hello,in the checklists I read that after starting the engines I have to shut down the APU. But when I do that I can no longer activate the auto-throttle. What am I doing wrong?Sander

Sander -What you are doing wrong is that you are not setting up your electrical systems correctly. You need to have the engine driven generators online/connected to the buses.(4789)Hope it helps,

Turn on the two toggles on either side of the APU switches.Terry

thanks for the help, now I can finally shut down the APU inflightSander
