GENERAL
The GI 275 Multifunction Instrument (hereafter referred to as the “GI 275”) is a
panel-mounted, multifunction instrument with a single touch display and virtual
“Pages” within each instrument that may be configured as individual
“instruments”. The GI 275 can be configured as an ADI, HSI, EIS or MFD with
multiple hazard awareness pages, depending on the number and type of
integrated navigation and hazard sensor sources. The GI 275 can be used as a
primary Engine Indication System (EIS) for single and twin-engine aircraft. The
ADI and HSI can be installed as stand-alone primary flight instruments as long
as there are other equivalent source(s) of primary flight information that are
independently powered. The ADI or HSI can also be installed as a backup
instrument. Any GI 275 ADI, HSI, or MFD may be configured with an optional
internal battery to provide an independent and automatic backup power source.
Individual GI 275s may be grouped or connected as follows to expand and
enhance their capabilities and to provide redundancy. Groups of connected GI
275s are hereafter referred to as a “GI 275 system” in this document.
Attitude Direction Indicator (ADI) Units configured as an ADI will
contain a single page that displays
aircraft attitude.
Altitude, airspeed, vertical speed
and heading may also be displayed
on the ADI page depending on the
aircraft configuration.
