GI 275: Aircraft Flight Instrumentation Reimagined


January 15, 2020

Introducing GI 275, a powerful electronic flight instrument that directly replaces legacy primary flight instruments in the cockpit. The 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) and engine indication system (EIS). Capable of serving as a 4-in-1 flight instrument, the 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, it 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. The GI 275 has received FAA approval and is available immediately for installation in over 1,000 single-engine and multi-engine aircraft models.

Several variants of the GI 275 are available to meet the needs of over one thousand business and general aviation aircraft models. Features beyond the traditional display of attitude, airspeed and altitude include the option to display CDI, HSI, and engine information. The GI 275 is also capable of displaying multifunction display-like features, such as traffic, weather, terrain, SafeTaxi airport diagrams, optional Synthetic Vision Technology (SVT) and more.

“As constant innovators within the avionics industry, we’re redefining
the aircraft cockpit with the introduction of the GI 275,” said Carl Wolf, vice
president of aviation sales and marketing. “With the GI 275, pilots can
take an economical and scalable approach to their avionics upgrade, while
saving on the installation labor and cost. If it’s round and in their panel,
pilots can likely replace it with the GI 275 to receive modern flight display
features and benefits in a powerful, yet compact touchscreen flight
instrument.”

Suitable as a replacement to many aging flight instruments and
gyro-based attitude indicators on the market such as the popular KI-256, the GI
275 gives aircraft owners the benefits of a modern and reliable flight
instrument. The 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 offers 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 the 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.

When installed as a primary attitude indicator, the GI 275 offers improved reliability, potential weight savings and reduced maintenance compared to failure-prone vacuum-driven attitude indicators. When the GI 275 serves as primary for attitude information, pilots can also view altitude, airspeed and headingon the instrument. Optional SVT overlays a rich, 3D topographic view of terrain, traffic, obstacles, airport sign posts and more all within the GI 275 attitude display. The GI 275 also overlays a flight path marker within the SVT view, which takes into account crosswind, angle of attack and other factors to show precisely where the aircraft is flying.

The 4-in-1 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 the G500 TXi, the 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. In
installations where the GI 275 is installed as a primary or standby flight
instrument, a 60-minute back-up battery is included.      

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…
