Hi,
Thanks for the update, starting the engine(s) before pushing back is really great and helps to simulate more real operations but I have a doubt. Let´s say that I have the APU inoperative and I need to start one engine on the parking and after the push back I start the second engine with the cross bleed start procedure. To start the engine on the stand I need the GPU connected however GSX doesn´t allow me to do so, it always asks me to disconnect the GPU.
Thanks,
Francis
