You need to stop engines to request ground services

An added feature needed is "start engine at the gate" - to account for times when the APU has failed/bleed INOP, and we're starting with external pneumatics. Trying to request pushback before I start and then starting doesn't help.

It's a feature we had from years in the airplane profile, page 75 of the manual:

Engines Start before Pushback

If this option is Enabled, GSX will wait for at least one Engine to start before starting Pushback. It’s normally used only with airplanes without an APU.

It was originally designed for planes like the Concorde that don't have an APU, but can be also used to simulate a possible APU failure.

ah so I'd have to edit the aircraft GSX config... It looks like this option, while great for concorde, wouldn't work for normal ops- when the APU is working. Can you add an option to ignore the engine state when pushback is requested, under all conditions?
