I have created a mission in single player, there I coldstart the hornet on a carrier, take off, and take out some moving vehicles, land on a Airport "jump in" in a Turkish Cobra, and take out some infantry insurgents, and after that, I go back to the Airport and "jump in" the hornet.
But when I "jump in" to the hornet, to fly home to the carrier, the hornet does not start, because the APU shut down after a few seconds, when I try to coldstart the right Engine (right-shift +home). I have also tried "quickstart" (left-win + home) but that not work, the APU goes off after a few seconds. I have Combined Arms, and I play as a Commander, and I have "checked" "player can drive" and "pilot can control vehicles".
