains messages of the same type. 

4.2.2 The format of OPMET bulletins is determined by: 

- ICAO Annex 10, Aeronautical telecommunications, as regards the AFTN envelope of the bulletin; 

- WMO-No.386, WMO Manual on the Global telecommunication System, as regards the WMO 

abbreviated heading of the bulletin; 

- ICAO Annex 3 and WMO-No.306, Manual on Codes, as regards the format and coding of the 

information included in the bulletin. 

4.3 Types of OPMET exchange 

4.3.1 Regional exchange – AMBEX scheme 

4.3.1.1 The AMBEX scheme covers the exchange of OPMET information in the AFI region. It 

includes several types of exchanges as described below. 

4.3.1.1.1 Regular Exchange under AMBEX. This is a scheduled exchange that encompasses 

collection of messages from the originating stations, compiling of bulletins and their dissemination 

according to predetermined distribution schemes. The collection and distribution is carried out at fixed 

times and the bulletin content is defined in the current Handbook.

4.3.1.1.2 Non-regular exchange. This includes: 

a) Exchange on request (request-reply service). The RODBs store OPMET data and make them 

available on request. 

b) Exchange of non-routine reports: SPECI; TAF AMD; SIGMET; TCA and VAA; ADMIN 

messages.; 

4.3.2 Inter-regional OPMET exchange 

4.3.2.1 Exchange of OPMET data between the AFI and the other ICAO Regions is carried out via 

designated centres, which serve as Inter-regional OPMET Gateways (IROG). An IROG is set up for 

sending/receiving specified OPMET data between AFI and every other ICAO region for which AFI 

OPMET data are required. 

Note: The former name of these centres is ODREP. 

4.3.2.2 Inter-regional OPMET exchange via IROGs is carried out through the ground segment of 

the AFS (currently, through the AFTN). 

4.3.3 Exchange of OPMET information through the satellite segment of the AFS 

4.3.3.1 The three satellite broadcasts provided by the United Kingdom (Satellite Distribution 

System for Aeronautical Information Relating to Air Navigation - SADIS) and the United States 

(International Satellite Communication System – ISCS/1 and ISCS/2), form another type of OPMET 

exchange, which is global in nature and is intended to cover the emerging requirement for global access 

to all available OPMET data. 

4.3.3.2 All AFI data handled by the AMBEX scheme should be relayed to the SADIS for global 

broadcast. 

4.3.4 Other OPMET exchanges 

4.3.4.1 Where OPMET exchanges described in the above paragraphs are not sufficient, direct 

AFTN addressing should be utilized by the originating centres.


5 COMPOSITION OF AMBEX 

5.1 Components of the AMBEX 

5.1.1 AMBEX scheme involves a number of aeronautical meteorological stations, aeronautical 

telecommunication stations, aerodrome meteorological offices and other operational units. The following 

operational units should be considered as components of the AMBEX scheme: 

- Originating station 

- National OPMET center (NOC) 

- AMBEX bulletin compiling centre (BCC)-AMBEX Centre 

- Regional OPMET Data Banks (RODBs) 

- Interregional OPMET gateway (IROG) . 

5.2 Originating Station 

5.2.1 It is an aeronautical meteorological station or an aerodrome meteorological office, or a 

forecasting office, or a MWO, or a TCAC, or a VAAC. The duties and responsibilities of these 

originating stations should be defined by the State’s meteorological authority. 

5.3 National OPMET Center (NOC). 

5.3.1 Normally, a NOC is associated with the State’s national AFTN centre/switch. The role of 

the NOC is to collect all OPMET messages generated by the originating stations in the State and to send 

them to the responsible AMBEX bulletin compiling center (AMBEX BCC). Some NOCs serve also as 

AMBEX BCCs. National regulations should be developed to ensure that NOCs disseminate the 

international OPMET data within their own State, as necessary. 

5.4 AMBEX Bulletin Compiling Centre (AMBEX BCC or, in brief, AMBEX centre). 

5.4.1 AMBEX centres are responsible for collection of OPMET messages from the originating 

stations or NOCs in their area of responsibility and for compiling these messages into AMBEX bulletins. 

FASID Tables MET 4A and MET 4B determine the areas of responsibility (or, collection areas) of the 

AMBEX centres for METAR/SPECI and AIREP SPECIAL, and TAF, respectively. 

5.4.2 The AMBEX centres are responsible for the transmission of the bulletins compiled by 

them to: 

- other AMBEX centres, according to predefined distribution lists, specific for each bulletin; 

- AFI RODBs (Dakar and Pretoria); 

- NOCs or other COM or MET offices in the States in their area of responsibilities, as agreed 

between the AMBEX centre and the States’ authorities concerned. 

Note: The former AMBEX scheme involved separate compiling centres for METAR and TAF (METAR 

Collection Centres, and TAF Collection Centres. In some cases, METAR from an aerodrome was 

compiled by one center, and the TAF from another center. The evolution of AMBEX should be towards 

unified AMBEX centers responsible for collecting/distributing of all OPMET data types within their area 

of responsibility.


5.5 Regional OPMET Data Banks (RODB) 

5.5.1 Two centres have been designated by APIRG (APIRG/13 Conclusion 13/67, 2001), to 

serve as Regional OPMET Data Banks: Dakar and Pretoria. FASID Table MET 4C reflects the 

requirements for the operation of the AFI OPMET data banks to support the AMBEX Scheme. 

5.5.2 The main responsibilities of the RODBs are defined, as follows: 

- to support the AMBEX Scheme and to facilitate a regular exchange of OPMET information based 

on predetermined distribution within the AFI Region; 

- to operate as Inter-regional OPMET Gateway (IROG) with responsibility of exchanging OPMET 

information between AFI Region and the adjacent Regions; and 

- to provide facilities for request/response type of access to the stored OPMET data for users to 

obtain non-regular or occasional information. 

Note. — The interrogation procedures applicable to the OPMET data banks and catalogues are provided 

in the “AFI Regional Interface Control Document (ICD) - OPMET Data Bank Access Procedures”, 

published and maintained by the ICAO Regional Offices in Dakar and Nairobi 

5.6 Inter-regional OPMET Gateways (IROG). 

5.6.1 The Inter-regional OPMET Gateways in the AFI Region are the designated RODBs. Each 

RODB is assigned responsibility for exchange of OPMET information with other ICAO Regions. The 

responsibilities of the IROGs for AFI is shown in para. 11.1 of this Handbook. 

5.6.2 Support to the SADIS broadcast. The RODBs and IROGs should facilitate the global 

exchange of OPMET data carried out through the SADIS satellite broadcast. In order to achieve this, 

close liaison should be maintained between the IROGs and the corresponding SADIS gateways. 

Availability of AFI data on SADIS should be monitored and any systematic shortfalls of data identified 

should be reported to the relevant ICAO regional office.

6. TAF EXCHANGE 

6.1 General 

6.1.1 Aerodrome forecast (TAF) should be prepared by the aerodrome meteorological offices 

(AMOs) or other meteorological offices, designated for provision of TAF by the State’s meteorological 

authority, for all international aerodromes, for which TAF is required according to FASID Table MET 1A 

of the AFI ANP. 

6.1.2 All TAFs required should be included in the regular AMBEX exchange. In addition, TAFs 

from a number of other, including domestic aerodromes, required by the users, should also be included in 

the regular AMBEX exchange, if so agreed by the States concerned. 

Notes: 1) The recent requirement by airlines is that TAF for all international aerodromes 

listed in AFI FASID Table MET 1A should be available through regular exchange 

and through the satellite distribution system SADIS.. 

2) SADIS User Guide (SUG) Annex 1 presents the requirements for OPMET data 

(METAR and TAF) by aviation users. When OPMET data from domestic airports 

(so called non-AOP airports) is required by users, the corresponding State is 

consulted on its agreement for providing this additional information. If the 

information is available and the State agrees to include it in the exchange, the 

additional airports are included in SUG Annex 1 and the State should provide the 

additional OPMET information on a continuous basis. 

6.1.3 TAF exchanges not covered by the AMBEX Scheme, but required operationally, should be 

met by means of direct addressed AFTN messages. 

6.1.4 The requirements for the exchange of 24 or 30-hour TAFs (so called “long” TAFs with 

WMO data designator – FT), are set in FASID Table MET 1A of the ANP. “Short” TAFs with 9- or 12hour 

period of validity (WMO data designator - FC), are no longer issued by States in the AFI region 

6.1.5 AMBEX messages and bulletins are normally sent via the AFTN. In exceptional 

circumstances, when the AFTN cannot give adequate support to AMBEX traffic, the temporary use of 

alternative existing communications systems should as far as possible be coordinated with the ICAO 

Regional Offices concerned. 

6.1.6 Each AMBEX message and AMBEX bulletin should conform strictly to the Annex 10 

message format. 

6.1.7 Each AMBEX message and AMBEX bulletin should carry a WMO abbreviated heading 

(see Appendix C). 

6.1.8 Each AMBEX message or bulletin, should terminate with an equal (=) sign (signal no. 22 

of International Telegraph Alphabet no.2 in the figure case). 

6.1.9 The procedures described in this Handbook are intended for the manual preparation of 

AMBEX messages and bulletins. It is not intended, however, that the Handbook precludes the use of 

automated or semi-automated procedures. When required, the procedures described hereunder should be 

modified and applied in a manner which will fully exploit the capabilities of the equipment available. The 

AMBEX messages and bulletins produced by application of such modified procedures should be in a


format compatible with the format described in this Handbook. 

6.2 Responsibilities and procedures to be followed by originating aerodrome 

meteorological offices (AMOs) and NOCs 

6.2.1 Originating AMOs (or other designated forecasting offices) should prepare the required 

TAF messages for the periods of validity indicated in Appendix B. TAFs should be sent by the AMOs or 

NOCs and to the responsible AMBEX center before the cut-off time set up by this centre. 

6.2.2 Aerodrome meteorological offices in preparing TAF should follow strictly the template for 

TAF in Annex 3, Appendix 5 and the WMO TAF code form (FM 51-XII TAF, WMO – No. 306, Manual 

on Codes, Volume I.1, Part A – Alphanumeric Codes). 

6.2.3 TAFs should be monitored by the originating AMOs and amended TAF (TAF AMD) 

should be issued according to the established criteria. Amended TAFs should be sent by the originating 

station to the responsible AMBEX centre with no delay. The optional group BBB should be used in the 

WMO abbreviated heading to indicate amended TAF in accordance with Appendix C. 

6.2.4 TAF messages should be quality controlled by the originating meteorological offices and, 

when necessary, a corrected TAF (TAF COR) should be sent immediately after an error in an already 

transmitted message had been identified. 

6.2.5 Within five minutes of the time of preparation of the TAFs, an AMBEX message should 

be filed for transmission to the BCC concerned. 

6.2.6 Not later than five minutes after being filed for transmission, the AMBEX messages 

should be sent to the BCCs. This means that BCCs should have available AMBEX messages from all 

stations in their area of responsibility (AOR) within ten minutes of the times shown in column 6 of 

Appendix B. 

6.2.7 The following is an outline of the procedures to be applied in preparing an AMBEX 

message at an office other than a BCC:

e) Normal Ending.


6.2.8 If an amendment to a TAF previously issued becomes necessary, a new AMBEX 

message should be prepared and sent to the BCC concerned. The WMO abbreviated heading for this 

message should be the same as for the AMBEX message containing the original TAF, with the addition 

of the optional groups AAA, AAB, AAC etc. (to indicate the first, second, third etc. amendment to the 

original TAF). Optional groups are also used for sending delayed TAFs, RRA, RRB, RRC, etc and 

corrected TAFs CCA, CCB, CCC, etc in accordance with Appendix C. 

6.2.9 TAFs for individual aerodromes in the AMBEX Scheme should not be addressed to 

aerodromes in those cases where the AMBEX Scheme already caters reliably for their dissemination. 

6.2.10 Requests for missing bulletins should be sent to the BCC responsible for compiling the 

bulletins and should be in the following format:

d) Normal ending NNNN. 

Note: Certain BCCs may require AFTN addresses other than those of the BCCs 

themselves to be used for request messages. A list of such addresses will be 

compiled and included in the AMBEX Handbook. 

6.2.11 Provisions concerning request messages to the AFI RODBs are given in the ICD of the 

Dakar and Pretoria RODBs. 

6.3 Responsibilities and procedures to be followed the AMBEX Centres (BCCs) 

6.3.1 AMBEX centres should collect TAFs from the AMOs and/or NOCs in their area of 

responsibility and compile TAF Bulletins according to Appendix B. The areas of responsibility, as far as 

practicable, should group together aerodromes and their alternates. AMBEX centres should ensure that 

TAFs within their area of responsibility have common periods of validity. 

6.3.2 AMBEX centres should establish a cut-off time for reception of TAFs from AMOs and/or 

NOCs in their area of responsibility, e.g., 15 minutes before the filing/transmission times specified in 

Appendix B. At the cut-of time AMBEX centres should compile TAF bulletin(s) containing all 

prescribed aerodromes, without indicating any missing TAF with “NIL”. 

6.3.3 The filing time for 24- and 30-hour TAF bulletins should be two hours before the start of 

the validity period. 

6.3.4 AMBEX centres should transmit the compiled TAF bulletins to other AMBEX centres and 

the RODBs according to the distribution lists as specified for each TAF bulletin in Appendix B.


6.3.5 AMBEX centres should transmit the TAF bulletins compiled by them, as well as TAF 

bulletins received from other AMBEX centres, as necessary, to the NOCs and/or other offices in the 

States in their area of responsibility, as agreed between the AMBEX centre and the meteorological 

authorities of the States concerned. 

6.3.6 A TAF message received by a AMBEX centre after the scheduled transmission of the 

corresponding bulletin is a delayed TAF. The AMBEX centre should then prepare an AMBEX bulletin of 

all TAFs received. If a TAF is not available, for any reason, at the cut-off time, the latest still valid TAF 

for the missing station may be included instead. 

6.3.7 Amended TAF (TAF AMD) received from an AMO or NOC should be distributed with no 

delay as an amended TAF bulletin to all recipients in the distribution list for the TAF bulletin, to which 

the originating aerodrome belongs. The optional BBB group should be used in the WMO bulletin heading 

accordingly. 

6.3.8 Each BCC should establish a cut-off time for the reception of AMBEX messages from 

stations within its AOR. The cut-off time should be about twenty minutes after the times of preparation 

of TAFs shown in column 6 of Appendix B. 

6.3.9 A new tape, containing the address, origin and WMO abbreviated heading of the bulletin, 

is prepared. The bulletin is then assembled by combining this new tape with the text portions of the 

AMBEX messages received and adding a normal ending. Details of the WMO abbreviated headings that 

should be used by BCCs in their bulletins are given in Appendix C. 

6.3.10 AMBEX centres should disseminate their own bulletins to the stations listed in column 9 

of Appendix B. This dissemination should take place some thirty minutes after the time for preparation 

of the TAFs shown in column 6 of Appendix B. 

6.3.11 No addresses other than those listed in column 10 of Appendix B should be used except 

in response to request messages. 

6.3.12 The following is an outline of the procedures to be followed by AMBEX centres in the 

preparation of AMBEX bulletins.

