Hell, the theroy is that Eastern Airlines flight 401 crashed because
the Captain bumped the yoke while just turning to talk to the copilot
and didn't know he had changed modes. *It happened.


I cannot see how you wouldn't know the autopilot has been disconnected
as there is a very loud audible warning when this occurs as well as a
warning master switch above the PFD that the pilot cannot miss on
737/747 aircraft and I'm sure Airbus have it too
