Section X. LIGHTING
2-85. EXTERIOR LIGHTING.
a. Description. Exterior lighting consists of a
navigation light on the aft top of the vertical stabilizer,
one navigation light on each wing tip, two strobe
beacons, one on top of the vertical stabilizer and one
on the underside of the fuselage center section, one
combination landing/taxi light recess mounted in each
wing tip C , or dual landing lights and one taxi light
mounted on the nose gear assembly D T , and two
ice lights, one light flush mounted in each nacelle,
positioned to illuminate along the leading edge of each
outboard wing. In addition, some aircraft are equipped
with a recognition light located in each wing tip. Refer
to Figure 2-30.
b. Navigation Lights. The navigation lights are
protected by a 5 -ampere circuit breaker, placarded
NAV, on the overhead circuit breaker panel. The
lights are controlled by a switch, placarded NAV ON,
on the overhead control panel.
c. Strobe Beacons. The strobe beacons are
dual intensity units. They are protected by a
15-ampere circuit breaker placarded BCN on the
overhead circuit breaker panel. Control of the lights is
provided by a switch placarded BEACON DAY
NIGHT. Placing the switch in the DAY position will
activate the high intensity white section of the strobe
lights for greater visibility during daytime operation.
Placing the switch in the NIGHT position activates the
lower intensity red section of the strobe lights.
d. Landing/Taxi Lights. Dual landing lights
and a single taxi light are mounted on the nose gear
assembly. The lights are controlled by switches
placarded LANDING and TAXI located in the LIGHTS
section of the pilot's subpanel. The control circuits are
protected by two 5-ampere circuit breakers placarded
LANDING LIGHT TAXI LDG on the overhead circuit
breaker panel. The landing lights and taxi light power
circuits are protected by 35-ampere and 15-ampere
circuit breakers, respectively, located on the dc power
distribution panel beneath the cockpit floor.
e. Ice Lights. The ice lights are protected by a
5-ampere circuit breaker, placarded ICE, on the
overhead circuit breaker panel. The lights are
controlled by a switch, placarded ICE ON, on the
overhead control panel. Prolonged use during ground
operation may generate enough heat to damage the
f. Recognition Lights. A RECOG switch,
located in the pilot's subpanel LIGHTS section,
controls a white recognition light in each wing tip. This
steady bright light is used for identification. The
system is protected by a 7.5-ampere RECOG circuit
breaker located on the overhead circuit breaker panel.
2-86. INTERIOR LIGHTS.
(1) Interior Lighting C D T1 . Lighting
systems are installed for use by the pilot and copilot
and by the passengers in the cabin area. The lighting
systems in the cockpit are provided with intensity
controls on the overhead control panel. A switch,
placarded MASTER PANEL LIGHTS, on the overhead
control panel, provides overall on-off control for all
engine instrument lights, pilot and copilot instrument
lights, overhead panel lights, console and subpanel.
(2) Interior Lighting T2 . Aviation Night
Vision (ANVIS) compatible lighting is installed in the
cockpit and cabin area. The cockpit lighting systems
are provided with individually controlled, from OFF to
BRT (bright) rheostats on the overhead control panel.
Cabin lighting is controlled by two switches, placarded
CABIN LIGHT ON / BRIGHT and READING LIGHT
A switch, placarded MASTER PANEL LIGHTS,
on the overhead control panel provides an overall
power on-off control for all engine instrument lights,
pilot and copilot instrument and gyro instrument lights,
instrument indirect lights, overhead flood lights,
