We had to mark all parking as GA, to get rid of all default ground vehicles.
We are going to fix this with GSX, because in GSX parking list we can override and redefine every parking name listed in the AFCAD as we please, and we can regroup into easier to understand groups, like "Terminal 1", "Tom Bradley", etc. Just look at the parking selection menu in GSX.
We are working on a new feature in GSX, that will allow to call that menu in every situation, to simply move your airplane without having to use the "Go To Airport" menu and without necessarily activate the parking with GSX.
