The current G5 STC relies on standard scan instruments being installed to assist in the unlikely event of a G5 failure. The certification requirements for primary vs. standby are different and rely on EFIS certifications. Also, the G5 is a PMA approved part not a TSO approved part.

The G5 electronic instrument is capable of operating as a primary attitude indicator, DG or HSI.


The STC approves the installation of the G5 in an existing instrument panel. In the attitude application, the G5 can replace an existing vacuum attitude indicator or rate-of-turn indicator. The G5 can also replace existing vacuum driven DGs or existing HSI, either standalone or in combination with a G5 attitude display. 

The G5 is designed to be installed into a standard 3” instrument hole in place of existing indicators . Other primary flight instruments remain in their current approved locations. Please note that the G5 cannot replace an existing primary attitude indicator that has a Flight Director. However, if the existing attitude indicator is interfaced to the autopilot and it does not include Flight Director, the existing attitude indicator can be moved to the rate of turn indicator location and G5 installed as the primary attitude indicator. Also, for installations that do not install a G5 as the replacement primary attitude indicator, the G5 can be installed as a second attitude indicator in place of the existing rate of turn indicator. However, if the existing rate of turn indicator is interfaced with the autopilot, it cannot be replaced by a G5. The G5 can only be installed in the locations specified in the STC. It is an installer’s responsibility to ensure the installation limitations are considered prior to modifying an aircraft.

Yes in November 2017, Garmin released a PMAd flush mount adapter plate for either single or dual installations. Part Number for ordering is 115-02733-00.  List Price is $99.95.


As of September 2017, the Garmin G5 electronic flight instrument is not a replacement for the KI-256 flight command indicator. 


The DG/HSI version of the G5 can interface to a variety of autopilots such as the King KFC-150/200 to provide heading and course error to the autopilot.  The G5 can interface to select autopilots for coupled flight in heading and nav modes with a compatible navigation source.

well.  The KI-256 is not simply an attitude gyro/indicator.  It supplies attitude data to KFC autopilots and is a flight director as well.

For the G5 DG/HSI version with nav interface (PN K10-00280-30), only Garmin nav/GPS radios will interface to the G5.  This includes the Garmin GNC-255 series, SL30, GNS-430/530 series, and GTN-650/750 series navigators.

As of June 2017, the G5 has not been approved as the standby instrument in the G1000 cockpit.

As of June 2017, the Garmin G5 (all versions) do not have the ability to interface to an autopilot.
