Matt, On the Settings Menu/Primary Flight Display there is a "Pitch Ladder Offset " that can be adjusted to +- 15 degrees. There is no adjustment for roll.- GRT states that the AHRS and magnetomet er must be installed level in roll, and I believe this is critical for stab ility.- If your mounting shelf isn't perfect, use shims between the mount ing flange and your mounting bracket to get it level.- You'll also want t o make sure that your mounting brackets won't flex under "G" and vibrate fr om engine vibrations.

How do I adjust the pitch and roll calibration of the AHRS on the Grand Rap ids EFIS HX AHRS? I go into the AHRS Maintenance page and find the Pitch and R oll numbers for AHRS 1 and for AHRS 2, but when I select "Change", but none of the numbers are adjustable. I mounted my dual AHRS as level as I possibly could, but there's no way a mere mortal such as myself could possible get it perfect. Surely you are allowed to dial in the pitch and r oll attitudes........? Thanks for the help!
