NOTE
If the GI 275 EIS is installed outside the pilot's field-of-view, and a PFD capable of annunciating
EIS warnings and cautions is not installed, a remote annunciator(s) will be required as an engine
caution and warning advisory. The annunciator(s) must be located within the pilot's primary field-
of-view. Refer to Section 4.4.3.
4.4.1

GI 275 Multifunction Indicator

CAUTION
It must be verified that the original airspeed indicator is not part of an existing airspeed warning
system when considering instrument removal or replacement. If it is part of the airspeed warning
system, this system must continue to operate following the installation of the GI 275 system.
NOTE
If applicable for the installation, ensure the backup battery is installed prior to installation of the
GI 275 unit in the instrument panel. The backup battery is required if the GI 275 is installed as a
primary or standby attitude display. Refer to Section 4.4.2 for battery installation procedure.
When replacing existing "six pack" 3-inch diameter flight instruments, GI 275 displays can be positioned
at any location vacated by the existing instruments except for the GI 275 Primary ADI. The GI 275
Primary ADI must be installed at the top-center of the "six pack" arrangement. For aircraft instrument
panels that do not have a "six pack" type arrangement, the general rule is that the GI 275 ADI should
coincide with the pilot's point-of-view centerline. The other GI 275 display(s) must be within the pilot's
field-of-view. AC 23.1311-1C requires that the primary flight information instruments be installed within
the primary field-of-view. GI 275 EIS units in twin-engine aircraft must be located adjacent to each other
and oriented (i.e., vertically or horizontally) the same as the previously approved installation.
If required by the installation (refer to Section 3.2.2), the display backup toggle switch that allows for the
control of reversion between the primary and standby displays must be located in the vicinity of the
reverting display.
