Overview REPLACE ANALOG GAUGES WITH ELECTRONIC DISPLAYS
Adaptable to a range of instrument formats and functions, our GI 275 electronic displays let you retrofit your Part 27 helicopter with modern, reliable touchscreen display technology.
Out with the old, in with the new. It flush mounts in a standard 3-1/8″ round cutout.
It’s STC’d for select Part 27 helicopters.
How do you see it? Attitude, altitude, airspeed, CDI, HSI or MFD?
It comes with built-in VFR GPS – and it’s available with precise digital ADAHRS.
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.
Fly with an attitude that inspires trust.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 HSVT synthetic vision landscape with WireAware wire-strike avoidance technology.
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 alerts to mark your arrival at a preselected altitude, heading or airspeed.
STANDBY ADI GI 275 can function as a standalone standby flight instrument to back up existing attitude indicators or flight displays.
KNOB OR TOUCH CONTROLSThe 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.
Gain solid direction for primary navigation.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, obstacles wires, 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 displays as your primary flight instrumentation, reversionary backup capability retains attitude and heading data on the remaining HSI or MFD if an outage should occur1.
DIRECT-TO Built-in VFR GPS navigation enables convenient Direct-to guidance with position depicted on the moving map display.
See more information as you fly your mission.MULTIFUNCTION DISPLAY When configured as an MFD, GI 275 can serve multiple roles, supporting displays for moving map, traffic, terrain, wires and obstacles, weather, CDI and more.
MOVING MAP Within the MFD configuration, a dynamic moving map page offers views of terrain, obstacles, wires, 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 NEXRADWhen 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 be configured as a dedicated display for select radar altimeters, including our GRA altimeter series (sold separately).
HTAWS SUPPORTIn addition to basic forward-looking terrain avoidance technology, GI 275 supports optional HTAWS capabilities when paired with a GTN series, GTN Xi series or WAAS-enabled GNS series navigator2.
OUTSIDE AIR TEMPERATUREPair GI 275 with an optional GTP 59 OAT probe to see true airspeed, density altitude and other essential flight calculations.
WIRELESS DATA STREAMINGUse built-in wireless connectivity to share data between GI 275 and compatible mobile apps. Import databases. Stream weather, traffic, attitude information and more3.
