Can you "topple" a Direction Indicator?
Just been to Alderney Fly-In and took part in the Navex. There was a timed start over a farm just inside the French Coast. Arrived well-early and weaved and weaved and made multiple slow orbits (in both directions) before running in to get the timed start right. Then horror - DI wasn't responding at all. Just didn't move in response to any turns, even though I had suction. Did the course flying the map (more than the compass), and the DI was U/S. Started the aircraft a day later, flew home, and it's working fine. I know you can upset an AH, but can you do the same to a DI, as its also a gyro mechanism? Should I be worried about future working of the instrument?
