DESCRIPTION

Garmin GI 275 3-1/8” Glass Flight Instrument, Horizontal Situation Indicator (HSI)
Includes Backup Battery Unit for Up to 60 Minutes of Flight Time

REPLACE ANALOG GAUGES WITH ELECTRONIC DISPLAYS

Adaptable to a full range of instrument formats and functions, the GI 275 electronic display lets you keep the classic look of your panel while upgrading with modern, reliable glass touchscreen display technology.

Out with the old, in with the new. It flush mounts in a standard 3-1/8” round cutout.
From piston singles to jets, it’s STC’d for more than one thousand make/model aircraft.
How do you see it? Attitude, altitude, airspeed, CDI, HSI, MFD or EIS.
It’s available with precise digital ADAHRS and interface to drive select autopilots.
Connect your cockpit with built-in Wi-Fi® connectivity and BLUETOOTH® technology.
Know you’ll get home with up to 60 minutes of optional backup battery power.

A dual concentric knob allows pilots to access a variety of key functions within the flight instrument, such as adjustments to the baro setting or airspeed bug. Highly scalable, aircraft owners can start with a single GI 275 and add up to a total of six in a single panel, paving the way for incremental upgrades and an array of individualized panel configurations.

Course Deviation Indicator (CDI) & Horizontal Situation Indicator (HSI)

When installed as a CDI or HSI, the GI 275 is designed to accept a variety of GPS or navigation inputs, allowing up to two GPS sources and two VHF navigation sources. The GI 275 features an Omni Bearing Resolver that allows the flight instrument to interface to a variety of legacy navigators on the market without the need for an expensive adapter. With an optional magnetometer, it is also capable of providing magnetic-based HSI guidance. Vertical and lateral GPS, VOR/LOC and glide slope deviation can be viewed on the GI 275. CDI source selection can be accomplished through the touchscreen interface, while course and heading selection is completed using either the touchscreen or dual concentric knob. When pilots replace an older mechanical CDI or HSI, the GI 275 doubles as a modern digital indicator and adds MFD-like capabilities such as a moving map, weather, traffic and terrain.

Garmin is pleased to introduce GI 275, a powerful electronic flight instrument that directly replaces legacy primary flight instruments in the cockpit. GI 275 is suitable as a direct replacement for a variety of instruments, including an attitude indicator, attitude directional indicator (ADI), course deviation indicator (CDI), horizontal situation indicator (HSI), multi-function display (MFD) and engine indication system (EIS). Capable of serving as a 4-in-1 flight instrument with attitude, airspeed, altitude and heading information, GI 275 can also be installed as a standby to a number of glass flight displays and is available with a 60-minute back-up battery. Lightweight and compact, the GI 275 is intentionally designed to take advantage of the common 3.125-inch flight instrument size, reducing installation time and preserving the existing aircraft panel. It’s also compatible with a variety of third-party autopilots and does not require a separate interface adapter, further reducing installation labor. GI 275 has received Federal Aviation Administration (FAA) approval and is available immediately for installation in more than 1,000 single-engine and multi-engine aircraft models.

BASIC ATTITUDE

Save weight and maintenance expense: replace that aging vacuum pump-driven attitude indicator 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 and display flight director command bar cues.

STANDBY ADI

For select aircraft and glass cockpit systems¹, GI 275 can function as a standby flight instrument with MFD capability2 for mapping, traffic, weather and more.

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.

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 radios or GPS navigators, GI 275 can serve as your primary indicator for making, adjusting and tracking course selections.

DUAL ADVANTAGES

With dual GI 275 displays³ as your primary flight instrumentation, reversionary backup capability retains attitude and heading data4 on the remaining HSI or MFD if an outage should occur.

DIRECT-TO

For backup or nonprimary nav reference, built-in VFR GPS capability⁴ 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 the GI 275 and compatible mobile apps. Import databases. Stream weather, traffic, attitude information, EIS and more⁴.

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. 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.

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.

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.

² Standby ADI with HSI or MFD pages is available only for Class I/II aircraft
³ Both GI 275 units must be ADAHRS versions to support reversionary capability