6.3.13 TAFs received by an AMBEX Centre after the cut-off time, and which have still at least 6hour 

validity left, should be included in one or more bulletins of delayed TAFs. The WMO Abbreviated 

Heading for such bulletins should be the same as for the bulletin from which the TAFs are missing, with 

the addition of the optional groups RRA, RRB, RRC etc. (to indicate the first, second, third etc. bulletin 

of delayed TAFs), in accordance with Appendix C, paragraph 4. 

6.3.14 When an AMBEX centre receives amended TAFs from originating stations or NOCs, it 

should prepare bulletins of amended TAFs. The WMO abbreviated heading for such bulletins should be 

the same as for the bulletin containing the original TAF, with the addition of the optional groups AAA, 

AAB, AAC etc. (to indicate the first, second, third etc. amendment to TAFs in the original bulletin), in 

accordance with Appendix C, paragraph 4. 

6.3.15 "NIL" to indicate a missing TAF should not be used in AMBEX bulletins. 

6.3.16 If an AMBEX centre finds it impossible to meet the specified filing times due to systematic late 

receipt of TAFs from originating stations or NOCs, it should reach an agreement with these stations on 

another filing time for their AMBEX messages and thereafter propose to the Secretary of the AFI 

MET/SG that this filing time be incorporated in the Handbook. 

6.3.17 In addition to its own AMBEX bulletins, each BCC should distribute bulletins received from 

other BCCs to the MET offices within its originating stations or NOCs. 

6.4 Format and content of TAF bulletins 

6.4.1 Issuance and period of validity:


6.4.1.1 24- and 30-hour TAFs should be issued at intervals of six hours, with the period of validity 

beginning at one of the main synoptic hours (00, 06, 12, 18 UTC), as shown in the table below.

*Note: “-1” indicates the previous day and “+1” indicates the next day 

6.4.1.2 All TAFs in a AMBEX TAF bulletin should have a common period of validity. It is not 

allowed to mix “long” and “short” TAFs in one bulletin. 

6.4.2 Each TAF message in a TAF bulletin should start with the code word TAF followed by the 

ICAO location indicator (CCCC) of the aerodrome and the date/time group (YYGGggZ), indicating the 

official time of issuance. Corrected TAF messages, should start with TAF COR. Amended forecasts 

should start with TAF AMD. 

6.4.3 The use of the BBB group in the WMO heading for delayed, corrected, or amended TAFs 

is described in Appendix C. 

6.4.4 The following is an outline of the format to be applied by a AMBEX centre in preparing a

7. SPECIAL AIREP EXCHANGE 

7.1 The meteorological watch offices (MWO) are responsible for collection through their 

associated ATS units of special air reports (AIREP SPECIAL) received from aircrafts within their FIR or 

CTA. 

Note: – Routine air-reports received by data-link communications should be relayed directly to the 

WAFCS by the ATS unit. 

7.2 MWOs should collect all special air-reports and prepare one-hour collectives in the form 

of a UA bulletin for transmission to the responsible AMBEX centre at the time specified by the AMBEX 

centre. 

Notes: 1) The transmission of air-reports to the WAFCs as required by Annex 3 should be 

arranged by the meteorological authorities concerned. 

2) MWOs should follow the special requirements for the dissemination of special airreports 

as defined by Annex 3, 

7.3 AFI FASID Table 2B describes the exchange of SIGMET and special AIREP reports 

procedures.


8. METAR/SPECI EXCHANGE 

8.1 General 

8.1.1 Hourly METAR reports should be prepared by all international aerodromes listed in 

FASID Table MET 1A. METAR should be issued on an hour intervals for those aerodromes, included 

in the HF VOLMET broadcasts (cf. FASID Table ATS 2 – HF Radiotelephony VOLMET Broadcasts), or 

D-VOLMET. 

8.1.2 METAR from all international aerodromes listed in Table AOP 1 of the Basic ANP and , 

in FASID Table MET 1A, should be included in the regular AMBEX exchange. In addition, METAR 

from a number of domestic aerodromes, required by the users, should also be included in the regular 

AMBEX exchange in accordance with para. 12.1.3, if so agreed by the States concerned. 

Note: SADIS User Guide (SUG) Annex 1 presents the requirements for OPMET data (METAR 

and TAF) by aviation users. When OPMET data from domestic airports (so called non- 

AOP airports) is required by users, the corresponding State is consulted on its agreement 

for providing this additional information. If the information is available and the State 

agrees to include it in the exchange, the additional airports are included in SUG Annex 1 

and the State should provide the additional OPMET information on a continuous basis. 

8.1.3 Description of the AFI METAR bulletins included in the regular AMBEX exchange, 

containing the responsible compiling AMBEX centre, WMO bulletin identification, and the list of 

aerodromes included in the bulletin, is given in Appendix A. 

8.1.4 The official hour of observation to be included in the METAR bulletin heading is indicated 

in the table in Appendix A. 

8.1.5 All METAR bulletins should be sent to both RODBs Dakar and Pretoria. AMBEX centres 

should exchange METAR bulletins according to the distribution lists given in Appendix A. 

7.1.6 SPECI reports should be disseminated in the same way as the METAR reports originated 

by the same aerodrome. 

8.1.7 Exchange of METAR/SPECI messages outside AMBEX scheme, if necessary should be 

carried out by direct AFTN addressed messages. 

8.2 Responsibilities of originating stations and NOCs 

8.2.1 The originating stations (aeronautical meteorological stations) and/or NOCs should 

prepare METAR messages for the observation times indicated in Appendix A and send them to their 

responsible AMBEX center. 

8.2.2 SPECI should be prepared between the regular observation times, following the 

requirements set in Annex 3 and sent with no delay to the responsible AMBEX centre. 

8.2.3 In preparing METAR and SPECI messages the originating stations should follow strictly 

the specifications for METAR and SPECI in Annex 3 (Chapter 4 and Appendix 3 including the template 

in Table A3-2) and the WMO METAR and SPECI code forms (FM 15-XII METAR and FM 16-XII 

SPECI, WMO – No. 306, Manual on Codes, Volume I.1, Part A – Alphanumeric Codes).


8.2.4 METAR messages should be sent to the responsible AMBEX centre before the cut-off 

time specified by the AMBEX centre, to allow for timely compilation of the METAR bulletin. If, for 

some reason, a METAR message has not been sent before the cut-off time, the originating station/NOC 

should send it as soon as possible after that, as a delayed message. The originating stations/NOCs should 

follow strictly the schedules specified for METAR messages and keep to a minimum the number of 

delayed messages. 

8.2.5 METAR and SPECI messages should be quality controlled by the originating 

stations/NOCs and, when necessary, a corrected message should be sent immediately after an error in an 

already transmitted message had been identified. 

Note: Procedures applying to the corrected and delayed messages are given in Appendix C. 

8.3 Responsibilities of AMBEX Centres 

8.3.1 AMBEX centres should collect METAR messages from the aerodromes in their area of 

responsibility and compile METAR bulletins, according to Appendix A. The content of bulletins and the 

order of stations in each bulletin should be kept fixed until a bulletin change is requested and coordinated 

according to the established procedure. 

8.3.2 AMBEX centers should determine a cut-off time for the reception of METAR from the 

stations in their area of responsibility. At the cut-off time, the AMBEX centre should compile METAR 

bulletin(s) containing all prescribed aerodromes, indicating any missing METAR with “NIL”. 

8.3.3 At scheduled transmission times AMBEX centres should transmit the compiled METAR 

bulletins to other AMBEX centres and RODBs according to the distribution lists specified for each 

METAR bulletin in Appendix A. METAR bulletins should be filed for transmission not later than 5 

minutes after the observation time. 

8.3.4 AMBEX centres should transmit the METAR bulletins compiled by them, as well as 

bulletins received from other AMBEX centres, as necessary, to the NOCs and/or other offices in the 

States in their area of responsibility, as agreed between the AMBEX centre and the meteorological 

authorities of the States concerned. 

8.3.5 A SPECI when received by an AMBEX centre should be sent as a SPECI bulletin to the 

same addresses, to which METAR from the issuing aerodrome are sent. Normally, a SPECI bulletin 

should contain a single SPECI. 

8.3.6 The WMO heading of a SPECI bulletin should be constructed in the same way as the 

WMO heading of the METAR bulletin, which contains the aerodrome, for which the SPECI is issued, by 

using SP data type designator instead of SA. 

8.3.7 A METAR message received by the AMBEX centre after the scheduled transmission of 

the corresponding bulletin is a delayed METAR. The AMBEX centre should send a delayed bulletin as 

soon as one or more delayed messages are received or at specified times after the scheduled bulletin time 

(e.g., the first delayed bulletin (RRA) issued 10 minutes after the regular time; the second delayed bulletin 

(RRB) issued 20 minutes after the regular time, etc.). 

8.3.8 As soon as a corrected METAR or SPECI message is received from a station the AMBEX 

centre should transmit it as a corrected bulletin to all recipients.


8.4 Format and content of METAR Bulletins 

8.4.1 Each METAR message in a METAR bulletin should start with the code word METAR 

followed by the ICAO location indicator (CCCC) of the aerodrome and the date/time group (YYGGggZ), 

indicating the official time of observation. Corrected METAR messages, should start with METAR COR. 

8.4.2 The following is an example of the format to be applied in preparing a METAR bulletin by 

the AMBEX centre:

compulsory. 

8.4.3 The rules related to the use of the BBB group in the WMO abbreviated heading, in regard 

to delayed or corrected bulletins, are given in Appendix C. 

8.4.4 For METARs, which are not available at the time of compilation of the bulletin, the code 

word NIL should be inserted following the date/time group indicating the time of the observation. 

Example: METAR ZBTJ 271200Z NIL= 

8.5 Format and content of SPECI Bulletins 

8.5.1 A SPECI message included in a SPECI bulletin should start with the code word SPECI 

followed by the ICAO location indicator (CCCC) of the aerodrome and a date/time group (YYGGggZ) 

indicating the time of the observation of the meteorological conditions for which the SPECI is issued. 

Corrected SPECI messages, should start with SPECI COR. The following is an example of the format to 

be applied in preparing a SPECI bulletin by the AMBEX centre:

9. EXCHANGE OF SIGMET AND ADVISORIES 

9.1 SIGMET should be prepared by the meteorological watch offices (MWO) designated by 

the State’s meteorological authority. The MWOs and their areas of responsibility are given in the FASID 

Table MET 1B of AFI ANP. 

9.2 SIGMET should be distributed to the two RODBs, either directly or through the 

responsible AMBEX centre. The RODBs should make SIGMET messages available on request. In order 

to facilitate that, the originating MWOs, should use fixed WMO headings for their SIGMET bulletins as 

given in Appendix E. 

9.3 SIGMET messages should be distributed to other ICAO regions and made available for 

uplink through SADIS. This distribution should be carried out through the relevant Inter-regional 

OPMET Gateways (IROGs). 

9.4 Detailed information on the format of the SIGMET messages is provided in the AFI 

Regional SIGMET Guide, 9 th edition, Amendment 2, June 2011, at the Web page 

http://www.icao.int/wacaf/edocs/WACAF_Regional_SIGMET_Guide_en.pdf 

9.5 Tropical Cyclone Advisories (TCAs) and volcanic ash advisories (VAAs) should be issued 

by the designated tropical cyclone and volcanic ash advisory centres (TCAC and VAAC), as indicated in 

the FASID Table MET 3A and MET 3B. 

9.6 The TCACs and VAACs should send the advisories to the RODBs. The RODBs should 

make TCAs and VAAs messages available as appropriate or on request. In order to facilitate that, the 

originating TCACs and VAACs should use fixed WMO headings for their TCA and VAA bulletins as 

given in Appendix E 

9.7 VAA and TCA messages should be distributed to other ICAO regions and made available 

for uplink through SADIS. This distribution should be carried out either directly by the VAACs and 

TCACs or through the relevant Inter-regional OPMET Gateway (IROG) such as Toulouse, France.

10.2.4 Maintain a catalogue of bulletins and introduce changes to the bulletins when necessary 

according to the established procedures. 

10.2.5 Quality control the incoming bulletins and inform the AMBEX centres of any 

discrepancies or shortfalls. 

10.2.6 Monitor the OPMET traffic by carrying out regular tests on the availability and timeliness 

of the bulletins; report to the ICAO Regional Office on the results. 

10.3 The interrogation procedures applicable to the designated RODBs and the OPMET 

information stored are presented in the AFI Regional Interface Control Document (ICD) - OPMET Data 

Bank Access Procedures. 

10.4 Guidance on the management and quality control is provided in chapter 12 of this 

Handbook.


11. INTER-REGIONAL OPMET EXCHANGE - IROG FUNCTIONS 

11.1 Inter-regional OPMET Gateways (IROGs) are designated in the AFI Region for the the 

purpose of exchanging OPMET data between the AFI and the other ICAO Regions, as shown in the table 

below. 

AMBEX IROG For Excchange of OPMET data between Regions 

Dakar AFI and EUR; SAM, NAM, CAR; MID, ASIA/PAC as backup to Pretoria 

Pretoria AFI and MID; ASIA/PAC, EUR; SAM, NAM, CAR as backup to Dakar 

11.2 IROGs and their functions are described at Appendix D. IROGs arrange for relaying all 

AMBEX bulletins to a corresponding OPMET Gateway in the other ICAO regions concerned. In 

particular: 

• Dakar IROG relays all AFI bulletins to ROC Toulouse in the EUR Region, which serves the 

EUR, SAM, NAM and CAR Regions, and should receive and store all required OPMET bulletins 

from these Regions; 

• Pretoria IROG relays all AFI bulletins to ROC Toulouse in the EUR Region and IROG Bangkok 

in the the ASI/PAC Regions, and should receive and store all required OPMET bulletins from 

MID, ASIA/PAC, EUR, SAM Regions; 

11.3 The following principles are applied to IROGs: 

a) IROGs should have reliable and efficient AFTN connection to the regions, for which they have 

exchange responsibilities, with adequate capacity to handle the OPMET data flow between the 

regions; 

b) IROGs should be associated with AFTN relay centres capable of handling efficiently the volume 

of traffic anticipated; 

c) IROGs should be capable of handling all OPMET data types, as described in para.4.1.1. 

11.4 In order to avoid duplication of the OPMET traffic and information, all inter-regional 

OPMET exchange should be directed through the IROGs. Inter-regional exchange via direct AFTN 

addressing from the originator or AMBEX centre to recipients in the other ICAO Regions should be 

avoided, except when bilateral or other agreements require such direct exchanges. 

12. MANAGEMENT OF OPMET EXCHANGE UNDER THE AMBEX SCHEME 

12.1 OPMET Bulletins Update Procedure 

12.1.1 Information for changes of AMBEX bulletins should be disseminated to all AMBEX 

centres and national OPMET centres (NOC) concerned well in advance in order to allow the centres to 

introduce the necessary changes to their message handling systems. In this regard, a lead time period of 

two months (or two AIRAC cycles) is considered appropriate. 

12.1.2 The AMBEX centre planning the change, should send a notification by e-mail or fax to the 

ICAO Office, Dakar or Nairobi with copy to all AMBEX Focal Points. The notification should include


detailed information of the changes and the proposed time schedule. The Regional Office should inform 

all other ICAO Regional Offices of the changes to be introduced and the effective date of implementation. 

12.1.3 All requests by users for changes to AMBEX bulletins should be addressed to the ICAO 

Regional Office concerned. The Regional Office should carry out the necessary coordination with the 

Sates and AMBEX centres concerned. The duration of the coordination process should be minimized so 

that the period between the user request and the implementation of the change (if agreed) should normally 

be less than 3 months. 

