Compass stuck restart aircraft. It’s sitting in the yard about 20 yards from the house which my normal home spot. Yes it is still there when I walk away. I tap on the top of the AC and restart. It rarely does it twice in a row. It has happened in flight twice. I went out and started her up and of course no warning. It’s beginning to drizzle rain a bit. When it clears I’ll try to reproduce the error message again. Thanks
