A general interest question really.
Does anyone know why the AFS 3500 magnetometer has to be aligned with the EFIS in all three axis rather than be aligned with the aircraft axis. Of course the roll and yaw axis are the same for the aircraft and the EFIS, but the pitch axis of the EFIS in the instrument panel on my RV7 and the aircraft pitch axis are different by several degrees. I would have thought that the EFIS wanted to know the actual pitch axis of the aircraft for the Artificial Horizon display rather than the angle of the panel?
Just displaying my ignorance!