12.2 Quality Management of OPMET Exchange under the AMBEX Scheme 

12.2.1 Objectives and Scope 

12.2.1.1 Objectives: Develop a management system that provides general guidance on procedures 

applied to OPMET exchange, which includes quality control aspects and introduces a non-real-time 

monitoring for OPMET exchange. 

12.2.1.2 Scope: Management of OPMET data exchange will be organized in the following 

sections: 

Quality Control Data quality control applies to OPMET validation and correction during data 

processing and during preparation of messages 

OPMET Monitor and evaluate the performance indicators for the scheduled OPMET data 

monitoring 

12.2.2 Quality Control – General Requirements 

12.2.2.1 Quality control (QC) consists of examination of OPMET data at NOCs, AMBEX Centres 

and RODBs to check the messages for formatting and coding errors, as well as, for time and space 

consistency. 

12.2.2.2 OPMET data should be checked in real time or as close to it as possible, at the first point, 

i.e., the originator, which may be: meteorological station, aerodrome meteorological office or 

meteorological watch office. Errors may occur during coding or transcription of meteorological messages 

by the observer or forecaster. The originating office should apply quality control procedures during data 

processing and preparation of messages, in order to eliminate the main sources of errors. 

12.2.2.3 The national OPMET centre (NOC) should apply QC procedures on the incoming 

messages from national sources and on the compiled national bulletins. 

12.2.2.4 It is also advisable to apply QC checks at the AMBEX Centre, where the AMBEX 

bulletins are received or compiled. If automation is available it should be used, or partly assisted by 

computing facilities. The principle is that every message should be checked, preferably at the various 

points along the data chain. 

12.2.2.5 The checks that have already been performed by originating offices and AMBEX Centres 

are usually repeated at the OPMET data banks. Erroneous messages found by the RODB should be either 

rejected or corrected by reference back to the source or by the data bank itself. Data corrected by the data 

banks should be flagged in the database for record purpose. 

12.2.2.6 As a result of the quality control process described above, OPMET data of established 

quality will be used in the exchange and stored in the data banks. The RODBs should compile


information with regard to errors that were found and compile records, such as the numbers and types of 

errors detected during quality control. Such non-conformities should be reported to ICAO Regional 

Office, Dakar or Nairobi for follow-up action. 

12.2.3 Quality Control Procedures 

12.2.3.1 General guidance on the quality control procedures for each type of OPMET is outlined in 

Appendix F. 

12.3 OPMET Monitoring 

12.3.1 Monitoring of Scheduled OPMET Data 

12.3.1.1 The monitoring shall focus on the measurement of three performance indicators (PIs), viz., 

Compliance, Availability and Regularity indices of the scheduled, routine OPMET data (SA, FT, FC) 

exchanged in the region. The PIs are described in detail in Appendix F. 

12.3.1.2 Monitoring Reference. The monitoring shall involve the recording and analysis of data 

provided by the AFTN circuit. The three PIs should be monitored against the respective AMBEX Tables. 

12.3.1.3 Methodology: Data is monitored with reference to the procedures defined in AppendixG 

the EUR OPMET Data Monitoring Procedures as produced by APIRG MET/SG (Bulletin Management 

Group). 

12.3.2 Monitoring of Non-Scheduled OPMET data 

12.3.2.1 Monitoring of non-routine OPMET data shall be executed for FK, FV, WC, WS, and WV. 

12.3.2.2 Monitoring of SIGMET, VAA and TCA should be performed during the scheduled 

regional SIGMET tests in accordance with the procedures published by the Regional Offices, Dakar and 

Nairobi. 

12.3.2.3 The monitoring results shall be presented in bulletin-oriented format, one line per bulletin 

indicating the abbreviated header (TTAAii CCCC YGGgg), the FIR/UIR where applicable, receipt time 

and originator. 

12.4 AMBEX Focal Points 

12.4.1 In order to facilitate exchange of information between the AMBEX centres a system of 

AMBEX focal points have been developed. Contact details of the persons designated as AMBEX focal 

points by the relevant State’s authorities is provided in Appendix I.

Manual on the Global Telecommunication System, Part II – Operational Procedures for the GTS, 

Attachment II-5, Table C1. The following principles shall apply: 

a) For AMBEX bulletins containing OPMET data from a single State or territory, the AA 

designator should be chosen from Table C1, Part I – Country or territory designators; 

b) For AMBEX bulletins containing OPMET data from more than one State or territory, a 

suitable AA designator should be chosen from Table C1, Part II – Area Designators; 

c) The part of the Table C1, Part II – Area Designators, which is relevant to the AMBEX 

scheme is reproduced bellow. 

2.1.3 In AMBEX messages prepared by offices other than BCCs for transmission to BCCs, the 

following geographical designators should be used:

2.1.4 In bulletins prepared by BCCs, the following geographical designators should be used: 

BCC AA BCC AA 

Addis Ababa EA Casablanca MC 

Alger AF Dakar AO 

Antananarivo IO Johannesburg AP 

Brazzaville AM Nairobi EA 

Cairo AF Niamey AO 

2.1.5 ii Number used to differentiate two or more bulletins which contain data in the same 

code and which originate from the same geographical area and from the same originating centre. It shall 

be a number with a maximum of two digits. The IROGs may use numbers 36 to 38. The numbers 31 to 

35, 39 shall be used in AMBEX bulletins for purposes other than those of IROGfunctions. . 

2.2 CCCC: ICAO location indicator of location preparing the AMBEX bulletin (BCCs) or 

AMBEX messages (offices other than BCCs). 

2.3. YYGGgg: Date-time group. To be used as follows: 

2.3.1 YY - Day of the month 

2.3.2 GGgg - hours and minutes. 

• For METAR bulletins/messages: the standard time of observation in UTC. 

• For TAF bulletins: the full hour in UTC (the last two digits shall be 00) preceding the 

transmission time. 

• For all other bulletin/messages - the time of compilation in UTC. 

2.4. BBB - Optional group indicating an amended, corrected or delayed bulletin. 

2.4.1 An abbreviated heading defined by TTAAii CCCC YYGGgg shall be used only once. 

Consequently, if this abbreviated heading has to be used again for an addition, a correction or an 

amendment, it shall be mandatory to add an appropriate BBB indicator, which shall be added after the 

date-time group. The indicator BBB shall be used as defined below: 

- RRx – for delayed routine meteorological messages/bulletins; 

- CCx – for corrections to previously relayed messages/bulletins; 

- AAx – for amendments to TAF messages/bulletins; 

- Pxx – for segmenting a large set of information into several bulletins. 

Note 1: The “x” above is an alphabetic character of A through X, indicating the sequential 

number of the irregular bulletin of certain type. For instance, for amended TAFs, AAA is 

used for the first amendment, AAB for the second, AAC for the third, etc; for delayed 

METARs or TAFs, RRA is used for the first delayed message, RRB for the second, etc.; 

and, for corrections to any OPMET bulletin, CCA is used for the first correction, CCB for 

the second, etc. 

Note 2: The use of the third letter A, B, C, etc. permits differentiation between bulletins/messages


with the same type of information of the original bulletin/message. For example, assuming 

that a certain bulletin had the following abbreviated heading: "FTA031 DIAP 281000", a 

delayed bulletin containing TAF(s) which are missing from the original bulletin will bear 

the heading: "FTA033 DRRN 281000 RRA"; and a second delayed bulletin, containing 

additional missing TAF(s) will bear the heading: "FTA031 DIAP 281000 RRB".

Monitoring 

2.1.1 Performance Indicators (PIs). The indices to be used by the RODBs are based on those 

developed by the European BMG for monitoring the SADIS distribution (ref. SADISOPSG/8, IP/5 – 

SADIS OPMET Performance Indices). 

(i) Compliance Index 

The AMBEX Compliance index can be calculated from:


Vbul compliance = 

The Compliance Index is to assess the level of compliance to the AMBEX scheme. The determination of 

the compliance index is performed as follows: 

• Total number of reports received for AMBEX bulletin during the monitoring period, include 

reports in the retard bulletins. 

• Weed out correction and amendment bulletins, as these are re-transmitted messages, can be 

disregarded. 

(ii) Availability Index 

The availability index measures the current coverage of the OPMET distribution against the AMBEX 

exchange requirements. The determination of the availability index is performed on a daily basis from the 

data captured during the monitoring period. If at least one non-NIL report is received from the aerodrome 

during the 24-hour period, that aerodrome is considered to have been available. The daily availability 

index of a particular bulletin can be calculated as: 

Vbul availability = 

(iii) Regularity Index 

No of reports received for a bulletin 

No of reports required for the bulletin 

The regularity index measures the consistency in the number of reports provided by an aerodrome. The 

computation of Regularity Index assumes that the number of report follows a normal distribution and 

attempts to ascertain the distribution characteristics (mean and standard deviation) from a set of data. 

These 

characteristics are used to determine if subsequent number of reports from an aerodrome is “regular”. 

Denoting mean and standard deviation by μ and σ , a threshold report numbers (τ ) can be established as: 

τ = μ – σ 

The threshold is a reporting characteristic of an aerodrome. If the subsequent daily number of reports 

meets or exceeds the threshold, it is considered “regular”. The daily regularity index for a bulletin can be 

expressed as: 

Vbul regularity = 

No of aerodromes for which one or more non-NIL data type are received 

No of aerodromes required in the bulletins 

No of aerodromes for which the number of reports equals or exceeds the threshold 

No of aerodromes required in the bulletin 

2.2 Monitoring of non-scheduled OPMET data


2.2.1 Monitoring of non-scheduled OPMET data should be executed for FK, FV, WC, WS, and 

WV types of bulletins. 

2.2.2 The monitoring results should be presented in bulletin-oriented format, one line per 

bulletin indicating the abbreviated header (TTAAii CCCC YGGgg), the FIR/UIR where applicable, 

receipt time and originator. 

2.2.3 Example non-routine OPMET monitoring result file formats:

2.2.4 Analysis of Monitoring Results: 

2.2.4.1 Each RODB collects and analyses the relevant result in order to determine the 

effectiveness and suitability of the quality management system and to highlight any possible improvement 

to ICAO Regional Offices, Dakar and Pretoria.

1. INTRODUCTION 

1.1 The main purpose of this document is to provide guidance for standardization and 

harmonization of the procedures and formats related to the aeronautical meteorological warnings for 

hazardous en-route meteorological phenomena, known as SIGMET information. The guidance is 

complementary to the Annex 3 standards and recommended practices regarding SIGMET and to the 

SIGMET related provisions of the AFI Basic ANP and FASID, ICAO Doc 7474. 

1.2 ICAO provisions concerning the issuance and dissemination of SIGMET information are 

contained in: 

- Annex 3 - Meteorological Service for International Air Navigation, Part I, Chapter 3, 3.4 – 3.7, 

Chapter 7, 7.1, and Part II, Appendix 6; 

- AFI Basic ANP, Part I and VI, and AFIFASID Table MET 1B, MET 3A and MET 3B; 

- Annex 11 - Air Traffic Services, Chapter 4, 4.2.1 and Chapter 7, 7.1; 

- PANS – Air Traffic Management, Doc 4444, Chapter 9, 9.1.3.2; 

- Regional Supplementary Procedures, Doc 7030, Part 1, 8.2. 

Additional guidance on the SIGMET procedures is contained in the Manual of Aeronautical 

Meteorological Practice (Doc 8896), and the Manual on Coordination between Air Traffic Services, 

Aeronautical Information Services and Aeronautical Meteorological Services (Doc 9377). 

1.3 The SIGMET Guide is intended mainly to assist the MWOs in the ICAO African and 

Indian Ocean (AFIAFI) Region in preparing and disseminating SIGMET information. It provides detailed 

information on the format of SIGMET messages as specified by Annex 3. The explanations of the format 

are accompanied by examples based on region-specific meteorological phenomena. The guide also 

provides information regarding the necessary coordination between the MWOs, the ATS units and the 

pilots, and their respective responsibilities. 

1.4 This document was prepared by the ICAO AFI and ESAF Regional Offices. It is 

reviewed and updated regularly in order to be kept in line with the relevant ICAO SARPs and regional 

procedures. This current version incorporates the changes to SIGMET-related provisions included in 

Amendment 74 to Annex 3 which was approved by ICAO Council on 21 February 2007.

September 2007 Amend1/2010 Ninth Edition


2. RESPONSIBILITIES AND COORDINATION 

2.1 General 

2.1.1 SIGMET is warning information, hence it is of highest priority among other types of 

meteorological information provided to the aviation users. The primary purpose of SIGMET is for inflight 

service, which requires timely transmission of the SIGMET messages to pilots by the ATS units 

and/or through VOLMET and D-VOLMET. 

2.1.2 Airlines are the main users of the SIGMET information. They contribute to the 

effectiveness of the SIGMET service through issuance of special air-reports reported by pilots to the ATS 

units. Special air-reports are among the most valuable sources of information for the Meteorological 

Watch Offices (MWO) in the preparation of SIGMET. The ATS units receiving special air-reports should 

forward them to the associated MWOs without delay. 

2.1.3 In view of the foregoing, it should be well understood that the effectiveness of the 

SIGMET service depends strongly on the level of collaboration between the MWOs, ATS units and 

pilots. That is why, close coordination between these parties, as well as mutual understanding of their 

needs and responsibilities, are essential for the successful implementation of the SIGMET service. 

2.1.4 For the special cases of SIGMET for volcanic ash and tropical cyclones, the MWOs are 

provided with advisories from the volcanic ash advisory centres (VAAC), and tropical cyclone advisory 

centres (TCAC) designated in the Regional ANP. 

2.1.5 Another use of SIGMET is for the flight planning. This requires global dissemination of 

SIGMET through the international OPMET data banks and the satellite broadcasts: ISCS and SADIS. 

SIGMET should also be distributed to the World Area Forecast Centres (WAFC) London and 

Washington for use in the preparation of the significant weather (SIGWX) forecasts. 

2.1.6 In the next paragraphs, the main responsibilities and coordination links,related to the 

provision of SIGMET information, are described. 

2.2 Meteorological Watch Office - responsibilities and procedures related to SIGMET 

2.2.1 SIGMET information should be issued by the meteorological watch offices (MWO) in 

order to provide timely warning for occurrence or expected occurrence of specified en-route weather 

phenomena, affecting the safety of the flight operations in the MWO’s area of responsibility (AOR). 

SIGMET provides information concerning the location, extent, intensity and expected evolution of the 

specified phenomena. 

2.2.2 Information about the provision of SIGMET service, including details on the designated 

MWO(s), should be included in the State’s Aeronautical Information Publication (AIP) as specified in 

Annex 15, Aeronautical Information Service, Appendix 1, GEN 3.5.8. 

2.2.3 All designated MWOs in the AFI Region are listed in Appendix A to this Guide extracted 

from the FASID AFI Table MET 1B. The MWOs situated outside of the AFI Region are in italic. 

2.2.4 If, for some reason, a State is not able to meet its obligations for establishing MWO(s) 

and for provision of SIGMET for the FIR(s) or control area(s) the State is providing air traffic services, 

arrangements should be made between the meteorological authorities of the States concerned, that another 


AFI Regional SIGMET Guide Page 7/60 

MWOtakes over these responsibilities for certain period of time. Such delegation of responsibilities 

should be notified by a NOTAM and a letter to the ICAO Regional Office. 

