Certified G5 Attitude Indicator Cannot be Adjusted by the Pilot

Older attitude indicators could be adjusted to compensate for parallax error based on the viewing angle of the pilot.  Since the G5 is a digital screen, there is no parallax error, so the FAA has mandated that we cannot allow the pitch to be adjusted by the pilot. 

If your certified G5 does allow for pitch adjustment, then it is not compliant with Garmin’s STC.  The standard used by Garmin to determine compliance with 14 CFR part 23 for flight and navigation instrumentation in aircraft states “If an attitude display is installed, the instrument design shall not provide any means, accessible to the flight crew, of adjusting the relative positions of the attitude reference symbol and the horizon line beyond that necessary for parallax correction.”

It is expected for aircraft to fly at different attitudes, even when flying straight and level.  This is mostly based on your aircraft’s weight and balance, power setting, and speed. 

If you are concerned about your certified G5 attitude indication in flight, please see a Garmin Dealer.
