Rob,
Sunday I was flying some practice approaches with my 4500/AP autopilot/430w equiped glasair. I flew the missed and the a/p sequenced us into the missed approach hold. after one lap of the hold the ap disengaged without warning. This is not the first time the ap has inadvertently disengaged. I've not yet figured out what is triggering this disconnect, but is it possible to have an aural warning of a change in a/p status, something like "autopilot disengage", "autopilot engage"? Even just "autopilot" if it goes on or off?
Thanks,
CA
