Controllers are required to complete the ATIS information and tune to the correct frequency before connecting to the server.
In the event that there are no further upper ATC facilities available, controllers shall instruct pilots to switch to UNICOM on the frequency 122.800 MHz.
Due to the low volume of traffic at Ubon Ratchathani Airport, Ubon Ground will be responsible for handling the delivery clearance for departing aircraft.
All IFR aircraft are to call “Ubon Ground” 5 minutes prior to start up request for ATC clearance.
- After a Pilot has requested ATC Clearance to destination, Controller shall check, if following information in flight plan are filled correctly:
a. Flight rules
b. Equipment
c. SID and Route
d. Requested Flight Level
e. Destination Aerodrome
f. EET and Endurance
- Controller shall give appropriate ATC clearance with following information:
a. Callsign
b. Destination Aerodrome
c. Flight Level
d. SID and Route
e. Initial Climb (11,000 ft)
f. Transponder Code
g. NOTAMs (If Required)
NOTAMs: NOtice To AirMens.
SIDs: Standard Instrument Departures.
STARs: STandard Arrival Routes.
