Garmin GI 275 for Part 23 and Part 25 applications

Garmin continues to impress with creative and functional products. The focus of this article, the GI 275, is no different.    In addition to filling a broad range of functions for single engine and multi-engine Part 23 aircraft, the GI 275 is delivering benefits into the Part 25 market in a very useful way. 

The GI 275 is a 3 ¼” multi-function electronic display.  The LED display is bright and sunlight readable.   In certain Part 23 aircraft, this unit can function as a Horizontal Situation Indicator (HSI), Attitude Display Indicator (ADI), Multi-function Display (MFD), or Engine Instrument System Indicator (EIS).  This will depend on certification, how the unit is configured and interfaced for the intended purpose.  The GI 275 comes with optional sensors and an internal battery depending on the function you require.   

Garmin’s AML STC would cover most Part 23 models to include King Air models, Conquest and the Citation CJ models. 

In the Part 25 market, a number of useful STCs have been developed to help with some obsolescence issues.   The first two available STCs would allow the GI-275 to function as a replacement Standby Attitude Indicator.   Many of the older analog standby attitude indicators and multi-function CRT displays utilized for standby attitude (for example, the Secondary Nav. Display found in Citation and Hawker models) are facing obsolescence.  Hard to find, expensive to replace.   The GI-275 would be a new, cost- effective way to solve this problem.

Models that can benefit:   Challenger 600 series, Falcon models, Gulfstream models, Learjet models, Hawker models, Citation models,

A separate STC was developed by Dassault which also covers a Standby Attitude Indicator replacement in the Falcon models with EASy cockpits such as the 7X, 8X, 900EZ/LX/DX, 2000EZ, LX, DX. 

Another area of obsolescence which the GI 275 can be helpful is serving as an Instant Vertical Speed Indicator (IVSI).  If the airplane has Honeywell IVA-81 IVSI displays included in the Honeywell TCAS II systems, the GI-275 may be a replacement option.    The IVA-81 is becoming hard to replace and repair.    Models would include Falcon 10, 50, Astra, Challenger 604 variants, Learjet models, Hawker models, Citation 550, 560, 650 and others.
