What I mean by interfering with GSX is the GSX ground service. When a King Air gets assigned to a gate with a jetway, GSX ground service like deboarding, boarding, does not happen, you get a message telling you it's happening and you can't see it happening.
GSX ground service at a small or medium ramp you can use deboarding and boarding does happen and you can see it. A staircase rolls up to the aircraft and animated passengers deboard and get into a waiting van which then leaves. That does not happen at a gate with a jetway. So my question is, if ATC or ground assigns you to a gate with a jetway, and after you have parked there, can you then use GSX to reposition your King Air to a ramp in order to use GSX ground service.
