Garmin GI 275 Attitude Indicator (AI/ADI) — Class I/II - 010-GI275-00
The Garmin GI 275 Attitude Indicator (AI/ADI) — Class I/II is an electronic flight instrument that provides solid-state attitude information in a compact, round-format display. It offers a practical path for replacing an aging vacuum pump-driven attitude indicator while retaining the classic instrument-panel appearance. Its configurable display can also consolidate essential flight data for a more capable primary flight reference.
Solid-State Attitude Reference
Reduce dependence on an aging vacuum-driven attitude system with ADAHRS-driven attitude information. The GI 275 can replace instruments such as the KI-256 while helping reduce weight and maintenance expense.
Essential Flight Readouts
Keep attitude, altitude, airspeed and heading together on the integrated display. This consolidation supports its use as a primary flight reference instrument.
Readable Touchscreen Display
View flight information on a bright, sunlight-readable 2.69” diameter touchscreen with 480 x 433 pixel resolution. A traditional concentric knob is also available for pilots who prefer knob-based data entry.
Navigation And Course Guidance
GI 275 can accept VOR/LOC and/or GPS course guidance inputs, along with distance and groundspeed indications. When available, it can show both lateral and vertical GPS/VOR/LOC course deviation cues for climb and descent profiles as well as approaches. Paired with select VHF Nav/Comms or GPS navigators, it can serve as a primary CDI for selecting, adjusting and tracking courses.
Configurable Awareness Tools
Optional Garmin SVT™ synthetic vision can overlay an attitude reference landscape and integrate a flight path marker. Selectable reference markers can identify arrival at a preselected altitude, heading or airspeed to aid overshoot avoidance. With the optionally available built-in autopilot interface, GI 275 can provide attitude information to drive select autopilots, including the GFC™ 500 autopilot, and display flight director command bar cues¹.
Expanded System Capability
For select aircraft and glass cockpit systems², GI 275 can operate as a standby flight instrument with MFD capability³ for mapping, traffic, weather and more. When paired with a GTN™ Xi series navigator, it enables Smart Glide™ functionality that can recommend an airport and create a Direct-to route during an engine failure. Dual ADAHRS GI 275 displays⁴ can provide reversionary backup capability, retaining attitude and heading data on the remaining HSI or MFD following an outage⁶.

REPLACE ANALOG GAUGES WITH ELECTRONIC DISPLAYS
Adaptable to a full range of instrument formats and functions, our GI 275 electronic display lets you keep the classic look of your panel while upgrading with modern, reliable glass touchscreen display technology.
BASIC ATTITUDE
Save weight and maintenance expense: replace that aging vacuum pump-driven attitude indicator — such as the KI-256 — with a reliable solid-state ADAHRS-driven GI 275 electronic display.
A LESS ARTIFICIAL HORIZON
To add situational awareness, your display can overlay attitude reference on an optional Garmin SVT™ synthetic vision landscape with flight path marker integration.
INSTRUMENT CONSOLIDATION
As your primary flight reference instrument, GI 275 features an integrated display to support all the essential readouts — attitude, altitude, airspeed and heading.
EDGE-TO-EDGE DISPLAY
The bright, high-resolution GI 275 touchscreen is sunlight-readable and maximizes the available space within the instrument panel cutout.
REFERENCE MARKERS
The GI 275 instrument can support display of selectable references to mark your arrival at a preselected altitude, heading or airspeed. Think overshoot avoidance.
ADI AUTOPILOT INTEGRATION
With optionally available built-in autopilot interface, GI 275 can provide precise attitude information to drive select autopilots (including the GFC™ 500 autopilot) and display flight director command bar cues1.
STANDBY ADI
For select aircraft and glass cockpit systems2, GI 275 can function as a standby flight instrument with MFD capability3 for mapping, traffic, weather and more. The GI 275D, a DAL-A certified variant, is also available for Part 25 applications with that requirement.
