Garmin® International Inc., a unit of Garmin Ltd. (NASDAQ: GRMN), announced an update for the GI 275 electronic flight instrument has been granted supplemental type certificate (STC) approval by the Federal Aviation Administration (FAA) and is available immediately through select authorized 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 (HSI) 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 (MFD) page.

GFC 500 autopilot compatibility with the GI 275

A single GI 2751 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 275’s, the secondary GI 2751 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 & 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.

Century II/III autopilot compatibility

The GI 275’s autopilot interface compatibility continues to grow with the addition of the Century II/III autopilots, which can now be paired with the GI 2752 to replace the antiquated attitude indicator3. When replacing the old attitude indicator, pilots receive a reliable electronic flight instrument with additional capabilities beyond the traditional display of attitude information. Furthermore, unlike legacy attitude indicators paired with the Century II/III autopilots, the GI 275 is capable of disconnecting the autopilot in the unlikely event of an attitude upset or in the event of a mis-compare of attitude data between two GI 275’s.

Additional GI 275 display enhancements

The GI 275 electronic flight instrument can display outside air temperature (OAT) and true airspeed (TAS) when using a temperature probe. OAT and TAS are displayed along the bottom of the display, while wind speed and direction are displayed above the heading and autopilot annunciations on the attitude indicator. Additionally, MFD data field enhancements allow pilots to easily edit and change data fields on the MFD page. Pricing for various configurations of the GI 275 can be found on the website.
