Garmin announces an update to the certification of the GI 275 electronic flight instrument for select Part 27 helicopters
Garmin announced that the Federal Aviation Administration (FAA) has granted Supplemental Type Certification (STC) for the GI 275 electronic flight instrument, set for completion in March 2022. This instrument is designed for Part 27 VFR helicopters, starting with the Bell 206. Designed to replace legacy flight instruments, the GI 275 offers a cost-effective upgrade with modern features, including a high-resolution touchscreen and optional synthetic vision technology. Expected additional certifications for other helicopter models in the second half of 2022 will enhance Garmin's presence in the aviation market.

STC to include Bell 206 with additional models expected in the second half of 2022
“We are thrilled to bring the popular and extraordinarily capable GI 275 to the helicopter market,” said
The GI 275 is intentionally designed to take advantage of the common 3.125-inch flight instrument size, reducing installation time and preserving the existing instrument panel. Its bright, high-resolution touchscreen display and wide viewing angle offer superior readability in the cockpit. In addition to interfacing with the flight instrument via the touchscreen, a dual concentric knob allows pilots to access a variety of key functions. Suitable as a direct replacement to many aging flight instruments, the GI 275 offers operators a simple and straightforward upgrade path to achieve modern flight instrument features and functions.
Primary attitude indicator
When installed as a primary attitude indicator, the GI 275 offers improved reliability, potential weight savings and reduced maintenance compared to less reliable, vacuum-driven attitude indicators. Optional Helicopter Synthetic Vision Technology (HSVT™) overlays a rich, 3D topographic view of terrain, traffic, obstacles, power lines, airport signposts and more, all within the GI 275 attitude display.1 Additional features include the display of outside air temperature, groundspeed, as well as true airspeed and wind information on the attitude indicator, and wireless functionality like sharing of GPS position and backup attitude information to the Garmin Pilot™ mobile application.
Course deviation indicator (CDI) & horizontal situation indicator (HSI)
When installed as a CDI or HSI, the GI 275 is designed to accept a variety of GPS and navigation inputs, allowing up to two GPS sources and two VHF navigation sources. The GI 275 features an Omni Bearing Resolver that allows the flight instrument to interface to a variety of legacy navigators on the market without the need for an expensive adapter. With an optional magnetometer, it is also capable of providing magnetic-based HSI guidance. The HSI can also provide enhanced features such as map inset and traffic, terrain or weather overlay. Selecting the CDI source is simple and can be accomplished through the touchscreen interface, while course and heading selection is completed using either the touchscreen or dual concentric knob.
Multi-function display (MFD)
When helicopter owners replace an older mechanical CDI or HSI, the GI 275 doubles as a modern digital indicator and adds MFD-like capabilities such as a moving map, weather, traffic, obstacles, WireAware™ power lines, SafeTaxi® airport diagrams and five-color terrain shading. For backup navigation information, a built-in VFR GPS enables convenient direct-to navigation guidance, displaying aircraft position information on a moving map. HTAWS (Helicopter Terrain Awareness and Warning System) is available on the GI 2752 and offers forward-looking terrain and obstacle avoidance (FLTA) capability to alert in advance where potential hazards may exist. The GI 275 can also be paired with Garmin’s GRA® 55 or GRA 5500 radar altimeters, or other select third-party products, to display altitude Above Ground Level (AGL) while also providing visual and aural annunciations to the pilot.
The GI 275 will soon be available for installation in select Part 27
