2.3.10.2 Location
Cockpit layout, size and operator’s preference will determine if only one set of lights is used (i.e., mounted in the
center), or if dual sets of lights are used (one set on each side), or a combination thereof is desired. For a typical
example of cockpit light locations refer to Figure 2-3. For panel cutouts and assembly options see the
manufacturer’s specifications. The following are recommended locations:
GPWS & BELOW G/S or PULLUP & GPWS
These lights should be located together and in the flight crew’s “primary field of view”. This would include either
the instrument panel or the edge of the glareshield.
GPWS FLAP OVRD -Optional-
This light should be located in the flight crew’s “field of view” and within reach of both crew members. This
light/switch may be located in an assembly with the GPWS and BELOW G/S lights and/or other EGPWS
annunciators.
GPWS CANCLD -Optional-
If used, this light should be located within at least one crew member’s “field of view”.
GPWS INOP
This light should be located within at least one crew member’s “field of view” or with other system INOP lights of
similar importance. It is recommended that this light not be located in the flight crew’s “primary field of view”. The
reason being that in the event of a GPWS system failure at the beginning of a flight, this light will remain “ON”
until the problem is fixed. This light may be combined with the TERR FAIL light.
TERR DISPLAY ON
This light should be located near the associated cockpit display, in the flight crew’s “field of view” and within
reach of one or both crew members. This light/switch may be located in an assembly with the TERR INHIBIT
light(s) and/or other EGPWS annunciators.
TERR INHIBIT ON
This light should be located in the flight crew’s “field of view” and within reach of both crew members. This
light/switch may be located in an assembly with the TERR DISPLAY light(s) and/or other EGPWS annunciators.
