Engine Monitoring: When equipped with optional adapters and probes, the GI-275 can serve as an engine information system (EIS) for piston aircraft.
ADAHRS and Autopilot-Integrated Models
The GI-275 models with Air Data Attitude & Heading Reference System (ADAHRS) provide advanced flight instrument capabilities:
GI-275 ADAHRS Model: Displays attitude, altitude, airspeed, and heading. When paired with a magnetometer, it can function as a Horizontal Situation Indicator (HSI).
GI-275 ADAHRS + Autopilot (AP): The most advanced version, this model provides heading, course error, and gyro outputs to compatible autopilot systems.
The GI-275 also functions as a certified TCAS I/II traffic alert indicator and an Electronic Standby Instrument (ESI) replacement for turbine-powered and business jet aircraft. Garmin offers a wide-ranging Approved Model List (AML) for Supplemental Type Certificates (STCs), available through Garmin and third-party providers like Southeast Aerospace.

Why do some parts indicate "REQUEST" or “RFQ” on the Southeast Aerospace website?
In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.
In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
Is the backup battery required for all Garmin GI-275 indicators?
The backup battery offered with the GI-275 is optional for the GI-275 base configuration and standard for the GI-275 ADAHRS, ADAHRS+AP configurations.
Why is GPS a required input for attitude with the GI-275
The GI-275 requires GPS for attitude aiding. The GI-275 contains an internal VFR GPS receiver that can be connected to a GPS antenna mounted on the glareshield or it can receive input from an external GPS. As per the STC, the GI-275 can receive GPS data for aiding by the following methods/models:
Glareshield GPS antenna
GTN-6XX/7XX
GNS-4XX/5XX
GNS-480
GTX 3X5 Transponder w/ internal GPS
GPS-175/GNX-375/GNC-355
What version of the Garmin GI-275 is required for Primary ADI?
In order for the GI-275 to be the approved primary attitude indicator for an aircraft on the STC Approved Model List, the ADAHRS version of the GI-275 must be purchased.
How can I safely clean and disinfect my Garmin avionics?
Garmin has provided Service Advisory 2051 for general recommendations, materials, and supplies to clean and disinfect Garmin products. Otherwise, not following the recommendations could void the warranty.
Cleaners containing ammonia will harm the anti-reflective coating on many Garmin aviation display lenses.
Disinfectant with a solution of 70% isopropyl alcohol that does not contain ammonia is preferred. Solutions of up to 91% isopropyl alcohol are also acceptable.
Clean the display lens using a clean lint-free cloth and a cleaner that is specified as safe for anti-reflective coatings.
For other exposed surfaces such as knobs, buttons, and bezels, a damp cloth with soap and water is acceptable.
Bleach-based cleaners, ammonia-based cleaners, or other harsh chemicals on any surface are not recommended.
Remove all soap/soap residue to prevent buttons and knobs from gumming up or becoming slippery.
Many aviation products are not rated as waterproof. Spraying or wetting the units to the extent where moisture could go beyond the exterior surfaces could damage the unit.
Garmin announced pricing and availability of the GI 275D standby flight display. The GI 275D is designed to be dissimilar from other Garmin primary flight display (PFD) systems and ADAHRS systems for
applications with such requirements. Approved with Designed Assurance Level (DAL) A, the GI 275D is ideal for retrofit installations in Part 25 aircraft.
The GI 275D can display either internal or external AHRS and ADC sources but has no sensor reversion capabilities.
The GI 275D is a dedicated ADI that can be configured for both 3 in 1 or 4 in 1 operations. Additionally, the GI 275D can act as a dissimilar standby flight display for certain applications.
The GI 275D is TSO approved but Garmin does not have an AML STC. An initial STC for the installation of the GI 275D is available from Southeast Aerospace.
