Reject Auto Mission


I’ve been developing my first fixed wing autopilot system. The stabilised flight mode was working perfectly. After uploading a mission to the aircraft (simple waypoint following, attached)

we completed a manual take-off, then attempted to start the auto mission, however the QGroundControl rejected the automission.

I’m struggling to upload the log file but there’s nothing obvious standing out in it. Does anyone know any reason why the mission would be rejected?

Thanks in advance
