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 2-7. For panel cutouts and assembly options
see the manufacturer’s specifications in Appendix D. The following are recommended locations:
GPWS warning (red) & GPWS alert (amber)
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.
LOW ALTITUDE
This light should be located in the flight crew’s “field of view” and within reach of both crewmembers. This
light/switch may be located in an assembly with the GPWS red and GPWS amber lights and/or other
EGPWS annunciators.
TERR INHIBIT ON (Optional see section 2.3.10.3)
This light should be located in the flight crew’s “field of view” and within reach of both crewmembers. This
light/switch may be located in an assembly with the TERR DISPLAY light(s) and/or other EGPWS
annunciators.
AUDIO INHIBIT ON (Optional see section 2.3.10.3)
This light should be located in the flight crew’s “field of view” and within reach of both crewmembers. This
light/switch may be located in an assembly with the TERR DISPLAY light(s) and/or other EGPWS
annunciators.
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 crewmembers. This light/switch may be located in an assembly with the TERR
INHIBIT light(s) and/or other EGPWS annunciators.
GPWS INOP
This light should be located within crewmember’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.
TERR INOP
This light should be located within at least one crewmember’s “field of view” or with other system INOP
lights of similar importance. Note: Annunciators are available with split legend GPWS INOP / TERR INOP
in one assembly. 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.
