How can I turn on the second screen (the right side screen) on the c400? All the master switches are on. Is that why I cannot engage autopilot?
Try pressing the far right function button on the Garmin that worked for me on the 208B.
let me know if it worked.
I skipped ahead to descent because I wasn’t wanting to hand fly for an hour and it turned on and AP works. If I have the same issue again I’ll try it.
