GI 275 Available for Helicopter Installations

Garmin is pleased to announce that the GI 275 electronic flight instrument is now able to be installed into Helicopters. The GI 275 has completed stringent helicopter vibration and temperature testing, demonstrating it can withstand the harsh operating environments encountered in helicopters.

Initial variants include the course deviation indicator (CDI), radar altimeter display, and the multi-function display (MFD) versions of the GI 275. Follow-on approval of the GI275 as a replacement for the attitude indicator (AI) and horizontal situation indicator (HSI) is expected via a FAA STC in the fourth quarter of 2020. Once completed, Garmin will seek EASA validation. Installation of the MFD version can potentially be undertaken via a FAA Field approval, or EASA minor change process.

Part Changes

A new adapter plate kit for helicopter installations has been created. For rotary applications that also need an adapter plate, the 011-05285-01 kit is required. The new kit is qualified for both fixed wing and helicopter installation, but the original kit (011-05285-00) is not to be used in helicopter installations. The 011- 05285-00 kit will continue to be sold for a limited time, transitioning to 011-05285- 01 as the only option for both fixed wing and helicopter installations in the future. The new kit will be added to the latest Aviation Dealer Price Catalog , which will be available to download from the DRC.
