This GSX profile contains the customization of all the gates and ramps (I didn't do the parking position). As usual, for each gate, I also set up the pushback track named after the runway you will take for take-off.

Please note that I used the scenes below to customize the GSX profile. So many thanks to Polish Cities and PG_Simulation for their work.

One more thing, you must avoid gates 47, 48, 53, and 54 cause GSX gives an error saying that those parking are isolated.
