Yesterday I was in solid IMC coming from PMP to RYY when my AFS 4500 AHRS quit for about 5 mins. It started tumbling like a failed gyro. Luckily the plane (RV-10) has 3 independent AHRS and 3 screens so it was really a non event. However, I did notice that my AFS pilot, which was in efis mode at he time, went down with it, so I had to hand fly the plane.
My question was that I thought the AFS autopilot(really a trutrak) was slaved to the GPS and not the AHRS. My other question was, if I had put the AFS pilot in AP mode rather than EFIS mode, would it have held the headings and altitudes.
BTW, after about 5 mins of straight and level, the AHRS re erected itself and the flight home was uneventful( with the exception of dropping temps and having to descend to stay the heck out of the icy clouds)
