I definitely have seen compass redundancy switch message on my Mavic Pro, and have uncommanded ATTI switch once at night taking off from the roof of my car. My car is mostly aluminum and has a glass roof, so it usually works ok but just not that night. It regained GPS mode after maybe 10 seconds.
Back in the day, I had my phantom 2 almost flew away. In GPS mode and then it glitched, took off sideways uncommanded as fast it could. I had to jam on the throttle to have it climb to avoid clipping a house and then flicked it into ATTI mode myself to regain control. Not sure what happened then.
Perhaps haveing dual compass allows the drone to recognize when something is wrong (compass don’t agree) and drop you into ATTi mode as opposed to trusting a bad compass and fly away.
I wis Mavic has a manual ATTI mode switch.
I never had an IMU error in flight but I could imagine it would be a lot worse. And here is no manual mode anymore since P2 to give you a chance to save it.
