When you start GSX, it will place all Carts and equipment around your airplane. That's what it is intended to do. So if you don't want to see it, you have to curstomize the stand you are and move them further away (out of sight). But that will affect the stand also when you arrive. There is no difference between arriving at the airport and departing. it could be that you do a turnaround, then everything will stay in place. GSX does not know if you arrive or depart when you start it up. that is also realistic, because at an airport you always will have some stuff around your airplane, even when departing.