2.2.5 Since the MWO is normally not a separate administrative unit, but part of the functions of 

an aerodrome meteorological office or other meteorological office, the meteorological authority 

concerned should ensure that the MWO obligations and responsibilities are clearly defined and assigned 

to the unit designated to serve as MWO. Corresponding operational procedures should be established and 

the meteorological staff should be trained accordingly. 

2.2.6 In preparing SIGMET information MWOs should follow strictly the format determined 

in Annex 3 (detailed format description is provided in Appendix 6, Table A6-1 of Annex 3). SIGMET 

should be issued only for those weather phenomena listed in Annex 3 and only when specified criteria for 

their intensity and spatial extent are met. 

Note: MWOs should not issue SIGMET for weather phenomena of lower intensity or such 

of transient nature or smaller scale, which do not affect significantly the flight safety and 

their transmission to users may lead to unnecessary precautionary measures. 

2.2.7 The MWOs should be adequately equipped in order to be able to identify, analyze and 

forecast (to the extent required) those phenomena for which SIGMET is required. The MWO should 

make use of all available sources of information, such as special air-reports, information from 

meteorological satellites and weather radars. 

2.2.8 On receipt of a special air-report from the associated ACC or FIC, the MWO should: 

a) issue SIGMET information based on the special-air report; or 

b) send the special air-report for on-ward transmission in case that the issuance of 

SIGMET information is not warranted (e.g., the phenomenon concerned is of 

transient nature). 

2.2.9 Appropriate telecommunication means should be available at the MWO in order to 

ensure timely dissemination of SIGMET according to a dissemination scheme, which should include 

transmission to: 

- Local ATS users; 

- Aeronautical MET offices within its AOR, where SIGMET is required for 

briefing and/or flight documentation; 

- Other MWOs concerned (it should be ensured that SIGMET is sent to all MWOs 

whose AORs are, at least partly, within the 1800 km (1000 NM) range from the 

observed phenomenon); 

- Centres designated for transmission of VOLMET or D-VOLMET where 

SIGMET is required for those transmissions; 

- Responsible AMBEX centre and Regional OPMET Data Bank (it should be 

arranged that through the AMBEX scheme SIGMETs are sent to the designated 

OPMET data banks in the other ICAO regions, to the WAFCs and to the SADIS 

and ISCS providers); 



- Responsible TCAC or VAAC according to FASID Tables MET 3A and MET 

3B. 

2.2.10 In issuing SIGMET for tropical cyclones or volcanic ash, the MWOs should include as 

appropriate the advisory information received from the responsible TCAC or VAAC. In addition to the 

information received from the TCAC and VAAC the MWOs may use the available complementary 

information from other reliable sources. In such a case the responsibility for this additional information 

would lie completely on the MWO concerned. 

2.3 Responsibilities of ATS units 

2.3.1 Close coordination should be established between the MWO and the corresponding ATS 

unit (ACC or FIC) and arrangements should be in place to ensure: 

- receipt without delay and display at the relevant ATS units of SIGMET issued by 

the associated MWO; 

- receipt and display at the ATS unit of SIGMETs issued by MWOs responsible for 

the adjacent FIRs/ACCs if these SIGMETs are required according to para2.3.4 

below, (within 1800 km (1000 NM) range from the observed phenomenon); and 

- transmission without delay by the ATS unit of special air-reports received through 

voice communication to the associated MWO. 

2.3.2 SIGMET information should be transmitted to aircraft with the least possible delay on the 

initiative of the responsible ATS unit, by the preferred method of direct transmission followed by 

acknowledgement or by a general call when the number of aircraft would render the preferred method 

impracticable. 

2.3.3 SIGMET information transmitted to aircraft-in-flight should cover a portion of the route 

up to two hours flying time ahead of the aircraft. SIGMET should be transmitted only during the time 

corresponding to their period of validity (p. 3.4.2.3 refers). 

2.3.4 Air traffic controllers should ascertain whether any of the currently valid SIGMETs may 

affect any of the aircraft they are controlling, either within or outside the FIR/CTA boundary, up to a 

distance of 1000 NM (1800 KM), which corresponds to two hours flying time ahead of the current 

position of the aircraft. If this is the case, the controllers should at their own initiative transmit the 

SIGMET promptly to the aircraft-in-flight likely to be affected. If necessary, the controller should pass to 

the aircraft available SIGMETs issued for the adjacent FIR/CTA, which the aircraft will be entering, if 

relevant to the expected flight route. 

2.3.5 The ATS units concerned should also transmit to aircraft-in-flight the special air reports 

received, for which SIGMET has not been issued. Once a SIGMET for the weather phenomenon reported 

in the special air report is made available this obligation of the ATS unit expires. 



2.4 Responsibilities of pilots 

2.4.1 Timely issuance of SIGMET information is largely dependant on the prompt receipt by 

MWOs of special air-reports. That is why, it is essential that pilots prepare and transmit such reports to 

the ATS units whenever any of the specified en-route conditions are encountered or observed. 

2.4.2 It should be emphasized that, even when automatic dependent surveillance (ADS) is 

being used for routine air-reports, pilots should continue to make special air-reports. 

2.5 Coordination between MWOs and the TCACs and VAACs 

2.5.1 Amongst the phenomena for which SIGMET information is required, the volcanic ash 

clouds and tropical cyclones are of particular importance for the planning of long-haul flights. 

2.5.2 Since the identification, analysis and forecasting of volcanic ash and tropical cyclones 

requires considerable technical and human resource, normally not available at each MWO, the Volcanic 

Ash Advisory Centres (VAAC) and Tropical Cyclone Advisory Centres (TCAC) have been designated to 

provided VA and TC advisories to the users and assist the MWOs in the preparation of the forecast part of 

the SIGMETs for those phenomena. Close coordination should be established between the MWO and its 

responsible TCAC and/or VAAC. 

2.5.3 Information regarding the VAACs and TCACs serving the AFIRegionwith their 

corresponding areas of responsibility and lists of MWOs and ACCs to which advisories are to be sent is 

provided in FASID Tables MET 3A and MET 3B of the AFIFASID. These tables are reproduced in 

Appendix B and Appendix C to this Guide. 

2.5.4 TC and VA advisories are required for global exchange through the satellite distribution 

systems, SADIS and ISCS. They are used by the operators during the preflight planning. Nevertheless, it 

should be emphasized that SIGMET information is still of higher operational status and is required 

especially for in-flight re-planning. SIGMETs should be transmitted to aircraft-in-flight through voice 

communication or VOLMET or D-VOLMET thus providing vital information for making in-flight 

decisions regarding large-scale route deviations due to volcanic ash clouds or tropical cyclones.

3. PROCEDURES FOR PREPARATION OF SIGMET INFORMATION 

3.1 General 

3.1.1 SIGMET information is prepared in abbreviated plain language using approved ICAO 

abbreviations, a limited number of non-abbreviated words, geographical names and numerical values of 

self-explanatory nature. All abbreviations and words to be used in SIGMET are given in Appendix D. 

3.1.2 The increasing use of automated systems for handling the MET information by the 

aviation users makes it essential that all types of OPMET information, including SIGMET, are prepared 

and transmitted in the prescribed standardized formats. Therefore, the structure and format of the 

SIGMET message, as specified in Annex 3, Part II, Appendix 6, which provides detailed information 

regarding the content and order of elements in the SIGMET message, should be followed strictly by the 

MWOs. 

3.1.3 SIGMET is intended for transmission to aircraft in flight either by ATC or by VOLMET 

or D-VOLMET. Therefore, SIGMET messages should be kept conciseand clear without additional 

descriptive text other than the prescribed in Annex 3. 

3.1.4 After the issuance of a SIGMET the MWO should maintain watch over the evolution of 

the phenomenon for which the SIGMET has been issued and issue updated SIGMET when necessary. 

The TC and VA SIGMET should be updated at least every 6 hours. 

3.1.5 SIGMET should be promptly cancelled when the phenomenon is no longer occurring or 

no longer expected to occur in the MWO’s area of responsibility. The SIGMET is understood to cancel 

itself automatically at the end of its validity period. If the phenomenon persists a new SIGMET message 

for a further period of validity should be issued. 

3.2 Types of SIGMET 

3.2.1 Although Annex 3 provides one general SIGMET format, which encompasses all weather 

phenomena, it is convenient when describing the structure and format of the messages to distinguish 

between three types of SIGMET, as follows: 

- SIGMET for en-route weather phenomena other than VA and TC (this includes: 

TS, CB, TURB, ICE, MTW, DS and SS); this SIGMET will be referred as WS 

SIGMET; 

- SIGMET for volcanic ash, which will hereafter be denoted as VA SIGMET or WV 

SIGMET; and 

- SIGMET for tropical cyclones, which will hereafter be denoted as TC SIGMET or 

WC SIGMET. 

3.2.2 The three types of SIGMET can be identified by the data type designator included in the 

WMO abbreviated heading of the SIGMET message, as explained below. 

3.3 Structure of the SIGMET message 

3.3.1 A SIGMET message consists of: 

- WMO heading – all SIGMETs are preceded by an appropriate WMO heading; 



- First line, containing location indicators of the respective ATS unit and MWO, 

sequential number and period of validity; 

- SIGMET main body, containing information concerning the observed or forecast 

weather phenomenon for which the SIGMET is issued together with its expected 

evolution within the period of validity; 

3.3.2 The first two parts of the SIGMET message are common for all types of SIGMET. The 

format and content of the third part is different; that is why, in the following paragraphs the 

meteorological part of the SIGMET message is described separately for the three types of SIGMET. 

3.4 Format of SIGMET 

Note: In the following text, square brackets - [ ] - are used to indicate an optional or conditional 

element, and angled brackets - - for symbolic representation of a variable element, which in a real 

SIGMET accepts concrete numerical value. 

3.4.1 WMO Header 

T1T2A1A2ii CCCC YYGGgg [CCx] 

3.4.1.1 The group T1T2A1A2ii is the bulletin identification for the SIGMET message. It is 

constructed in the following way: 

T1T2 Data type designator WS – for SIGMET for meteorological phenomena other than 

volcanic ash cloud or tropical cyclone 

WC – for SIGMET for tropical cyclone 

A1A2 Country or territory 

designators 

WV – for SIGMET for volcanic ash 

Assigned according to Table C1, Part II of Manual on the Global 

Telecommunication System, Vol I – Global Aspects (WMO - No. 

386) 

ii Bulletin number Assigned on national level according to p 2.3.2.2, Part II of 

Manual on the Global Telecommunication System, Vol I – Global 

Aspects (WMO - No. 386) 

3.4.1.2 CCCC is the ICAO location indicator of the communication centre disseminating the 

message (could be the same as the MWO location indicator). 

3.4.1.3 YYGGgg is the date/time group, where YY is the date and GGgg is the time of 

transmission of the SIGMET in hours and minutes UTC (normally this time is assigned by the 

disseminating (AFTN) centre). 

3.4.1.4 The group CCx should be used only when issuing a correction to a SIGMET which had 

already been transmitted.The third letter “x” takes the value A for the first correction, B for the second 

correction, etc. 

Examples: 

WSSG31 GOOY121200 

WVCV31 GVAC 010230 

WCGG31FCBB 100600 CCA 



3.4.2 First line of SIGMET

date/time group of the end of the period (see p.3.4.2.3) 

CCCC ICAO location indicator of the issuing MWO 

- hyphen to separate the preamble from the text 

3.4.2.2 The numbering of SIGMETs starts every day at 0001 UTC. The sequence number should 

consist of up to three symbols and may be a combination of letters and numbers, such as: 

- 1, 2, … 

- 01, 02, … 

- A01, A02, … 

Examples: 

GOOO SIGMET 2 VALID 121100/121700 GOOY- 

DGACSIGMET A04 VALID 202230/210430 DGAA- 

Note 1: No other combinations should be used, like “CHARLIE 05” or “NR7”. 

Note 2: Correct numbering of SIGMET is very important since the number is used for reference in 

communication between ATC and pilots and in VOLMET and D-VOLMET. 

3.4.2.3 The following considerations should be taken into account when determining the validity 

period: 

- The period of validity of a WS SIGMET should not be more than 4 hours; 

- The period of validity of a WC or WV SIGMET should not be more than 6 hours; 

- In case of a SIGMET for an observed phenomenon, the filing time (date/time group 

in the WMO header) should be the same or very close to the time in the date/time 

group indicating the start of the SIGMET validity period; 

- When the SIGMET is issued for a forecast phenomenon: 

o the beginning of validity period should be the time of the expected 

commencement (occurrence) of the phenomenon in the MWO area of 

responsibility; 

o the time of issuance of the SIGMET should not be more than 4 hours before 

the start of validity period (i.e., expected time of occurrence of the 

phenomenon); for TC and VA SIGMET the lead time should be up to 12 

hours. 

3.4.2.4 The period of validity is that period during which the SIGMET information is valid for 

transmission to aircraft in flight.

3.4.3.1.2 Phenomenon(Column 2) 

The phenomenon description consists of a qualifier and a phenomenon abbreviation. 

SIGMET should be issued only for the following phenomena: 

at cruising levels (irrespective of altitude): 

- thunderstorms (TS) – if they are OBSC, EMBD, FRQ or SQL with or 

without hail; 

- turbulence (TURB) – only SEV 

- icing (ICE) – only SEV with or without FZRA 

- mountain waves (MTW) – only SEV 

- dust storm (DS) – only HVY 

- sand storm (SS) – only HVY 

- radioactive cloud – RDOACT CLD 

The appropriate abbreviations and combinations, and their meaning are given in Appendix E. 

3.4.3.1.3 Indication whether the phenomenon is observed or forecast(Column 3) 

OBS [AT Z] 

or FCST 

The indication whether the phenomenon is observed or forecast is given by using the 

abbreviations OBS or FCST. OBS is followed by anoptionaltime group in the form AT GGggZ, where 

GGgg is the time of the observation in hours and minutes UTC. If the exact time of the observation is not 

known the time is not included. When FCST is used, it is assumed that the time of occurrence or 

commencement of the phenomenon coincides with the beginning of the period of validity included in the 

first line of the SIGMET. 

Examples: 

OBS AT 0140Z 

FCST 

3.4.3.1.4 Location of the phenomenon(Column 4) 

The location of the phenomenon is given with reference to geographical coordinates 

(latitude and longitude) or with reference to geographical features well known internationally. The 

MWOs should try to be as specific as possible in reporting the location of the phenomenon and, at the 

same time, to avoid overwhelming geographical information, which may be difficult to process or 

perceive. 

The following are the most common ways to describe the location of the phenomenon: 

- Indication of a part of the FIR with reference to latitude: 

N OF or S OF or 

- Indication of a part of the FIR with reference to longitude: 



E OF or W OF or 

- Indication of a part of the FIR with reference to latitude and longitude: 

any combination of the above two cases; 

- with reference to a location with ICAO location abbreviation CCCC (normally, this 

should be the case of SIGMET based on special air-report in which the reported 

phenomenon is given with reference to an airport or another object with ICAO 

location indicator CCCC); 

- with reference to geographical features well known internationally. 

More details on reporting the location of the phenomenon are given in Appendix 6 to

VA [ERUPTION] [MT ] [LOC ] VA CLD 

or 

VA CLD 

3.4.4.2.1 The description of the volcano injecting volcanic ash consists of the following elements: 

- starts with the abbreviation VA – volcanic ash; 

- the word ERUPTION is used when the SIGMET is issued for a known volcanic 

eruption; 

- geographical/location information: 



i. if the name of the volcano is known, it is given by the abbreviation MT – 

mountain, followed by the name; 

e.g., MT RABAUL 

ii. location of the volcano is given by the abbreviation LOC – location, 

followed by the latitude and longitude in degrees and minutes; 

e.g., LOC N3520 E09040 

- this section of the message ends with the abbreviation VA CLD – volcanic ash 

cloud. 

