Is there a way to get the cargo doors to open automatically when the baggage loader arrives the way the main exit opens when the jetway is docked? Same with catering trucks.
That's exactly what GSX does already. Provided, of course, the airplane uses standard doors and those are correctly set in the airplane profile. Since you haven't said which airplane you use, it's not possible to know if this is not happening:
- Because the airplane you used use standard doors, but they are not set to the correct codes:
OR
- The airplane you used use non-standard doors, so it requires custom coding from GSX
OR
- The airplane use its own GSX integration, so it's not opening the cargo doors for some reason, assuming it was programmed to do so.
