Is there any possibility to tell GSX which Logo and Tag should appear on the ULDs with the FSL A320 in P3D V4?
That would be very cumbersome, because the GSX airplane configuration is related to a single airplane folder with multiple liveries sharing the same configuration, and rightly so, otherwise you would have to configure each and every single livery variation for GSX, which wouldn't make any sense, since different liveries of the same airplane model surely share *everything* that matters to GSX, like the doors position or the engine positions.
Wouldn't be easier to ask FS Labs to just include the atc_parking_codes in their liveries ? It's part of the SDK standard after all and it's there precisely to have a sure way to identify different airline of the same airplane model.
This airline_iata_code is not standard and GSX respect the SDK, so it uses ICAO airline codes for the operators which are airline, same as the sim so, even if GSX read that one, it still won't work, unless we added some kind of conversion from IATA to ICAO.
Way easier, cleaner, and 100% standard SDK, if the aircraft.cfg contained the atc_parking_codes, in their proper format, which is ICAO.
