X-Plane Autopilot Questions & Answers

This hub covers X-Plane autopilot behaviour, from VNAV that refuses to engage to unexpected disconnects in X-Plane 12. It explains the conditions behind active and armed modes, flight-director indications, route and altitude constraints, and approach capture, helping distinguish incorrect setup from aircraft limitations or simulator faults.

Guidance also addresses the practical differences between desktop and X-Plane Mobile, including safe disengagement in aircraft such as the C172. For add-ons such as the FlightFactor A350, the focus includes remaining too high on RNAV approaches, checking descent preparation, navdata and mode sequencing rather than simply forcing the aircraft down. Answers are written and tested by the Fly Away team where the relevant aircraft and platform permit.