3.4.4.2.2 If the FIR is affected by a VA cloud with no information about the volcanic eruption 

which generated the cloud, only the abbreviation VA CLD should be included in the SIGMET. 

3.4.4.3 Time of observation or indication of forecast(Column 3) 

VA CLD OBS AT Z 

or 

VA CLD FCST 

The time of observation is taken from the source of the observation – satellite image, 

special air- report, report from a ground volcano logical station, etc. If the VA cloud is not yet observed 

over the FIR but the volcanic ash advisory received from the responsible VAAC indicates that the cloud 

is going to affect the FIR within the next 12 hrs, SIGMET should be issued, according to paragraph 2.4 

above, and the abbreviation VA CLD FCST should be used. 

Examples: 

VA CLD OBS AT 0100Z 

VA CLD FCST 

3.4.4.4 Level and extent of the volcanic ash cloud(Column 4) 

FL [APRX KM BY KM] [] 

or 

FL [APRX NM BY NM] [] 

FL The layer of the atmosphere where the VA cloud is situated, 

given by two flight levels from the lower to the upper 

boundary of the cloud

[APRX NM BY NM] NM 

[] Approximate description of the VA cloud by a number of 

points given with their geographical coordinates 1 ; the points 

should be separated by hyphen 

If the VA cloud spreads over more than one FIR, separate SIGMETs should be issued by 

all MWOs whose FIRs are affected. In such a case, the description of the volcanic ash cloud by each 

MWO should encompass the part of the cloud, which lies over the MWO’s area of responsibility. The 

MWOs should try and keep the description of the volcanic ash clouds consistent by checking the 

SIGMET messages received from the neighbouring MWOs. 

1 The format of geographical coordinates reporting in SIGMET is given in Appendix E. 



Examples: 

FL100/180 APRX 10KM BY 50KM N0100 E09530 – N1215 E11045

3.4.4.6 Forecast position of the VA cloud at the end of the validity period of the SIGMET 

message(Column 6) 

FCST Z VA CLD APRX 

3.4.4.6.1 The GGggZ group should indicate the end of validity period given in the first line of the 

SIGMET message. The description of the expected position of the volcanic ash cloud is given by a 

number of points forming a simplified geometrical approximation of the cloud. 

3.4.4.6.2 In describing the VA cloud up to four different layers can be used, indicated by flight 

levels in the form FL. The use of more than one level is necessary when the wind direction 

distribution with height determines that the cloud is spread horizontally into different directions at 

different height layers. 

3.4.5 Structure of the meteorological part of TC SIGMET

3.4.5.2 Name of the tropical cyclone(Column 2) 

TC 

The description of the tropical cyclone consists of the abbreviation TC followed by the 

international name of the tropical cyclone given by the corresponding WMO RSMC. 

Examples: 

TC GLORIA 

TC 04B 

3.4.5.3 Time of observation or indication of forecast(Column 3.1) 

OBS AT Z 

or 

FCST 

The time in UTC is given in hours and minutes, followed by the indicator Z. Normally, 

time is taken from own observations or from a TC advisory received from the responsible TCAC. If the 

TC is not yet observed in the FIR but the tropical cyclone advisory received from the responsible TCAC, 

or any other TC forecast used by the MWO, indicates that the TC is going to affect the FIR within the 

next 12 hrs, SIGMET should be issued, according to paragraph 2.4 above, and the abbreviation FCST 

should be used. 

Examples: 

OBS AT 2330 



3.4.5.4 Location of the TC centre(Column 3.2) 

 

The location of the TC centre is given by its lat,lon coordinates in degrees and minutes.

Examples: 

MOV NW 30KMH 

MOV E 25KT 

3.4.5.7 Intensity change(Column 6) 

The expected change of the intensity of the tropical cyclone is indicated by one of the 

following abbreviations: 

INTSF – intensifying 

WKN – weakening 

NC – no change 

3.4.5.8 Forecast location of the TC centre at the end of the validity period of the SIGMET 

message(Column 7) 

FCST Z TC CENTRE 

Normally, the time given by GGggZ should be the same as the end of validity period 

indicated in the first line of the SIGMET message. Since the period of validity is up to 6 hours (normally, 

6 hours), this is a 6-hour forecast of the position of the TC centre. 



The location of the TC centre is given by its lat, lon coordinates following the general 

rules of reporting lat, lon information provided in Appendix F to this Guide. 

Examples: 

FCST 1200Z TC CENTRE N1430 E12800 

3.4.6 Cancellation of SIGMET 

3.4.6.1 If during the validity period of a SIGMET the phenomenon for which the SIGMET had 

been issued is no longer occurring or no longer expected, the SIGMET should be cancelled by the issuing 

MWO. The cancellation is done by issuing same type of SIGMET with the following structure: 

- WMO heading with the same data type designator; 

- First line that contains as period of validity the remaining time of the original period 

of validity; 

- Second line, which contains the name of the FIR or CTA, the combination CNL 

SIGMET, followed by the sequential number of the original SIGMET and its validity 

period.

3.5.1 SIGMET information is part of the operational meteorological (OPMET) information. 

According to Annex 3 the telecommunication facilities used for the exchange of the operational 

meteorological information should be the aeronautical fixed service (AFS). 

3.5.2 The AFS consists of a terrestrial segment, AFTN or ATN (AMHS), and a satellite 

segment which comprises the SADIS and ISCS satellite broadcasts provided by the UK and the USA 

respectively. 

3.5.3 Currently, AFTN links should be used by the MWOs to send the SIGMET, as follows: 

− to the adjacent MWOs and ACCs * using direct AFTN addressing; 

− When required for VOLMET or D-VOLMET, SIGMET should be sent to the 

relevant centre providing the VOLMET service; 

− SIGMET should be sent to all regional OPMET Data Banks (RODB); 

− It should be arranged that SIGMET is relayed to the SADIS and ISCS providers for 

satellite dissemination, as well as to the WAFCs London and Washington, either 

through the AMBEX scheme, or directly by the issuing MWO; 

− SIGMET for volcanic ash should be disseminated to the responsible VAAC. 

3.5.4 Through SADIS and ISCS, SIGMET is disseminated to all authorised users . In this way, 

SIGMET is available on a global basis, meeting the aeronautical requirements. 

* Note: For this dissemination it is required that SIGMET is available at the ACCs 

for transmission to aircraft in flight for the route ahead up to a distance corresponding to 

two hours flying time.

2. Obscured (OBSC) indicates that the thunderstorm (including, if necessary, CB-cloud which is not 

accompanied by a thunderstorm) is obscured by haze or smoke or cannot be readily seen due to 

darkness 

3. Embedded (EMBD) – indicates that the thunderstorm (including, if necessary, CB-cloud which is 

not accompanied by a thunderstorm) is embedded within cloud layers and cannot be readily 

recognized 

4. Frequent (FRQ) indicates an area of thunderstorms within which there is little or no separation 

between adjacent thunderstorms with a maximum spatial coverage greater than 75% of the area 

affected, or forecasts to be affected, by the phenomenon (at a fixed time or during the period of 

validity) 

5. Squall line (SQL) indicates thunderstorms along a line with little or no space between individual 

clouds 

6. Severe (SEV) turbulence (TURB) refers only to: 

- low-level turbulence associated with strong surface winds; 

- rotor streaming; 

- turbulence whether in cloud or not in cloud (CAT) near to jet streams. 

Turbulence is consideredsevere whenever the peak value of the cube root of EDR exceeds 0.7. 

7. A mountain wave (MTW) is considered severe – whenever an accompanying downdraft of 3.0 m/s 

(600 ft/min) or more and/or severe turbulence is observed or forecast. 

—————————— 



APPENDIX F: Standard for Reporting Geographical Coordinates in SIGMET 

When reporting geographical coordinates of points in SIGMET the following should apply: 

1. Each point is represented by a latitude/longitude coordinates in whole degrees or degrees and 

minutes in the form: 

N(S)nn[nn] W(E)nnn[nn] 

Note: There is a space between the latitude and longitude value. 

Examples: N0518 W00401 Abidjan 

S0419 E01519 Kinshasa 

N1443 W01728 Dakar 

2. In describing lines or polygons, the lat,lon values of the respective points are separated by the 

combination space-hyphen-space, as in the following examples: 

N1334 W00739 – N1327 W01635 – N0932 W1340– N0518 W00401 (Bamako, Banjul, Conakry, 

Abidjan) 

S05 E093 – N01 E095 – N12 E110 – S08 E103 

Note: It is not necessary to repeat the first point when describing a polygon. 

3. When describing a volcanic ash cloud approximate form and position, a limited number of points, 

which form a simplified geometric figure (a line, or a triangle, or quadrangle, etc.) should be used in order 

to allow for a straightforward interpretation by the user. 

4. Reporting a phenomenon occupying two different geographical areas within the FIR. This is 

frequently the case with two (or more) separate TS formations occurring in different parts of the FIR at 

the same time. The question is whether a separate SIGMET should be issued for each formation, or, one 

SIGMET could include location description for two (or more) geographical areas. The current SIGMET 

format does not allow for reporting of more than one phenomenon or two different TS areas. Therefore, in 

cases like this, two separate SIGMETs should be issued. The main concern with issuing separate 

SIGMETs is that, in general, a new SIGMET for the same FIR would replace the previous one; this may 

lead to rejecting valid information in case as described above. It should be noted in this regard, that the 

current SIGMET format allows for using different sequence numbers and thus, for keeping more than one 

SIGMET at a time valid for the FIR concerned; for instance, a series A1, A2,… could be used for 

“phenomenon A” and B1, B2, … , for “phenomenon B”.

FIR around 0800Z. The responsible MWO, YUSO receiving this advisory prepares a SIGMET for the 

expected penetration of the VA cloud in its FIR and this SIGMET is send at 0230Z.

1. Introduction 

APPENDIX J - AFI SIGMET Test Procedures 

(Amendment 1 – May 2010) 

1.1 The MET Divisional Meeting (2002) formulated recommendation 1/12 b), 

Implementation of SIGMET requirements, which call, inter alia, for the relevant planning and 

implementation regional groups (PIRGs) to conduct periodic tests of the issuance and reception of 

SIGMET messages, especially those for volcanic ash. 

1.2 Concerns by the users for the timely reception of SIGMET information has prompted the 

need to improve awareness on the critical and important nature of SIGMETs. In order to maintain the 

International Airways Volcano Watch (IAVW) and TC watch systems ready-for-action, regular exercises 

involving the advisory centres and the MWOs under their areas of responsibility should be performed. 

1.3 The requirements for dissemination of SIGMET are specified in Annex 3, Appendix 6, 

1.2. Regional guidance on the preparation and dissemination of SIGMET is provided in this Regional 

SIGMET Guide. 

2. Purpose and Scope of SIGMET tests 

2.1 The purpose of the tests is to check the awareness of the participating MWOs of the 

ICAO requirements for the issuance of SIGMET, and the adequacy of the existing telecommunication 

procedures for dissemination of the advisories and SIGMETs. Based on the results of the tests, the States 

will be provided with advice aimed at improving their practices and procedures. 

2.2 In the case of SIGMET for tropical cyclones and volcanic ash clouds (referred hereafter 

as WC SIGMET and WV SIGMET respectively) the scope of the tests will involve issuance of test 

advisories by the VAACs and TCACs in the region, which will be disseminated to the corresponding 

MWOs and the Regional OPMET Data Banks (RODBs). The MWOs will have to issue a test SIGMET 

on receipt of a test advisory from the responsible VAAC or TCAC, and disseminate it according to the 

distribution list used for normal (non-test) SIGMETs. 

2.3 The RODBs will record the reception of the test SIGMETs and the corresponding time 

and will provide a summary table to the VAAC or TCAC with a copy to the Regional Office. 

2.4 A consolidated summary report will be prepared by the ICAO Secretariat and reported to 

the MET/SG and APIRG. The report will include recommendations for improvement of the SIGMET 

exchange and availability.

3.1.3.1 Each VAAC or TCAC prepares a simple TEST message in the form of VA or TC 

advisory. The formats of the said TESTsare given in Attachment 1 to this Appendix. 

3.1.3.2 The MWOs, upon receipt of the TEST VA/TC advisory, should prepare a TEST 

SIGMET for volcanic ash or tropical cyclone, respectively, and send it to the RODBs. The WMO heading 

and the first line of the SIGMET should be valid ones, while the body of the message should contain an 

explanatory text on the testsas show in Attachment 1 to this Appendix. 

3.1.3.3 The MWOs should issue a WV or WC TEST SIGMET within the 10-minute period 

following the issuance of VA or TC test message by the corresponding VAAC or TCAC. 

3.2 Procedures for WS SIGMET Tests 

3.2.1 WS SIGMET advisory Test should be initiated by Pretoria RODB in coordination with 

ICAO Regional Offices in Dakar and Nairobi. The information about the date and time will be sent to all 

States concerned and copied to the State’s SIGMET Tests Focal Points. 


J-2


3.2.2 Operational Units: 

-AFI Regional OPMET data Banks: Dakar and Pretoria. 

-Meteorological Watch Offices ( MWO): All MWOs listed in FASID Table MET 3A and 

MET 3B of the AFI FASID. 

3.3 Common Procedures Applicable to All Types of SIGMET 

3.3.1 The AFTN addresses of the RODBs to which the test SIGMETs should be sent are as 

follows: 

Dakar : GOOYYZYZ 

Pretoria : FAPRYMYX 

3.3.2 To avoid over-writing of a valid SIGMET, the test SIGMET may not be sent if there is a 

valid SIGMET for responsible area of the MWO. Such MWOs are strongly encouraged to notify the 

Regional Office via e-mail of their non-participation in the test due to the said reasons. 

3.3.3 Test for different types of SIGMET should preferably be conducted on separate dates. 

3.3.4 At least two SIGMET tests per year should be conducted. 

3.4 Special procedure to avoid overwriting of a valid SIGMET 

3.4.1 It is vital to ensure that TEST SIGMET is not confused with operational SIGMET and 

avoid overwriting a valid operational SIGMET in an automated system. In order to prevent this it is 

suggested that: 

a) If at the time of the SIGMET test NO SIGMET is current for the FIR, the number of the Test 

SIGMET should follow the normal numbering sequence; e.g. if the last “normal” SIGMET before 

the test was number “03”, 

b) the TEST SIGMET should be number “04”, and the first “normal” SIGMET after the test should 

be number “05”.If a SIGMET is VALID at the time of the test then the TEST SIGMET should be 

issued and the valid SIGMET should be repeated immediately after the TEST SIGMET. E.g., if 

the following SIGMET is issued at 0100 on the date of the test: 


J-3




FCCC BRAZZAVILLE FIR SEV TURB FCST WI ….= 

A SIGMET test is scheduled for 0200 UTC on the 25 th . The TEST SIGMET is 

issued with the next consecutive sequence number as follows: 



FCCC THIS IS A TEST SIGMET PLEASE DISREGARD= 

The original SIGMET is then retransmitted immediately after this with the next 

consecutive sequence number and the validity period is amended accordingly: 



FCCC BRAZZAVILLE FIR SEV TURB FCST WI … = 

4. Dissemination of test SIGMETs and Advisories 

4.1 All TEST SIGMETs and TC/VA advisories should be sent to the two AFI RODBs. The 

AFTN addresses to be used by the MWOs, TCACs and VAACs are as follows: 

Dakar – GOOYYZ YZ 

Pretoria – FAPRYMYX 

4.2 SIGMET tests should be terminated within 2 hours of the test start time. 

4.3 Coordination with the ATS units 

4.3.1 MWOs should inform the associated ATS units of the forthcoming SIGMET tests by a 

suitable advanced notice. 

