beechcraft king air 350i AI Cold start single engine work 
I would start it. Didn’t think the AI controlled the play that much other than taxi, takeoff, cruise, descent, land, and taxi in.
See if starting it first works then do the AI and see what it does
Thank you for replying, I am a novice, I hope AI can control everything haha.I will try to start the plane and try AI again。
