    What is AHRS SB??

    Hi Rob

    After 2 weeks of IFR weather, I went out today in my RV-7 to dust off my rusty piloting skills. I was doing a series of steep turns in quick succession and when I rolled out, the attitude indicator on my AFS-4500 showed about a 10 degree bank. Experimenting, it would not show level after rolling out of a steep turn for about 30 seconds. Digging into the AHRS settings menu, I discovered an item I never noticed before: SB. It was set to MEDIUM. I played around with the other settings and when I set SB = FAST, the attitude indicator aligned fine after rolling out from a steep turn. SB=SLOW made it worse. What am I changing???

    It is the slip ball filter, it should not have any affect on AHRS performance.

    Hmmm.. Interesting. Maybe it was my imagination!! I'll play with it again next time out.
