System Overview - Garmin GI 275 Installation Manual

1.2 System Overview

The GI 275 is a multi-function electronic instrument display capable of operating as a standalone display.
It features a bright, sunlight readable, 3⅛-inch diameter color display that is sized to fit in a standard
instrument cutout.
The GI 275 Multi-Function Instrument can be configured as the following indicator types:
•
Multi-Function Display Indicator (MFD) functions shown in Section 1.2.2.1
•
Engine Instrument System Indicator (EIS) functions shown in Section 1.2.2.2
The following dedicated pages are available on a GI 275 MFD:
• CDI (MFD only)
• HSI
• Stormscope
• Terrain
• Moving Map
• Radar Altimeter
• Traffic
• Weather
• Transponder
The GI 275 EIS uses the GEA 24 and sensors to replace various engine instruments and provide indication
of engine parameters. For a single engine, a single GI 275 with multiple pages can be used; however, all
primary alerting gauges must fit on the primary gauge page.
For twin-engine EIS, each engine must have a dedicated GEA 24 and each engine must have separate
GI 275 indicators. Only one indicator is permitted per engine. If multiple indicators are needed to display
all primary alerting gauges, then certain existing gauges must be retained instead.
EIS units may not share a GEA 24 interface with a G3X system. If using a GI 275 for EIS, then the EIS
interface may only be connected and displayed on the GI 275 system, and may not be connected or
displayed on a G3X system.
