Garmin Introduces GI 275 Electronic Flight Instrument
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)1. 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 autopilot sand 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.
Suitable as a replacement to many aging flight instruments and gyro-based attitude indicators on the market — such as the popular KI-256 — GI 275 gives aircraft owners the benefits of a modern and reliable flight instrument. GI 275 boasts a standard 3.125-inch form factor and rear-mount design that minimizes panel modification. Its bright, high resolution touchscreen display and wide viewing angle offer superior readability in the cockpit.
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.
Several variants of GI 275 are available to meet the needs of more than 1,000 business and general aviation aircraft models. The GI 275 Base variant can be utilized as a dedicated EIS or CDI/MFD with features such as traffic, weather, terrain, SafeTaxi® airport diagrams, and more. The GI 275 ADAHRS variant includes a built-in ADAHRS and backup battery,making it capable for use as a dedicated 3-in-1 flight instrument with attitude, airspeed and altitude. When connected with an optional magnetometer, this variant can serve as a dedicated HSI or 4-in-1 flight instrument with attitude, airspeed, altitude and heading information. The GI 275 ADAHRS+AP variant is also available, which carries the capabilities of the ADAHRS variant and adds the ability to interface with many popular legacy autopilots.
Primary Attitude Indicator
When installed as a primary attitude indicator, GI 275 offers improved reliability, potential weight savings and reduced maintenance compared tofailure-prone vacuum-driven attitude indicators. In addition to serving as primary for attitude information, pilots can also view primary altitude,airspeed and heading information on the instrument. Optional SVT™overlays a rich, 3D topographic view of terrain, traffic, obstacles, airport signposts and more all within the GI 275 attitude display. With SVT, the GI 275also displays a flight path marker, which considers crosswind, angle of attack and other factors to show precisely where the aircraft is flying. GI 275 is compatible with the GFC™ 600 autopilot — as well as an array of third-party autopilots — and can replace the primary attitude indicator installed with these autopilots. GFC 500 compatibility is expected later this year.
GI 275 flight instrument is also approved for installation as a dedicated standby flight instrument to Garmin glass flight displays and is capable of serving as a back-up to a variety of third-party flight displays on the market. When installed as a standby to G500 TXi, GI 275 is capable of displaying additional multifunction display features. For back-up navigation information, a built-in VFR GPS enables convenient direct-to navigation guidance, displaying aircraft position information on a moving map.
Course Deviation Indicator (CDI) & Horizontal Situation Indicator (HSI)
When installed as a CDI or HSI, the GI 275 flight instrument 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 navigation sources 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 glideslope deviation can be viewed on the GI 275. CDIsource selection can be accomplished through the touchscreen interface, while course and heading selection is completed by using either the touchscreen or dual concentric knob. When pilots replace an older mechanical CDI or HSI,GI 275 doubles as a modern digital indicator and adds MFD-like capabilities such as a moving map, weather, traffic and terrain.
Suitable as a replacement to display primary engine information
When configured as primary to display engine information, GI 275 is capable of interfacing with single-engine and multi-engine normally aspirated or turbocharged aircraft with select powerplants, including Lycoming and Continental 4 or 6-cylinder engines. When GI 275 replaces mechanical gauges and is configured as primary for engine information, GI 275 can display RPM, manifold pressure, oil pressure and temperature, cylinder head temperature (CHT), exhaust gas temperature (EGT), turbine inlet temperature (TIT), fuel flow, fuel quantity, fuel pressure, volts and amps.Lean assist functionality is also available, so pilots can choose to operate richof peak or lean of peak. GI 275 also features exceedance alerting, allowing installers to configure caution and warning alerts per the Pilot’s Operating Handbook (POH). Advisory alerts such as “high oil temp” or “high CHT” can be configured by the pilot. These exceedances, as well as additional engine data can be shared wirelessly with the Garmin Pilot™ app on Apple® mobile devices and can also be viewed onthe fly Garmin® website for post-flight analysis. In multi-engine aircraft, dual GI 275 flight instruments are required to display engine information. To gather engine data, the GI 275 uses either the GEA™ 24 or GEA 110 engine interface adapters as well as the same engine sensors as TXi flight displays.
Depending on the configuration and installation, GI 275 is capable of displaying additional page functions and features beyond a traditional flight instrument. These features can include the following:
- A multifunction display (MFD) with a moving map can display terrain,obstacles, traffic, weather, airspace information, airways, and more.
- When interfaced to a GTX™ 345 or GNX™ 375, traffic information can be displayed on the dedicated traffic page or moving map.Patented TargetTrend™ relative motion technology and pop-up traffic alerts further enhance situational awareness.
- GI 275 can also be interfaced to a variety of traffic systems, including select Traffic Advisory (TAS) and Traffic Alert and Collision Avoidance Systems (TCAS). Traffic advisories are displayed on the dedicated traffic page and moving map.
- SafeTaxi airport diagrams display runways, taxiways, Fixed Based Operators (FBO’s), hangars and more relative to the aircraft’s location on the airport surface.
- Terrain shading incorporates yellow and red contouring indicating that the aircraft is 1,000 and 100 feet above ground level (AGL) respectively. Terrain information — as well as obstacle and WireAware™database information — can be viewed on the terrain and map pages.
- GI 275 uses its internal terrain and obstacle database to provide audible and visual terrain proximity alerts,including, “terrain ahead, pull up” and “obstacle ahead, pull up.”
- When paired with the GDL® 69 datalink receiver, GI 275 is capable of displaying SiriusXM® Aviation Weather. It can also display Flight Information Service-Broadcast (FIS-B) weather from either a GTX™ 345 or GNX 375.
- An airport information page displays a variety of information,including frequencies, runway dimensions and more.
- GI 275 can be paired with the GRATM 55 or GRA 5500 radar altimeters — as well as other third-party products — to display radar altimeter readings on a dedicated page. Visual and aural annunciations are also available.
Built-in Wi-Fi® connectivity enables Database Concierge, the wireless transfer of aviation databases to the GI 275. Pilots also have the option of transferring databases to GI 275 by using a USB flash drive and the GSB™ 15 USB charger. Databases can also be synced among multiple GI 275 flight instruments in a single cockpit. When configured to display engine information, GI 275 can wirelessly send engine data to display within the Garmin Pilot™ app on Apple® mobile devices. This data is also automatically synced and can also be viewed on the flyGarmin® website.Wireless flight plan transfer via BLUETOOTH® technology is available when GI 275 is paired with a GPS 175, GNC® 355 or GNX™ 375.
