Comet Jetliner

  • Hi,

    I've just purchased the Comet Jetliner and as part of trying to fly it, i'm starting off by shutting the engines down on the ramp and loading up using GSX. But i have a problem that despite being on ground power (IE once i've turned the fuel cocks off and then switched the built-in ground power toggle) the avionics go off and i can't start the aircraft.

    Can anyone tell me how to get round the seeming running out of battery/ground power not actually supplying issue?
