It's not on the longitudinal axis (you installed it off-center)? Does that cause any roll issues on the artificial horizon?

Mine is forward of the instrument panel, essentially over the right knee. Transponder and radio "guts" are not on that side. It appears to work fine there. Have not flown much IFR with it but appears the AHRS is fully functional.

A note that closing the canopy (if the instrument panel tilts with it) immediately after power up helps the Air S calibrate. Look for the three dots in the upper R of the AHRS display prior to launch. Without at least one (prefer two) dots, you won't get the sort of wind reporting the Air is famous for.

At the moment (could be fixed with software) if you're at a contest that demands disabling the AHRS the entire funtionality of the ISU is lost, seriously compromising the vario.
Had originally thought the AHRS screen would be the only loss.
I will send an e-mail to Air support about this.