KNOB OR TOUCH CONTROLS
The touchscreen on GI 275 makes accessing its functions a breeze. A traditional concentric knob is also available for those who prefer that style of data input.
COMPATIBLE WITH SMART GLIDE™ TECHNOLOGY
When paired with the GTN™ Xi series navigator, GI 275 enables Smart Glide™ to give you a helping hand during an engine failure — including recommending an airport and creating a Direct-to route so you can land.
NAVIGATION GUIDANCE
In addition to primary magnetic heading reference, GI 275 can accept inputs for VOR/LOC and/or GPS course guidance — along with distance and groundspeed indications.
TRACK IN ALL DIMENSIONS
For climb/descent profiles and approaches, GI 275 can display both vertical and lateral GPS/VOR/LOC course deviation cues, when available.
ENHANCED HSI
With appropriate Nav inputs, GI 275 can optionally add HSI course guidance overlaid on a moving map display with flight plan legs, terrain, weather and more.
COMPLETE CDI SOLUTION
When paired with select VHF Nav/Comms or GPS navigators, GI 275 can serve as your primary indicator for making, adjusting and tracking course selections.
DUAL ADVANTAGES
With dual GI 275 displays4 as your primary flight instrumentation, reversionary backup capability retains attitude and heading data5 on the remaining HSI or MFD if an outage should occur6.
DIRECT-TO
For backup or nonprimary Nav reference, built-in VFR GPS capability5 enables convenient Direct-to guidance with position depicted on the moving map display.
MULTIFUNCTION DISPLAY
When configured as an MFD, GI 275 can serve multiple roles, supporting displays for moving map, traffic, lightning, weather, terrain, radar altimeter, CDI and more.
MOVING MAP
Within the MFD configuration, a dynamic moving map page offers views of terrain features, airports, airspace boundaries, navaids, flight plan routings and more.
TRAFFIC AND WEATHER
With select ADS-B “In” datalinks, GI 275 MFD pages will support subscription-free U.S. weather and traffic displays, including TargetTrend™ and TerminalTraffic™ technologies.
ANIMATED NEXRAD
When paired with an optional GDL® 69 SiriusXM® receiver, the MFD-configured GI 275 offers display capability for satellite weather coverage with graphical NEXRAD imagery.
RADAR ALTIMETER
For applications that require precise tracking of aircraft altitude above the terrain, GI 275 can provide display capability for select radar altimeters, including the Garmin GRA™ altimeter series.
WIRELESS DATA STREAMING
Use built-in wireless connectivity to share data between GI 275 and compatible mobile apps. Import databases. Stream weather, traffic, attitude information, EIS and more5.
TRANSPONDER CONTROL
In addition to ADS-B display capabilities, GI 275 can control GTX™ 345/GTX 345R series transponders. This allows pilots to control settings — such as squawk code, ident and flight ID — directly from the instrument’s touchscreen display.
ENGINE INFORMATION SYSTEM
With optional interface module and sensors, GI 275 can serve as a primary EIS display for piston engine, fuel, electrical and other data. Display space is optimized with bar graphs, bar gauge indications and numerical readouts. Use dual GI 275 displays to monitor twin-engine aircraft.
EGT/CHT MONITORING
Graphical display of cylinder head and exhaust gas temperatures allows you to pinpoint the optimal fuel/air mixture for efficient power management.
LEAN ASSIST MODE
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. Normalized mode is also available.
INTEGRATED FUEL COMPUTER
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.
EXCEEDANCES ALERTING
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.
FLIGHT SUMMARY DATA
See aircraft timers, max RPM/temperatures as well as fuel and lean data updated dynamically throughout each flight on the flight summary page — then review after landing.
USER-SELECTABLE FIELDS
Customize the auxiliary page with the additional EIS information relevant to your flight — including fuel used, UTC time, ground speed, range and more.
AUTOMATIC DATA LOGGING
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 flyGarmin.com® website. Once uploaded, your data can be shared automatically with select data analysis services for detailed insights about your flight.
