I am going through a Citation recurrent this week. Evidently the pilot was a seventy year old, single pilot qualified, reported auto pilot difficulties. It would have to be some kind of hardcover and failure to disconnect. There are a couple disconnect features on the autopilot, but there has been another autopilot disconnect mishaps many years ago.
Thanks for the follow-up! Last night at an early dinner, I was telling my wife about your posts and background.....
BTW, proudly served with VFP-6366.....
