MK XXII EGPWS Installation Manual

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.
