Everything is going well at the start. Speed, altitude and heading are in “managed” position. Suddenly, the speed continues to rise beyond 250 and the AP disconnects, without the possibility of putting it back into service.
This problem is delusional. On the runway, in the dashboard, the three points are on: speed 290, altitude 15,000, feet while self-managed. Take off, throttle on CL. Switching on the PLC. The plane climbs normally. Suddenly, the AP disconnects, I cannot put it back on. The speed exceeds the limit and locks into 360 and the altitude is not respected. I manage to reconnect the AP, but it immediately hangs up. Ditto if I reduce the speed to 290 and the altitude does not return.
Speed should be managed showing - - - on the display, not 290, and A/THR should be ON when you put the throttle in CL.