4.4 Processing of the test messages and results 

4.4.1 The RODBs will be requested to file all incoming TEST advisories and SIGMETs and 

perform an analysis of the availability, timeliness of arrival for WV and WC SIGMETs and the 

correctness of the headers and meteorological content of WS SIGMET. A SIGMET TEST Summary 

Table as shown in Attachment 4 to this Appendix should be prepared by each RODB and sent to the 

Rapporteur of the AFI OPMET Management Task Force (AFI OPMET MTF), and the contact given 

below with a copy to the ICAO Dakar and Nairobi Regional Office. 

4.4.2 The Rapporteur and SIGMET test contact should prepare the final report of the test and 

present it to the AFI Regional Offices. A summary report should be submitted to the next AFI OPMET 

MTF meeting. 

4.4.3 The current contact information for sending summary tables is as follows :

Page 3 of 29 


1.1 Within and adjacent to the Africa and Indian Ocean (AFI) Region there are areas of volcanic activities 

which are likely to affect flight in the AFI Region. The major volcanoes in the region are located in the following States: 

Algeria, Cameroon, Cape Verde Islands, Chad, Comoros Island, Democratic Republic of Congo, Djibouti, Eritrea, 

Ethiopia, France (Reunion Island), Kenya, Madagascar, Mali, Niger, Nigeria, Rwanda, Sao Tome and Principe, Spain 

(Canary Islands, Madeira), Sudan, Tanzania and Uganda. The names of the concerned volcano are listed in Attachment 

L (source: Smithsonian Institution). 

1.2 The AFI Air Traffic Management (ATM) Volcanic Ash Contingency Plan sets out standardised guidelines 

for the alerting of aircraft when eruptions occur, and procedures to be followed. Volcanic contaminations, of which 

volcanic ash is the most serious, may be a hazard for flight operations; the issue cannot be resolved in isolation but 

through collaborative decision-making (CDM) involving all entities concerned. During an eruption volcanic 

contamination can reach and exceed the cruising altitudes of turbine-powered aeroplanes within minutes and spread 

over vast geographical areas within a few days. Encounters with volcanic ash may result in one or more of the following 

and other problems: 

• the malfunction, or failure, of one or more engines leading not only to reduction, or complete loss, of 

thrust but also to failures of electrical, pneumatic and hydraulic systems; 

• blockage of pitot and static sensors resulting in unreliable airspeed indications and erroneous warnings; 

• windscreens to be rendered partially or completely opaque; 

• smoke, dust and/or toxic chemical contamination of cabin air requiring crew use of oxygen masks, thus 

impacting communications; electronic systems may also be affected; 

• erosion of external and internal aircraft components; 

• reduced electronic cooling efficiency leading to a wide range of aircraft system  failures; 

• aircraft to be manoeuvred in a manner that conflicts with other aircraft; 

• deposits of volcanic ash on a runway degrading braking performance, most significantly if the ash is 

wet; in extreme cases, this can lead to runway closure. 

1.3 Operators are required by ICAO Annex 6 – Operation of Aircraft to assess the risk of operation in volcanic 

ash and to implement appropriate mitigation measures in accordance with their safety management system (SMS) as 

approved by the State of the Operator/Registry, as appropriate. The suggested actions outlined in this document are 

based on the assumption that the ICAO requirements regarding safety management systems have been implemented by 

the operators. Detailed guidance on Safety Risk Assessments for flight operations with regard to volcanic contamination 

is available at .... (ICAO Doc####) 

1.4 It should be noted that this document is an ATM contingency plan including its interfaces with supporting 

services such as Aeronautical Information Service (AIS) and Meteorological (MET) services and that the plan therefore 

primarily addresses the provider States. Where distinct actions by the Meteorological Watch Offices (MWOs) are 

described, these are additional procedures to be considered by MWOs. Where actions by Volcanic Ash Advisory 

Centres (VAACs) and operators are described, these are for clarification only. As volcanic events also affect people and 

industries that are not related to aviation, it is highly likely that contingency plans of a more generic ―disaster response‖ 

nature exist in many States. Since they too rely on information sources, such as Volcanological Observatories, it is 

advisable to make arrangements to share information with institutions. 

1.5 Volcanic Ash can also affect the operation of aircraft on aerodromes. In extreme cases, aerodromes might 

no longer be available for operation at all, resulting in repercussions on the ATM system; e.g. diversions, revised traffic 

flow, etc. 

1.6 These suggested procedures are not intended to establish or confirm a safe level of volcanic contamination. 

Operation through any area where volcanic ash is present or forecast is at the discretion of the operator. In this context it 

should be noted that some aircraft types or engine technologies are more vulnerable to volcanic contaminants; any 

specific measures to be applied would therefore have to take into account these variances. Considering that a 

commercial aircraft will travel about 150 km (80 NM) in 10 minutes and that volcanic ash can rise to flight levels

Page 4 of 29 


commonly used by turbine-engine aeroplanes in half that time, a timely response to reports of volcanic ash is essential. 

1.7 It is imperative that information on the volcanic activity is disseminated as soon as possible. In order to 

assist staff in expediting the process of originating and issuing relevant messages (VA SIGMET, NOTAM, and 

ASHTAM), a series of templates should be available for different stages of the volcanic activity. Examples of VA 

SIGMET, NOTAM and ASHTAM announcing operational measures and volcanic activities in the different stages and 

are contained in Attachment K. A list of ICAO registered volcanoes should be available at the international NOTAM 

office with volcano name, number and nominal position. In order to ensure the smooth implementation of the 

contingency plan in case of an actual volcanic eruption, annual AFI ATM/MET Task Force Volcanic Ash Exercises 

(VAEX/AFI) should be conducted. 

2. TERMINOLOGY 

2.1 Areas of Contamination 

2.1.1 Areas of volcanic ash contamination are provided by means of volcanic ash advisories (VAAs) in 

accordance with the Meteorological Service for International Air Navigation (Annex 3). In the AFI region, 

contamination levels are provided by the associated MWO of AFI Volcanic Ash Advisory Centre (VAAC) actually 

located in Toulouse, France, by means of ash concentration forecasts/charts in order to support operators in establishing 

their safety risk assessment (SRA) for flight operations in known or forecast volcanic ash contamination. Whenever ash 

products are mentioned in this document this means variously VAA or VAG and in volcanic ash concentration charts. 

2.2 Phases of an Event 

2.2.1 The response to a volcanic event that affects air traffic has been divided into four distinct phases (Pre- 

Eruption Phase, Start of Eruption Phase, Ongoing Eruption Phase, and Recovery Phase) as described briefly below. The 

four phases cover an actual event only and do not describe activities that need to be performed before or after a volcanic 

event. However, it would be prudent to train all ATS personnel and to have regular exercises in how to deal with 

volcanic contaminations. In addition, following a volcanic event it would be good practice to perform a review of the 

actions, to identify lessons learnt, which should be taken into account in an update of the contingency plan. Volcanic 

activity at many locations is continuously monitored by the scientific community. Furthermore, flight crews are required 

to report observations of significant volcanic activity by means of a Special Air Report (AIREP). Arrangements should 

be put in place to ensure that such information is transferred without delay to the appropriate aeronautical institutions 

responsible for subsequent action. Reports (text to be included referring to Attachment C) 

PRE-ERUPTION PHASE: The initial response, “raising the alert”, commences when a volcanic 

eruption is expected. Alerting information will be provided by VA SIGMET, NOTAM or ASHTAM 

as appropriate and disseminated to affected aircraft in flight by the most expeditious means. In 

addition to the normal distribution list, the NOTAM/ASHTAM will be addressed to 

meteorological/volcanological agencies. 

2.2.2 If it is considered that the event could pose a hazard to aviation, a danger area will be declared by NOTAM 

around the volcanic source. Normally, clearances will not be issued through the danger area unless explicitly requested 

by the flight crew. In this context it should be noted that the final responsibility for aircraft safety rests with the pilot, 

therefore the final decision regarding route, whether it will be to avoid or proceed through an area of volcanic activity, is 

the pilot’s responsibility. Wherever this document discusses the possible establishment of danger areas, States are not 

prevented from establishing restricted or prohibited areas over the sovereign territory of the State if considered 

necessary by the State concerned. 

START OF ERUPTION PHASE: The start of eruption phase commences at the outbreak of the volcanic 

eruption and entrance of volcanic ash into the atmosphere and mainly pertains to aircraft in flight. A “Start of 

Eruption VA SIGMET” will be issued and a danger area will be declared by NOTAM. Normally, clearances 

will not be issued through the danger area unless explicitly requested by the flight crew.

Page 5 of 29 


ONGOING ERUPTION PHASE: The ongoing eruption phase commences with the issuance of the first 

VAA after completion of reactive responses. The T+0 hours and T+6 hours forecasts of the contaminated area 

are to be issued as VA SIGMET. The T+12 hours and T+18 hours (and further into the future) forecasts of 

contaminated areas are to be issued as VAA forecasts. Significant changes may result in a reversion to a 

temporary start of eruption phase situation and unscheduled issuance of VAA, VA SIGMET and 

NOTAM/ASHTAM 

RECOVERY PHASE: The recovery phase commences with the issuance of the first “No Volcanic Ash 

Expected VAA” which normally occurs when it is determined that the volcanic activity has reverted to its preeruption 

state. 

3. PRE-ERUPTION PHASE 

3.1 General 

3.1.1 Where flight operations are planned in areas that are susceptible to volcanic eruptions, a system of monitoring 

volcanoes should be established. As the lack of resources results in a large number of volcanoes unmonitored locally, 

pilots flying in the vicinity of a VA activity are frequently the first source of information on an eruption. Therefore, 

pilots operating in areas with unmonitored volcanoes should always be vigilant for signs of an eruption and should fully 

understand their importance as information providers. Operators should provide them with the ICAO Volcanic Activity 

Report form published in the Procedures for Air Navigation Services – Air Traffic Management (PANS-ATM, Doc 

4444) Attachment 1, preferably in an easily useable electronic format, as part of the pre-flight briefing. 

3.1.2 The focus of this phase is to gain early recognition of volcanic events. This phase is frequently characterised by 

a limited availability of information on the potential extent and severity of the upcoming eruption. The priority is to 

ensure the safety of aircraft in flight and there is therefore a requirement to promulgate information as a matter of 

urgency. Regardless of the extent of information available the pre-eruption phase actions should be carried out for 

every event. 

3.1.3 The initial response, “raising the alert”, commences when a volcanic eruption is expected or has occurred 

without prior warning. Initial awareness of the event can be by means of an AIREP/Volcanic Activity Report and/or 

meteorological or volcanological agencies. Arrangements in each State between designated volcano observatories, 

meteorological and air traffic management agencies shall ensure that alerting information is provided expeditiuosly by 

the most appropriate means, VA SIGMET, NOTAM or ASHTAM or re-transmitted AIREPs, to ensure safety of flight. 

3.1.4 Emphasis is placed on raising awareness of the hazard and to protect aircraft in flight. The actions are based on 

well-prepared contingency plans and standard operating procedures. Aircraft are expected to clear or avoid the affected 

area based on standard operating procedures. The alerting will trigger action, such as the collection of additional data 

and the preparation of specific safety risk assessments (SRAs). 

3.2 Originating Area Control Centre (ACC) Actions (eruption in its own flight information region (FIR)) 

3.2.1 In the event of significant pre-eruption volcanic activity, a volcanic eruption occurring, or a volcanic ash cloud 

being reported which could pose a hazard to aviation, an area control centre (ACC) 1 , on receiving information of such 

an occurrence, should carry out the following: 

a) define an initial danger area in accordance with established procedures. The size of the danger area 

should encompass a volume of airspace in accordance with the limited information available, aiming to 

avoid undue disruption of flight operations; 

1 Although the term “ACC” is used throughout this document, it applies also to flight information centre (FIC)

. 

Page 6 of 29 


i) if no such procedures have been established, the danger area should be defined as a circle with a 

radius of xxx km (xx NM) 2 . If the eruption has not commenced or if no information on upper 

winds is available, the circle should be centred on the estimated location of the volcanic activity; 

ii) should a precautionary danger area be established, its size should encompass a reasonable volume 

of airspace in accordance with the limited information available aiming to avoid undue disruption 

of flight operations; 

Note.– An area with a radius of 5 to 10 minutes flying time would result in only 2 – 3 minutes 

additional flying time. 

iii) If the eruption has started and predicted upper wind information is available, the circle should be 

centred xxx km (xx NM) 3 downwind from the volcano whilst enclosing it. The purpose of this 

initial danger area is to ensure safety of flight in the absence of any prediction from a competent 

authority of the extent of contamination; 

iv) although ATC would not normally initiate a clearance through a danger area, it will inform 

aircraft about the potential hazard and continue to provide normal services. It is the responsibility 

of the pilot-in-command to determine the safest course of action. 

b) advise the associated Meteorological Watch Office (MWO) and the appropriate VAAC (unless the 

initial notification originated from either of these entities). The VAAC will then inform the appropriate 

ACC. 

c) alert flights already within the danger area and offer assistance to enable aircraft to exit the area in the 

most expeditious and appropriate manner. Pilots should be provided with all necessary information 

required to make safe and efficient decisions while flying around the defined area. Aircraft that are 

close to the danger area should be offered assistance to keep clear of the area. Tactically re-clear flights 

which would penetrate the danger area onto routes that will keep them clear. The ACC should 

immediately notify other affected ACCs of the event and the location and dimensions of the danger 

area. It should also negotiate any re-routings necessary for flights already coordinated but still within 

adjacent flight information regions (FIRs). It is also expected that adjacent ACCs will be asked to 

reroute flights not yet coordinated to keep them clear of the danger area. It should be noted that pilots 

may make the decision not to completely avoid the danger area based on e.g. visual observations. 

d) ensure that a NOTAM/ASHTAM is originated. This must provide as precise information as is available 

regarding the activity of the volcano. The name (where applicable), reference number and position of 

the volcano should be included along with the date and time of the start of the eruption (if appropriate). 

It is imperative that this information is issued by the international NOTAM office and disseminated as 

soon as possible. 

e) in order to assist staff in expediting the process of composing the NOTAM/ASHTAM, a series of 

templates should be available for this stage of the volcanic activity Examples of VA SIGMET, NOTAM 

and ASHTAM announcing operational measures and volcanic activities in the different stages and are 

contained in Attachment K. 

3.2.2 In addition to sending the NOTAM/ASHTAM and any subsequent NOTAM/ASHTAM to the normal 

distribution list, it will be sent to the relevant meteorological agencies with the appropriate World Meteorological 

Organisation (WMO) header. 

