An update for Garmin’s GI 275 electronic flight instrument has been granted supplemental type certificate (STC) approval by the FAA.
The update allows the GI 275 to be used with the GFC 500 autopilot to deliver in-flight performance and added redundancy when multiple GI 275 units are installed in an aircraft.

The GI 275 also can serve as a replacement attitude indicator and/or horizontal situation indicator (HSI) to legacy Century II/III autopilots.
Additional features of the latest upgrade include the display of outside air temperature, groundspeed, true airspeed and wind on the attitude indicator, as well as data field enhancements on the multi-function display (MFD) page, according to company officials.
