An update for Garmin's GI 275 electronic flight instrument has been granted STC approval by the FAA and is available immediately through select authorised Garmin dealers. The GI 275 can now be used with the GFC 500 autopilot to deliver superior in-flight performance and added redundancy when multiple GI 275 units are installed in an aircraft. In addition to GFC 500 compatibility, the GI 275 can serve as a replacement attitude indicator and/or horizontal situation indicator to legacy Century II/III autopilots. Additional features of the latest GI 275 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 page.

A single GI 275 electronic flight instrument can now be used as the attitude source to drive the GFC 500 autopilot, while also displaying mode annunciations and flight director indications. Its bright, high-resolution touchscreen display and wide viewing angle offer superior readability in the cockpit. For added redundancy in aircraft equipped with dual GI 275s, the secondary GI 275 is capable of coupling to the GFC 500 autopilot as well. In the unlikely event of a primary GI 275 failure, the autopilot remains fully functional when paired with the secondary GI 275. Additional redundancy is extended to include the G500 TXi and G600 TXi flight displays, which also allow the GI 275 to couple to the GFC 500 autopilot if needed when serving as a secondary instrument. Unique to the GI 275 and TXi, pilots will receive a mis-compare notification if the AHRS sources between the two do not align.

The GI 275's autopilot interface compatibility is also growing with the addition of the Century II/III autopilots, which can now be paired with the GI 275 to replace the antiquated attitude indicator. When replacing the old attitude indicator, pilots receive a reliable electronic flight instrument with additional capabilities beyond the traditional display of attitude information.
