GI 275 EIS With GEA 24

As an alternative to the dual-concentric knob, the intuitive touchscreen user interface now features page shortcuts that allow the pilot to switch pages with just a single touch of the display. Other enhancements include a new Flight Summary Page, Engine Percent Power display, EIS page shortcuts, user-customizable EIS fields, and more.

Aircraft Engine Monitor From Garmin Avionics

The GI 275 engine indication system (EIS) includes enhanced display layouts that optimize display space and show more engine data on a single page, ultimately helping pilots quickly view essential engine, fuel, and electrical data. In addition, improved graphical information and gauges are used to help pilots dynamically visualize sensor data and accurately assess the aircraft’s engine performance. 

Improved EIS page layouts and capabilities
A new bar graph on the Main EIS Page displays exhaust gas temperature (EGT) and cylinder head temperature (CHT) for individual cylinders. For quicker and easier interpretation of engine data, font sizes of select EIS values have been increased. In addition, a new combined EGT/CHT page brings these indications into a single page for simplified monitoring. Other new features include Normalized Mode and turbine inlet temperature (TIT) Lean functionality for appropriately equipped aircraft, improved fuel tank bar gauges, and the ability to display Engine Percent Power at the top of the screen.

New Flight Summary Page
A new Flight Summary Page contains aircraft timers, maximum RPM and temperature limitations for the engine, as well as fuel and lean data that is dynamically updated throughout the flight for real-time analysis in the air, along with a comprehensive post-flight review of engine data on the ground.

EIS Page shortcuts and customizable fields
Shortcuts have been added with increased touch functionality to enable pilots to quickly access more detail with regard to specific EIS data. With a single touch of the EGT/CHT indications on the main page, the GI 275 EIS quickly switches to the dedicated EGT/CHT page. To more easily access fuel calculations, pilots can touch the fuel gauge from the main page to switch to the fuel computer page. In addition, pilots can touch the RPM area on any page to return to the main page. Pilots also now have the ability to customize the AUX Page EIS fields relevant to their flight with user-selectable buttons accessed via the touch screen.

Wireless EIS Data Logging and Streaming
Pilots can stream and view EIS data in real-time on the Garmin Pilot App, with the data later uploaded automatically to for storage and further review. This seamless integration allows owners and operators to get the most out of their aircraft and engine investment by easily reviewing real-time and historical engine data performance at any time.

Lightweight and compact, the GI 275 EIS is a reliable, modern, and feature-packed engine indication solution intentionally designed to take advantage of the common 3.125-inch flight instrument size, reducing installation time and preserving the existing aircraft panel. In addition, its vibrant, high-resolution touchscreen display and wide viewing angle offer superior readability in the cockpit. These new GI 275 EIS capabilities are expected to be available in August 2021 via a software update. For full installation details, and to purchase the GI 275 EIS, contact a Garmin Authorized Dealer. The GI 275 also comes with a two-year warranty.

Engine Sensors Included with Packages:

4 or 6 Cylinder packages include the appropriate number of EGT/CHT senders/adapters, fuel flow sensor, and manifold pressure sensor when selected.



With optional interface module and sensors, GI 275 can serve as a primary EIS display for piston engine, fuel, electrical and other data. Use dual GI 275 displays to monitor twin-engine aircraft.


Graphical display of cylinder head and exhaust gas temperatures allows you to pinpoint the optimal fuel/air mixture for efficient power management.


This function of the Garmin EIS automatically checks the EGT of all cylinders and identifies your preferred rich/lean setting to balance efficiency and performance.


In addition to fuel quantity, the Garmin EIS monitors fuel flow and GPS information to estimate how much fuel, range and flight time you have left to go at current settings.


With EIS on your GI 275, color-coded pilot alerts/advisories help maintain engine performance and safety. Flashing cues quickly identify out-of-limit exceedances.


EIS data on the GI 275 electronic display is automatically logged and available for wireless Connext® streaming to your mobile device — with automatic cloud storage in the® website.
