The Garmin GI 275 ADAHRS (Part Number 010-02326-10) adds advanced electronic flight information capabilities to virtually any aircraft panel. Whether used as a primary flight instrument or as a backup display, the GI 275 brings modern technology and a sophisticated appearance while presenting critical flight information in a clear, intuitive format.
While maintaining the familiar look of traditional round instruments, the GI 275 provides a brighter, more precise display that is easier to read and operate. It can also eliminate the need for aging vacuum-driven instruments, helping improve reliability while reducing maintenance associated with mechanical gyros and vacuum systems.
Designed to fit a standard 3-1/8-inch instrument opening, the GI 275 offers a straightforward upgrade path for replacing traditional attitude indicators and other legacy flight

instruments. Its compact design allows many aircraft owners to modernize their panels without extensive panel modifications.
A single GI 275 can function as a primary attitude indicator while displaying critical flight information including attitude, altitude, airspeed, and heading on a bright, sunlight-readable display. The system also offers a variety of advanced optional features and can be configured for multiple applications. When paired with additional GI 275 units, it can provide expanded flight instrumentation, enhanced situational awareness, and engine monitoring capabilities, creating a highly capable and customizable glass-panel solution.
