After 250 hours of perfect performance, my D100's artificial horizon decided to do slow rolls (360 degrees in about 30 seconds). Runup and take off were completely normal. About 5 minutes into the flight the slow rolls started. I tried powering off and on several times and it made no difference. Since it was a beautiful, clear day, we just continued on.
After about an hour of slow rolls, the rolling stopped and after about 5 minutes, the horizon and heading were back to normal and for the remainder of the flight (~1 hour), everything worked perfectly again. We stopped and got gas (off for ~15 minutes) and headed home - again it worked perfectly.
I'm running a D100 with version 5.4. This wasn't a critical problem in clear air, but in marginal conditions, it would have been very disturbing!
Any ideas? Sun spots? Lightsquared's new network? Secret Service jamming (Obama will be in town tomorrow)? Or do I just have a sensor that is going bad? Thanks for any ideas!
