I’ve also noticed this strange behavior of the autopilot in free flight mode. It happens when the engine is at full throttle: the plane climbs and descends, it oscillates on its own…

however, I’ve noticed that by slightly reducing engine power, the autopilot functions normally again and stabilizes.

So, full throttle = the plane climbs and descends / slightly reduced engine power = normal behavior.

This is another problem, please make a separate post. I’m talking about broken autopilot behaviour when activating it from level flight at normal speed (120/130 kts) with the intention to go into attitude hold. I see it extremely often in career mode. I suspect a bug in the elevator trim logic where autopilot works with an faulty offset of the value where elevator trim is really at.
