Does  anyone know how to get the ground power for the 757 or does captainsim need to update this part as well when they update the ACE program for Captainsim 4.4.. I haven't figured out how to get the grnd power.. I think they need to possibly do an update for this as well when they update the ACE program maybe they can do an update to give the availability to get grnd power at the gate.  Most Airlines now its recommended unless your doing a real quick turn to not run the APU unless necessary because of fuel cost but to run off of GPU until closer time for departure then turn on the APU & disconnect the GPU & run off of APU until engine start...
