3.5-inch color display which is sized to fit in a standard 3-1/8-inch instrument cutout. When installed as part of a G3X system, the G5 provides a redundant source of attitude and air data to the G3X displays, and additionally provides backup autopilot control allowing coupled GPS approaches to be flown or continued in the event of primary flight display is unavailability.
During system initialization, the G5 displays the message ‘ALIGNING’ over the attitude indicator. The G5 should display valid attitude typically within the first minute of power-up. The G5 can align itself both while taxiing and during level flight. G5 Electronic Flight Instrument Pilot's Guide for Non-Certified Aircraft...
Any failure of the inertial sensors results in loss of attitude and information (indicated by Red-X flags over the PFD attitude display). If the G5 senses that the attitude solution is valid, but not yet within the internal accuracy limits, "ALIGNING" is displayed. The G5 can align itself both while taxiing and during level flight.
Magnetic heading is available in a standalone installation with a magnetometer, and when the G5 is configured as a backup in a G3X/G3X Touch system and the G5 is receiving magnetic heading data from an ADAHRS unit. If magnetic heading input data is not available, the G5 will display GPS-derived ground track instead.

Vspeed references including V , can be configured to display on the G5, refer to the Installation Manual section for more information. When airspeed is present, the Vspeeds configured are displayed at their respective locations to the right of the airspeed scale, otherwise the Vspeeds are displayed at the bottom of the airspeed indicator.
