Probably a dumb question, but I’ll be installing a GMU 11 in the aft deck (under the horizontal stab) of my RV9A as is commonly done. The Garmin installation instructions state that the GMU 11 must be within 3.0 degrees of “level in-flight cruise attitude”.
Is there any trick to ensure that I’m within the required 3.0 degrees since I don’t know how the aircraft attitude on the ground compares to its in-flight cruise attitude.
Many thanks!
Mike