2 The size of the area to be agreed in the region concerned. 

3 The values to be agreed in the region concerned.

3.3 Adjacent ACC Actions 

Page 7 of 29 


3.3.1 During the pre-eruption phase ATC will not normally initiate clearances through the danger area; however, 

it will inform aircraft about the potential hazard and continue to provide normal services. Any ash contamination should 

be contained within a limited area and disruption to traffic should not be excessive. Adjacent ACCs should take the 

following action to assist: 

a) when advised, re-clear flights to which services are being provided and which will be affected by the 

danger area. 

b) unless otherwise instructed, continue normal operations except: 

i) if one or more routes are affected by the danger area, stop clearing aircraft on these routes and 

take steps to reroute onto routes clear of the danger area; and 

ii) initiate a running plot of the affected area. 

4. START OF ERUPTION PHASE 

4.1 General 

4.1.1 This phase commences at the outbreak of volcanic eruption. The focus of the processes in this phase is to 

protect aircraft in flight and on aerodromes from the hazards of the eruption; to collect relevant information; and to 

combine the information available into reliable information about the volcanic cloud (horizontal and vertical extent; 

composition). 

4.1.2 In addition to relevant actions described under the pre-eruption phase, major activities of the start of eruption 

phase are: Issuance of an eruption commenced VA SIGMET; eruption commenced NOTAM/ASHTAM; and rerouting 

of airborne traffic if necessary. As appropriate, danger areas will be notified via NOTAM. This phase will last until 

such time as the ongoing eruption phase can be activated. 

4.2 Originating ACC Actions (eruption in its own FIR) 

4.2.1 The ACC providing services in the FIR within which the volcanic eruption takes place should inform flights 

about the existence, extent and forecast movement of volcanic ash and provide information useful for the safe conduct 

of flights. 

4.2.2 If necessary, rerouting of traffic should commence immediately or may be in progress if the alerting time has 

been sufficient to facilitate activation of the pre-eruption phase. The ACC should assist in rerouting aircraft around the 

danger area as expeditiously as possible. Adjacent ACCs should also take the danger area into account and give similar 

assistance to aircraft as early as possible. 

4.2.3 During the start of eruption phase, although ATC will not normally initiate a clearance through a danger area, it 

will inform aircraft about the hazard and will continue to provide normal services. It is expected that aircraft will 

attempt to remain clear of the danger area; however, it is the responsibility of the pilot-in-command to determine the 

safest course of action. 

4.2.4 During the start of eruption phase the ACC should: 

a) maintain close liaison with its associated MWO and the lead VAAC. The MWO should issue a “start of 

eruption” SIGMET message by the most expeditious means. It may simply contain information that an 

ash cloud has been reported and the date/time and location. A “start of eruption” message may also be 

promulgated by a VAA. During this phase information on the extent and severity of the volcanic event 

may be limited; however, when possible, the message should contain information on the extent and 

forecast movement of the ash cloud based on appropriate sources of information.

Page 8 of 29 


b) based on these forecasts and in cooperation (CDM) with aircraft operators and the adjacent ACCs, ACC 

measures should be devised and updated when necessary to ensure safety of flight operations. 

c) ensure a NOTAM is originated to define a danger area delineated cautiously so as to encompass a 

volume of airspace in accordance with the limited information available. 

d) ensure that reported differences between published information and observations (pilot reports, airborne 

measurements, etc.) are forwarded as soon as possible to the appropriate authorities to ensure its 

dissemination to all concerned. 

e) begin planning for the ongoing eruption phase in conjunction with the aircraft operators, the appropriate 

ACCs concerned. 

f) should significant reductions in intensity of volcanic activity take place during this phase and the 

airspace no longer is contaminated by volcanic ash, a NOTAMC cancelling the last active NOTAM 

shall be issued stating the cause for cancellation; new NOTAM/ASHTAM should be promulgated to 

update the situation. Otherwise, begin CDM planning for the ongoing eruption phase in conjunction 

with aircraft operators, the affected ACCs. 

4.3 Adjacent ACC Actions 

4.3.1 During the start of eruption phase adjacent ACCs should take the following actions: 

a) maintain close liaison with the originating ACC to design, implement and keep up to date ACC 

measures which will enable aircraft to ensure safety of flight operations. 

b) in the event that tactical measures additional to those issued by the appropriate ACC are required, the 

adjacent ACC should, in cooperation with the originating ACC and aircraft operators, impose such 

measures. 

c) maintain a running plot of the affected area. 

d) begin planning for the ongoing eruption phase in conjunction with the aircraft operators, the ACCs 

concerned. 

5. ONGOING ERUPTION PHASE 

5.1 The ongoing eruption phase commences with the issuance of the first VAA/VAG by the VAAC after 

completion of the start of eruption phase responses. The VAA/VAG will contain the current position of the volcanic 

cloud and forecasts of the expected vertical and horizontal extent of the volcanic ash cloud, and its expected movement, 

at six-hourly time-steps for the period T+0 to T+18 hours. When the volcanic ash cloud is expected to move 

considerably during a 6 hour period, VA SIGMETs for shorter periods should be produced. 

5.2 Volcanic cloud forecasts and/or VAA/VAGs may include (if available) quality indicators (e.g. accuracy, 

variability, etc.) and risk levels that can more easily be used in SRAs. 

5.3 Following the start of eruption phase, the VAA/VAG should be used to define airspace volumes encompassing 

the furthest extent of contamination predicted for that period. These volumes should be used to: 

a) publish NOTAM/ASHTAM indicating the extent of areas of volcanic ash contamination,; 

b) issue VA SIGMET warning of potential hazard from areas of volcanic ash contamination; and 

c) apply appropriate ACC measures.

Page 9 of 29 


5.4 Longer term forecasts (i.e. beyond T+6 hours) should be used to generate VAA/VAG forecasts in order to 

ensure that adequate information is available to support flight planning 

5.5 Operators should use the information published to plan their flights in accordance with their regulatory 

requirements and the service that will be provided in the airspace concerned. Operators should be aware that, depending 

on the State concerned, danger areas may be established. During this phase, operators should only operate into, above, 

below and lateral vicinity of the affected area in accordance with their SRA. 

5.6 The volcanic contamination may affect any combination of airspace; therefore, it is impossible to prescribe 

measures to be taken for any particular situation. Nor is it possible to detail the actions to be taken by any particular 

ACC. The following guidance may prove useful during the ongoing eruption phase but should not be considered 

mandatory: 

a) ACCs affected by the movement of the ash should ensure that NOTAM/ASHTAM continue to be 

originated at appropriate intervals. ACCs concerned should continue to publish details on measures 

taken to ensure dissemination to all concerned. 

b) depending on the impact of the volcanic ash, the appropriate ATFM unit may take the initiative to 

organise teleconferences to exchange latest information on the developments, in order to support CDM, 

with the VAACs, ANSPs and MWOs and operators concerned. 

c) during this phase the VAAC should endeavour to assess the vertical extent of the ash contamination and 

provide appropriate VAA/VAG to define the contaminated airspace as accurately as possible. For the 

purpose of flight planning, operators should treat the horizontal and vertical limits of the contaminated 

area to be over-flown as they would mountainous terrain. Operators are cautioned regarding the risk of 

cabin depressurisation or engine failure resulting in the inability to maintain level flight above the 

contaminated area, especially where extended range operations by turbine-engined airplanes (ETOPS) 

are involved. 

d) any reported differences between published information and observations (pilot reports, airborne 

measurements, etc.) should be forwarded as soon as possible to the appropriate authorities including 

VAACs. 

6. RECOVERY PHASE 

6.1 The recovery phase commences with the issuance of the first “No Volcanic Ash Expected VAA” which 

normally occurs when it is determined that the volcanic activity has reverted to its pre-eruption state. Consequently, a 

NOTAMC cancelling the active NOTAM, and a new NOTAM/ASHTAM, shall be promulgated to update the situation 

for volcanic ash as soon as the volcano has reverted to its normal pre-eruption status, no further eruptions are expected 

by vulcanologists and no ash cloud is detectable or reported from the FIR concerned. 

7. AIR TRAFFIC CONTROL PROCEDURES5 

7.1 If volcanic ash is reported or forecast in the FIR for which the ACC is responsible, the following procedures 

should be followed: 

a) relay all available information immediately to pilots whose aircraft could be affected to ensure that they 

are aware of the horizontal and vertical extent of the ash contamination; 

b) if requested, suggest appropriate rerouting to assist flights to avoid areas of known or forecast ash 

contamination; 

c) when appropriate, remind pilots that volcanic ash cannot be detected by ATC radar systems;

Page 10 of 29 


d) normally, ATC will not initiate a clearance through a danger area during the pre-eruption phase and the 

start of eruption phase; however, on the explicit request of a flight crew, a clearance would be provided. 

The existence of a danger area due to the presence of volcanic ash indicates the presence and extent of 

the hazard, hence ATC will inform aircraft about the hazard and will continue to provide normal 

services. It is then the responsibility of the pilot-in-command to determine the safest course of action in 

accordance with the operator’s SRA; 

e) assistance to enable an aircraft to exit a danger area in the most expeditious and appropriate manner 

should be provided; and 

f) if the ACC has been advised by an aircraft that it has entered an area of ash contamination and indicates 

that a distress situation exists: 

i) consider the aircraft to be in an emergency situation; 

ii) do not initiate any climb clearances to turbine-powered aircraft until the aircraft has exited the 

area of ash contamination; and 

iii) do not attempt to provide vectors without pilot concurrence. 

7.2 Experience has shown that the recommended escape manoeuvre for an aircraft which has encountered volcanic 

ash is to reverse its course and begin a descent (if terrain permits). However, the final responsibility for this decision 

rests with the pilot.

ATTACHMENT A - GENERAL GUIDANCE FOR THE DEVELOPMENT OF ATM CONTINGENCY 

PLANS FOR VOLCANIC ASH 4 

(This information is adapted from the Manual on Volcanic Ash, Radioactive Material and Toxic Chemical Clouds (Doc 

9691). Refer to this document for full details.) 

1. In a contingency plan relating to volcanic contamination certain steps need to be taken to provide a coordinated 

and controlled response for dealing with an event of this nature. Responsibilities should be clearly defined for the 

manager in charge, supervisors and air traffic controllers (ATCOs). The plan should also identify the officials who need 

to be contacted, the type of messages that are to be created, the proper distribution of the messages and how to conduct 

business. 

2. ATCOs need to be trained and be made aware of the potential effects if aircraft encounter unsafe levels of 

volcanic ash. 

3. Some particular points of guidance are as follows: 

a) volcanic ash contamination may extend for hundreds of miles horizontally and reach the stratosphere 

vertically; 

b) volcanic ash may block the pitot-static system of an aircraft, resulting in unreliable airspeed indications; 

c) braking conditions at airports where volcanic ash has recently been deposited on the runway will affect 

the braking ability of the aircraft. This is more pronounced on runways contaminated with wet ash. 

Pilots and ATCOs should be aware of the consequences of volcanic ash being ingested into the engines 

during landing and taxiing. For departure it is recommended that pilots avoid operating in visible 

airborne ash; instead they should allow sufficient time for the particles to settle before initiating a takeoff 

roll, in order to avoid ingestion of ash particles into the engine. In addition, the movement area to 

be used should be carefully swept before any engine is started; 

d) volcanic ash may result in the failure or power loss of one or all engines of an aeroplane; and 

e) airports might have to be declared unsafe for flight operations. This might have consequences for the 

ATM system. 

4. The area control centre (ACC) in conjunction with air traffic flow management (ATFM) units serves as the 

critical communication link between affected aircraft in flight and the information providers during a volcanic eruption. 

During episodes of volcanic contamination within the FIR, the ACC has two major communication roles. First and of 

greatest importance is its ability to communicate directly with aircraft en route which may encounter the ash. Based on 

the information provided in the volcanic ash SIGMET and volcanic ash advisories (VAAs) and working with 

meteorological watch offices (MWOs), the ATCOs should be able to advise the pilot of which flight levels are affected 

by the ash and the projected trajectory and drift of the contamination. Through the use of radio communication, ACCs 

have the capability to coordinate with the pilot alternative routes which would keep the aircraft away from the volcanic 

ash. 

5. Similarly, through the origination of a NOTAM/ASHTAM for volcanic activity the ACC can disseminate 

information on the status and activity of a volcano even for pre-eruption increases in volcanic activity. 

NOTAM/ASHTAM and SIGMET together with AIREPs are critical to dispatchers for flight planning purposes. 

Operators need as much advance notification as possible on the status of a volcano for strategic planning of flights and 

the safety of the flying public. Dispatchers need to be in communication with pilots en route so that a coordinated 

decision can be made between the pilot, the dispatcher and ATS regarding alternative routes that are available. It cannot 

be presumed, however, that an aircraft which is projected to encounter ash will be provided with the most desirable 

4

route to avoid the contamination. Other considerations have to be taken into account such as existing traffic levels on 

other routes and the amount of fuel reserve available for flights which may have to be diverted to other routes to allow 

for the affected aircraft to divert. 

6. The NOTAM/ASHTAM for volcanic activity provide information on the status of activity of a volcano when a 

change in its activity is, or is expected to be, of operational significance. They are originated by the ACC and issued 

through the respective international NOTAM office based on the information received from any one of the observing 

sources and/or advisory information provided by the associated Volcanic Ash Advisory Centre (VAAC). In addition to 

providing the status of activity of a volcano, the NOTAM/ASHTAM also provides information on the location, extent 

and movement of the ash contamination and the air routes and flight levels affected. NOTAM can also be used to limit 

access to the airspace affected by the volcanic ash. Complete guidance on the issuance of NOTAM and ASHTAM is 

provided in Annex 15 — Aeronautical Information Services. Included in Annex 15 is a volcano level of activity colour 

code chart. The colour code chart alert may be used to provide information on the status of the volcano, with “red” 

being the most severe, i.e. volcanic eruption in progress with an ash column/cloud reported above flight level 250, and 

“green” at the other extreme being volcanic activity considered to have ceased and volcano reverted to its normal preeruption 

state. It is very important that NOTAM for volcanic ash be cancelled and ASHTAM be updated as soon as the 

volcano has reverted to its normal pre-eruption status, no further eruptions are expected by vulcanologists and no ash is 

detectable or reported from the flight information region (FIR) concerned. 

7. It is essential that the procedures to be followed by ATS personnel, including supporting services such as MET, 

AIS should follow during a volcanic eruption/ash cloud event described in the foregoing paragraphs are translated into 

local staff instructions (adjusted as necessary to take account of local circumstances). It is also essential that these 

procedures/instructions form part of the basic training for all ATS, AIS and MET personnel whose jobs would require 

them to take action in accordance with the procedures. Background information to assist the ACC or flight information 

centre (FIC) in maintaining an awareness of the status of activity of volcanoes in their FIR(s) is provided in the monthly 

Scientific Event Alert Network Bulletin published by the United States Smithsonian Institution and sent free of charge 

to ACCs/FICs requesting it.

