GI 275 Simplifies Avionics Upgrades in Part 27 Helos
Garmin's new GI 275 electronic flight instruments feature touchscreen and dual concentric knob control.

Garmin’s GI 275 electronic flight instruments are a simple way to replace older analog flight instruments, mounting from the rear of the instrument panel in standard 3.125-inch instrument holes. GI 275 units are controlled via touchscreen and dual concentric knobs. 

For Part 27 helicopters, GI 275 installations include the GI 275 as a course-deviation indicator (CDI), radar altimeter display, and multifunction display (MFD). According to Garmin, “The GI 275 has completed stringent helicopter vibration and temperature testing, demonstrating it can withstand the harsh operating environments encountered by helicopters.” Further approvals under FAA supplemental type certificates will allow the GI 275 to replace attitude and horizontal situation indicators. Availability of the GI 275 for rotorcraft is expected in the second quarter of this year.
