Hi folks,
Flying a 2007 M20TN G1000.
Was out flying yesterday and all of a sudden my AHRS reset/rebooted in flight. During the time it was offline, I lost traffic data during this time, too. Would be offline for maybe 1-2 minutes then it came back and everything was fine. Would fly for 3-4 more minutes and then happen all over again. Noticed in the LRU system page that it was the GDL 90 that had a red x on during the time it was failing, though for a brief few seconds I saw the GMU1 and GRS1 have red X's as well. Pulled the SDCARDs out and they confirm the loss of data during the period when the AHRS reset and lost traffic data.
Attached photos of it when I had it plugged in the hangar (GPS probably wouldn't work), so that should be expected. Easily reproducible.
Curious if anyone has seen similar before? I've browsed on the Internet and have heard of posts about maybe the magnetometer needs to be re-calibrated.