ATTACHMENT B - ANTICIPATED PILOT ISSUES WHEN ENCOUNTERING VOLCANIC ASH 

1. ATCOs should be aware that flight crews will be immediately dealing with some or all of the following issues 

when they encounter volcanic ash: 

a) smoke or dust appearing in the cockpit which may prompt the flight crew to don oxygen masks (could 

interfere with the clarity of voice communications); 

b) acrid odour similar to electrical smoke; 

c) multiple engine malfunctions, such as stalls, increasing exhaust gas temperature (EGT), torching, 

flameout, and thrust loss causing an immediate departure from assigned altitude; 

d) on engine restart attempts, engines may accelerate to idle very slowly, especially at high altitudes (could 

result in inability to maintain altitude or Mach number); 

e) at night, St. Elmo's fire/static discharges may be observed around the windshield, accompanied by a 

bright orange glow in the engine inlet(s); 

f) possible loss of visibility due to cockpit windows becoming cracked or discoloured, due to the sandblast 

effect of the ash; 

g) because of the abrasive effects of volcanic ash on windshields and landing lights, visibility for approach 

and landing may be markedly reduced. Forward visibility may be limited to that which is available 

through the side windows; and/or 

h) sharp distinct shadows cast by landing lights as compared to the diffused shadows observed in clouds 

(this affects visual perception of objects outside the aircraft). 

2. Simultaneously, ATC can expect pilots to be executing contingency procedures such as the following: 

a) if possible, the flight crew may immediately reduce thrust to idle; 

b) turn autothrottles off; 

c) exit volcanic ash cloud as quickly as possible. The shortest distance/time out of the ash may require an 

immediate, descending 180-degree turn (terrain permitting); 

d) turn engine and wing anti-ice and all air conditioning packs on; 

e) start the auxiliary power unit, if available; 

f) put flight crew oxygen masks on at 100 per cent (if required); 

g) restart engine according to aircraft operation manual procedures. If an engine fails to start the flight 

crew will try again immediately; 

h) monitor airspeed and pitch attitude. If unreliable airspeed is suspected, or a complete loss of airspeed 

indication occurs (volcanic ash may block the pitot system), the flight crew will establish the 

appropriate pitch attitude; 

i) land at the nearest suitable airport; and 

j) on landing, reverses may be used as lightly as feasible.

Page 15 of 29 


ATTACHMENT D- ACTION TAKEN BY METEOROLOGICAL WATCH OFFICES (MWO) 

IN THE EVENT OF A VOLCANIC ERUPTION 5 

1. On receipt of information of a volcanic eruption and/or the existence of volcanic ash, the MWO will: 

a) Notify, if necessary, the AFI VAAC (Toulouse) designated to provide VAA/VAG for the FIR for which the 

MWO is responsible that a volcanic eruption and/or ash has been reported. In the event that the MWO 

becomes aware, from a source other than an ACC, of the occurrence of pre-eruption activity, a volcanic 

eruption or ash from any other source , the information will be passed with all available relevant details on 

the extent, forecast movement and concentration of volcanic ash immediately to the ACC and to the 

designated VAAC; 

b) Reported differences between ash encounters by aircraft and the information published in VAA/VAG, 

SIGMET or NOTAM/ASHTAM received by an ACC shall be made available as soon as possible to the 

respective MWO, preferably in the form of an AIREP. The MWO will relay the information to the 

respective originators of the published information; 

c) Notify adjacent MWOs designated to provide SIGMET that a volcanic eruption and/or ash cloud has been 

reported, provide available relevant details on the extent, forecast movement and (if known) concentration 

of volcanic ash. In the event that any other MWO becomes aware of the occurrence of volcanic ash cloud 

from any source other than the VAAC, the information should be passed immediately to the VAAC and 

any adjacent MWO(s) downstream of the moving ash cloud; 

d) As soon as practicable, advise the ACC and the VAAC whether or not the volcanic ash is identifiable from 

satellite images/data, ground based or airborne measurements or other relevant sources; 

e) Issue SIGMET relating to the horizontal and vertical extent of volcanic ash cloud and its expected 

movement (provided in the VA from Toulouse VAAC) for a validity period of up to 6 hours. The 

SIGMET shall include an observed (or forecast) position of the ash cloud at the start of the period of 

validity, and a forecast position at the end of the period of validity. The SIGMET should be based on the 

advisory information provided by the VAAC. Include in the SIGMET distribution list the two Regional 

OPMET Databanks (RODBs) in Dakar and Johannesburg (Pretoria RODB). As well as inter-regional 

distribution, the RODBs will ensure dissemination of the SIGMET to all the VAAC, the London World 

Area Forecast Centre (WAFC) and the AFI Bulletin Compiling Centres (BCC); 

f) provide information to assist with the origination of NOTAM by ACCs and maintain continuous 

coordination with ACCs, adjacent MWOs and the VAAC concerned to ensure consistency in the issuance 

and content of SIGMET and NOTAM/ASHTAM; and 

g) provide, if possible, regular volcanic briefings, based on the latest available ash observations and forecasts, 

to ACCs, Airport Operators and aircraft operators concerned, giving an outlook for beyond T+12 hours.

ATTACHMENT E: ACTION TO BE TAKEN BY THE AFI VAAC IN THE EVENT OF A 

VOLCANIC ERUPTION 6 

1. On receipt of information from a MWO or any other source, of significant pre-eruptive/eruption activity and/or 

a volcanic ash cloud observed, the VAAC should: 

a) Initiate the volcanic ash computer trajectory/dispersal model in order to provide advisory information on 

volcanic ash trajectory to MWOs, ACCs and operators concerned; 

b) Review satellite images/data and any available pilot reports of the area for the time of the event to ascertain 

whether a volcanic ash cloud is identifiable and, if so, its extent and movement; 

c) Prepare and issue advisories on the extent, and forecast trajectory, of the volcanic ash contamination in 

message format for transmission to the MWOs, ACCs and operators concerned in the VAAC area of 

responsibility, and to the two Regional OPMET Data Banks (RODB) in Dakar and Pretoria. As well as 

inter-regional distribution, the RODBs will ensure dissemination of the advisory to all VAACs, the London 

World Area Forecast Centre (WAFC); 

d) Monitor subsequent satellite information or other available observations to assist in tracking the movement 

of the volcanic ash; 

e) Continue to issue advisory information (i.e. VAA/VAG), for validity periods T+0, T+6, T+12 and T+18 

hours after data time, to MWOs, ACCs and operators concerned at least at 6 hour intervals, and preferably 

more frequently, until such time as it is considered that the volcanic ash is no longer identifiable from 

satellite data, no further reports of volcanic ash are received from the area and no further eruptions of the 

volcano are reported; and 

f) Maintain regular contact with other VAACs and meteorological offices concerned, and, as necessary, the 

Smithsonian Institute Global Volcanism Network, in order to keep up to date on the activity status of 

volcanoes in the VAAC area of responsibility.

ATTACHMENT F - PROCEDURES FOR THE PRODUCTION OF MODELLED ASH CONCENTRATION 

CHARTS 

1. The following procedures are to be applied by the meteorological office of a Provider State, having accepted, by 

regional air navigation agreement, the responsibility for providing a VAAC within the framework of the International 

Airways Volcano Watch (IAVW). 

2. All VAA and VAG information issued by a meteorological office under designation as a VAAC within the 

framework of the IAVW shall be prepared in accordance with ICAO provisions. 

3. Additionally, where feasible, the meteorological office may issue modelled ash concentration charts and 

corresponding coordinate data files at 6-hourly intervals showing the different ash concentrations for the validity periods 

T+0, T+6, T+12 and T+18 hours after data time. These charts will show forecast ash distribution in terms of Areas of 

Low, Medium and High Contamination and be published at the same time, and with the same validity periods, as the 

VAA/VAG described above. Updated charts and data files should be distributed prior to the end of the validity time of 

those previously distributed. 

4. These data may be used by Provider States to prepare SIGMET, NOTAM/ASHTAM and to establish Danger 

Areas as appropriate.

ATTACHMENT G RECOMMENDED ACTIONS BY STATES OF THE OPERATOR/REGISTRY WITH 

REGARDS TO AIRCRAFT OPERATIONS IN THE EVENT OF A VOLCANIC 

ERUPTION 

Safety Risk Assessments For Flights In Airspace Proximate To Volcanic Ash 

1 Introduction 

1.1 It is recommended that States of the Operator/Registry as appropriate which intend to allow operators under 

their jurisdiction to operate in areas of volcanic ash contamination consider requiring operators to carry out a 

safety risk assessment prior to carrying out such operations. 

1.2 Safety risk assessments should be completed prior to planned operations in airspace or to/from aerodromes 

which may be contaminated by volcanic ash. 

2 Applicability 

2.1 All operators conducting flights in airspace and/or to/from aerodromes which could be affected by volcanic ash. 

3 Recommendations 

3.1 In accordance with ICAO Annex 6, Chapter 3, paragraph 3.3- Safety Management, it is recommended that 

States of the Operator/Registry as appropriate require all operators, planning to operate in areas where the 

presence of volcanic ash is forecast, to carry out a safety risk assessment prior to planned operations. The safety 

risk assessment should include a requirement for the operator to: 

a) Conduct their own risk assessment and develop operational procedures to address any remaining risks; 

b) Put in place appropriate maintenance ash damage inspections; and 

c) Ensure that any ash related incidents are reported by AIREP and followed up by a Volcanic Activity Report 

(VAR). 

3.2 Guidance in the preparation of such a safety risk assessment is provided in Attachment H of this document.

1 Introduction 

Page 19 of 29 


ATTACHMENT H EXAMPLE SAFETY RISK ASSESSMENT PROCESS 

1.1 The safety risk assessment process is described in the Safety Management Manual (Doc 9859) .The process 

involves identifying the hazards associated with the activity (in this case airspace proximate to volcanic ash or 

flying to and from aerodromes affected by volcanic ash), considering the seriousness of the consequences of the 

hazard occurring (the severity), evaluating the likelihood or probability of it happening, deciding whether the 

consequent risk is acceptable and within the organisation’s safety performance criteria (acceptability), and finally 

taking action to reduce the safety risk to an acceptable level (mitigation). 

2 Hazard Identification 

2.1 A hazard is any situation or condition that has the potential to cause adverse consequences. A suggested list of 

topics, that is not necessarily exhaustive, to be considered is attached at Attachment I 

3 The Safety Risk Assessment 

3.1 Risk is an assessment of the likelihood and the severity of adverse consequences resulting from a hazard. 

3.2 To help an operator decide on the likelihood of a hazard causing harm, and to assist with possible mitigation of 

any perceived safety risk, all relevant stakeholders should be consulted. 

3.3 The safety risk from each hazard should be assessed using a suitably calibrated safety risk assessment matrix. An 

example risk assessment matrix is given in Safety Management Manual (Doc 9859) but an alternative which 

aligns with an organisation’s own Safety Management System (SMS) would be equally appropriate. The safety 

risk should be derived by considering the severity of the safety outcome arising from the hazard, together with the 

likelihood of the outcome. 

3.4 The severity of any adverse consequences resulting from a particular hazard should be assessed using a suitably 

calibrated severity scale. Example scales are given in Safety Management Manual (Doc 9859) but an alternative, 

which aligns with an organisation’s own SMS, would be equally appropriate. Note that, for any flight, the safety 

outcome of a volcanic ash encounter may be significant. 

3.5 Risk Likelihood 

3.5.1 The likelihood or probability of adverse consequences resulting from a particular hazard should then be assessed. 

The likelihood should be agreed using a suitably calibrated likelihood or probability scale. An example 

probability scale is given in Safety Management Manual (Doc 9859), but an alternative which aligns with an 

organisation’s own SMS would be equally appropriate. 

3.5.2 When assessing likelihood or probability the following factors should be taken into account: 

• The degree of exposure to the hazard. 

• Any historic incident or safety event data relating to the hazard. This can be derived from data from industry, 

regulators, other operators, Air Navigation Service Providers, internal reports etc. 

• The expert judgement of relevant stakeholders. 

3.5.3 The results of the assessment should be recorded in a hazard log, sometimes referred to as a risk register. An 

example of a hazard log is at Attachment J.

3.6 Risk Tolerability 

Page 20 of 29 


3.6.1 At this stage of the process the safety risks should be classified in a range from acceptable to unacceptable. A 

suitable set of definitions for Risk Classification is given in Safety Management Manual (Doc 9859). 

3.6.2 Appropriate mitigations for each identified hazard should then be considered, recorded on the hazard log and 

implemented. Mitigations must be adopted in order to reduce the safety risks to an acceptable level, but additional 

mitigation wherever reasonably practicable should also be considered where this might reduce an already 

acceptable safety risk even further. Thus, the mitigation process should reduce the safety risk to be as low as 

reasonably practicable. 

3.6.3 Not all hazards can be suitably mitigated in which case the operation should not proceed. 

3.7 Mitigating Actions 

3.7.1 Mitigating actions by themselves can introduce new hazards. Where an organisation has an effective SMS then 

procedures will exist for continual monitoring of hazard, risk and involvement of qualified personnel in accepting 

the mitigating actions or otherwise. Operators without an effective SMS should repeat the safety risk assessment 

following any mitigation process and at regular intervals as the circumstances on which the original assessment 

was predicated may have changed. This ensures ongoing safety management or monitoring. 

3.8 Records 

3.8.1 The results of the safety risk assessment should be documented and promulgated throughout the organisation and 

submitted to the operator’s national safety authority. Actions should be completed and mitigations verified and 

supported by evidence prior to the start of operations. 

3.8.2 Any assumptions should be clearly stated and the safety risk assessment reviewed at regular intervals to ensure 

the assumptions and decisions remain valid. 

3.8.3 Any safety performance monitoring requirements should also be identified and undertaken through the 

organisation’s safety management processes.

(This list is not necessarily exhaustive.) 

Any actual or suspected volcanic ash encounter will require a tech log entry and 

appropriate maintenance action prior to subsequent flight. 

Penetration (detail and duration) of airspace or operations to/from aerodromes 

which may be contaminated by volcanic ash will require a tech log entry. 


Maintenance Procedures 

Operators, who are operating in areas of ash contamination, are recommended to 

enhance vigilance during inspections and regular maintenance and potentially 

adjust their maintenance practices, based upon the observations, to prevent 

unscheduled maintenance. Observations should include signs of unusual or 

accelerated abrasions, corrosion and / or ash accumulation. 

Operator co-operation is requested in reporting to manufacturers and the relevant 

authorities their observations and experiences from operations in areas of ash 

contamination. If significant observations are discovered beyond normal 

variations currently known, manufacturers will share these observations, and any 

improved recommendations for maintenance practices, with all operators and the 

relevant authorities.

requirements for WAFS forecasts to be provided by WAFC [London, Washington]. 

[WAFSOPSG Conclusion 1/2] 

2. For back-up purposes, each WAFC should have the capability to produce WAFS forecasts for 

all the required areas of coverage. [WAFSOPSG Conclusion 5/2] 

3. WAFS forecasts should be disseminated made available by WAFC [London, Washington] 

using the [satellite distribution system for information relating to air navigation (SADIS), 

international satellite communications system (ISCS1, ISCS2)] covering the reception area shown in 

FASID Chart CNS [4] or using the satellite and Internet service. [WAFSOPSG Conclusion 5/2] 

Editorial Note.— Insert “or using the [SADIS, ISCS FTP WIFS service” in the corresponding CNS 

procedure contained in Part IV of the ANP. 

4. Each State should make the necessary arrangements to receive and make full use of 

operational WAFS forecasts made disseminated available by WAFC [London, Washington]. The lists 

of the authorized users of the [SADIS, WIFS ISCS1, ISCS2] services in the [AFI, ASIA/PAC, 

CAR/SAM, EUR, MID, NAT] Region[s] and the locations of the operational VSATs and FTPs are 

available from the following websites: 

• www.icao.int/anb/sadisopsg (click “Operational Information” and then “Status of 

implementation”) for SADIS; 

• www.weather.gov/iscs (click: “Documents” and then “Status of implementation of
