I can only repeat and confirm, if you see simulated passengers ( boarding fast, no passengers visible ), it's because GSX hasn't detected the jetway to be docked or hasn't detected the jetway at all, which can happen for the following reasons:
- If it's a 3rd party airport, it hasn't been disabled in the GSX Config panel.
- If you are sure it's disabled, the jetway hasn't docked, because it couldn't from that position
- If the jetway has docked, GSX cannot detect if it has, unless it has a working "hood" (the jetway cover) animation, which is the method GSX uses to know if a jetway docking, since nothing in the SDK explicitly tells if a jetway has docked, or where.
- There's a bug in the SDK Simconnect call that returns the scenery objects in a scenery, which (for jetways *only*) has a bug that, unless you ask for ALL objects in a 20Km range around the airplane, it won't return any jetways, if it wasn't for this bug, we would obviously only search for objects fairly close to the airplane, like in a range of 150-200 mt at most but, because of that bug we need to call in a 20km range, if the scenery contains lots of objects, the call might take longer and/or not returning data or might get stuck, so you need to RESTART COUATL before docking the jetway.
