PRIMARY EIS CAPABILITIES
With an installed interface module and sensors, GI 275 serves as an all-in-one primary EIS display for piston engine aircraft — so you can remove outdated analog gauges. Install dual GI 275 displays to monitor twin-engine aircraft.

COMPREHENSIVE INDICATIONS
The GI 275 main page displays engine, fuel and electrical data with easy-to-interpret color bands, bar gauge indications and numerical readouts. Your installer will configure your system for your aircraft with the appropriate indications.

PERCENT POWER
Calculated percent power can be displayed at the top of each EIS page. Using sensor readings, this provides an estimated percentage of the maximum engine power for the current engine power settings.

CHT/EGT MONITORING
Tap the temperature graphs on the main EIS page to enter the CHT/EGT page and view a detailed graphical display of cylinder head and exhaust gas temperatures, so you can pinpoint the optimal fuel/air mixture for efficient power management.

LEAN ASSIST MODE
GI 275 automatically checks the EGT of all cylinders and identifies your preferred rich/lean setting to balance efficiency and performance. The CHT/EGT page also displays markings above each cylinder to indicate peak temperatures during leaning operations.

NORMALIZED (NRM) MODE
In NRM mode, the CHT/EGT page displays engine temperatures relative to a normalized value to increase indication sensitivity, so you can see trends quickly.

PILOT ADVISORIES
Configure your GI 275 EIS to show alerts you’ve set to prevent getting close to POH limits, including high CHT, battery voltage, oil temperature, high CHT cooling rate and more.

EXCEEDANCES ALERTING
Color-coded pilot alerts/advisories, set up to POH limits, help maintain engine performance and safety. Flashing cues quickly identify out-of-limit exceedances.

AUTOMATIC DATA LOGGING
To help you maintain control over aircraft maintenance and operating costs, engine data is automatically logged by GI 275 EIS and easily downloaded for review.

DOWNLOAD WITH A GSB™ 15 CHARGING HUB
Pair with your GSB 15 USB charging hub to download engine data to a USB flash drive after your flight. Plus, charge USB-compatible portable electronic devices in flight with its dual ports.

STREAM TO GARMIN PILOT
With built-in Connext® wireless connectivity, GI 275 streams engine data to the Garmin Pilot app running on your compatible tablet or smartphone.

VIEW AT FLYGARMIN.COM
Upon landing, EIS data stored in the Garmin Pilot app is wirelessly uploaded to the flyGarmin website for viewing and secure storage. Or, you can upload it from your USB drive.

ANALYZE DATA
Your recorded data on your flyGarmin.com account can be retrieved and sent for third-party analysis to identify performance issues or maintenance needs in time to help avert more costly repairs later.

FUEL QUANTITY
See total fuel on board plus quantities for up to four tanks, including two main and two auxiliary tanks.

FUEL FLOW
Monitor fuel flow from the main page to track fuel efficiency and range — and view fuel pressure to verify optimal system operation.

INTEGRATED FUEL COMPUTER
GI 275 EIS monitors fuel flow and GPS information to estimate how much fuel, range and flight time you have left to go at current settings.

USER-SELECTABLE FIELDS
Customize the auxiliary page with up to four fields to display the additional EIS information relevant to your flight — including fuel used, UTC time, ground speed, range and more.

AIRCRAFT TIMERS
See your aircraft’s total Hobbs, Tach and flight time — as well as times for your current flight on the flight summary page.

FLIGHT SUMMARY DATA
View max RPM/temperatures as well as fuel and lean data updated dynamically throughout each flight on the flight summary page — then review after landing.
