Section XIII. LIGHTING
2.49 LIGHTING EQUIPMENT.
The lighting equipment consists of exterior and interior
lighting systems. The lighting equipment is controlled by
the pilot and CPG lighting control panels (fig 2-42).
Pilot and CPG Lighting Control Panels
The searchlight, crew station floodlights,
and utility lights are the only lights available
with battery power.
2.49.1 Exterior Lighting System.
The aircraft exterior
lighting system consists off formation lights, navigation
lights, anticollision lights, a searchlight, and an inspection
a. Formation Lights.
The formation lights (green)
are located on the upper surface of each wing, the upper
centerline of the aft fuselage, and on the upper surface of
the vertical stabilizer. Power for operation of the lights is
115 vac provided by the FORM circuit breaker on the pilot
overhead circuit breaker panel (fig 2-39). Operation of the
lights is controlled by the FORM rotary control on the pilot
EXT LT panel.
b. Navigation Lights.
The navigation lights are lo-
cated on the wingtips (right side green, left side red, and
the aft white) and on the top aft side of the vertical stabiliz-
er. Power for operation of the lights is 28 vdc and is pro-
vided by the NAV circuit breaker on the pilot overhead cir-
cuit breaker panel. Operation of the lights is controlled by
the NAV switch on the pilot EXT LT panel.
c. Anticollision Lights.
High-intensity flashing red
and white anticollision lights are located on each wingtip.
Power for their operation is 115 vac through the ANTI
COL circuit breaker and 28 vdc through the LT NAV circuit
breaker on the pilot overhead circuit breaker panel. Op-
eration of the lights is controlled by the ANTI-COL switch
on the pilot EXT LT panel.
The searchlight can reach temperatures
capable of igniting fires if contact is
made with combustible/flammable mate-
rials. Do not land in areas such as high
grassy meadows with the searchlight
Searchlight motion is inhibited for 60 sec-
onds after the SRCH LT switch is placed in
the STOW position.
The searchlight (fig 2-2) is located
in a fairing under the forward end of the forward avionics
bay just forward of the landing gear attachment and can
be used as a landing light. Power for the searchlight is 28
vdc routed through a relay by the SRCH LDG CONTR and
SRCH LDG circuit breakers on the pilot overhead circuit
breaker panel. Operation of the light is controlled by the
SRCH LT and EXT-RET switches on the pilot and CPG
collective stick switchboxes (fig 2-26).
