Not sure whether this is a new issue in the alpha release, or an old one. I find that the King Air AP disconnects often, for no apparent reason. I'll be flying along quite happily in say HDG and ALTS mode with AP engaged, when suddenly it changes from AP to FD (flight director) mode. One possibility is noise on my joystick control inputs, since I notice that the AP disconnects if you give manual control inputs. Even though I'm not touching the joystick, it is possible that noise makes the AP think I'm giving manual control inputs, and disconnects. Any other ideas, or suggestions how to prevent this from happening?
