INTERIOR LIGHTING
COCKPIT LIGHTING
General
Controls for lighting are either on the device
or as illustrated in Figure 3-1.
Instrument Panel Post and
Eyebrow Lights
The pilot’s and copilot’s instrument panel post
lights and eyebrow lights are individually con-
trolled by separate rheostat switches that have
an off detent. The pilot’s switch is located on
the cockpit left side immediately aft of the
pilot’s subpanel. The copilot’s switch is located
on the cockpit right side. A third switch, on the
cockpit left side, controls the center instrument
panel lights. The lights are powered by light
d i m m e r a s s e m b l i e s t h r o u g h t h e r h e o s t a t
switches. The light dimmer assemblies are lo-
cated in the nose compartment.
Instrument Panel Floodlights
The pilot’s and copilot’s floodlights, located
under the glareshield, are individually con-
trolled by separate on–off rheostat switches.
The pilot’s controls on the left side, and the
copilot’s, on the right side of the cockpit,
control separate sections of the floodlights.
The lights are powered through the INSTR
LT circuit breakers.
Map Reading Lights
The map reading lights, located on the left
side of the pilot and right side of the copilot,
are controlled by rheostat switches adjacent
to the lights (Figure 3-2). The lights are pow-
ered through the LH and RH INSTR LT cir-
cuit breakers.
