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.

Subject: RV8-List: GRT AHRS Pitch & Roll Calibration...
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!
