Hello,
We have an AFS 5800T in an RV10. We are experiencing an issue with the AHRS. We were flying today and began receiving messages concerning the AHRS being offline, specifically a big red box saying "AHRS OFFLINE" ... I have attached a screenshot of the screen during the issue. I apologize for it being blurry, it was a bit bumpy out there today.
Basically, the issue surfaced just after we had disengaged the integrated Advanced autopilot that was flying a coupled (GTN 650) Nav/VPTH route. The message would appear on the screen for 3-5 seconds (X-ing out all of the instruments) and then everything would come back online for about 10 seconds. Then the cycle would repeat. This went on for about 10 minutes. We stopped seeing the issue about 5 minutes before landing. However, upon taxiing back to the hangar, the issue and cycle began to occur again, all the way until shutdown.
The system and airplane have approx. 100 hours. We also have an AFS 4500 and GRT Mini-X.
We do fly the airplane IFR and in IMC, so this issue is a bit disconcerting, even though we do have more than adequate backup. What could be causing it? Any help would be greatly appreciated!
