The mission switched between multicopter and fixed-wing flight

InformationPlane: take-off, landing, QuadPlanePlane only

What ArduPilot says:

In AUTO a DO_VTOL_TRANSITION command (a mission item, or a command from the ground station) changes how the mission is flown. “Entered VTOL mode”: from here the waypoints are flown on the lift motors, like a multicopter. “Exited VTOL mode”: back to flying on the wing, with a transition. Q_ENABLE 2 starts every AUTO in VTOL mode.
