Ted:
<<AHRS mounted in rear bulkhead area...>>

I have the 2 screen SFS in my IV-P. AHRS is mounted on the forward main spar shear panel. This is the center of roll and pitch on the IV-P. The delicate accelerometers in the AHRS depend on this optimum position, in my opinion, and that of Sierra Flight Systems. How does it work back there? Pitch excursions (G loads) must send the primary flight display horizon wildly up and down. Good luck,

Tony Durizzi
