External AC power Annunciator.
The annunciator placarded EXT AC PWR ON, located
in the mission annunciator panel (fig. 4-1), indicates that
external AC power is connected to the 3 phase busses.
The EXTERNAL POWER annunciator in the advisory
annunciator panel indicates that an AC GPU plug is
mated to the AC external power receptacle.

controls application of three phase AC power to the
Section X. LIGHTING
EXTERIOR LIGHTING .
Description. Exterior lighting (fig. 2-30)
consists of: a navigation light on the aft end of the aft
portion of the vertical stabilizer; one standard navigation
light on the outside of each wing tip pod; two strobe
beacons, one on top of the horizontal stabilizer (directly
above the vertical stabilizer) and one on the underside
of the fuselage section; dual landing lights and a taxi
light mounted on the nose gear assembly; a recognition
light located in the outboard leading edge of each wing;
two ice lights, one light flush mounted in each nacelle
positioned to illuminate along the leading edge of each
outboard wing; and emergency exit lights aft of the
escape hatch and aft of the cabin door.
Navigation Lights. The navigation lights
are protected by the 5-ampere circuit breaker placarded
NAV on the overhead circuit breaker panel (fig. 2-6).
Control of the lights is provided by the switch placarded
NAV ON, located in the overhead control panel (fig. 2-
Strobe Beacons. The strobe beacons
are dual intensity units. They are protected by the 15-
ampere circuit breaker placarded BCN on the overhead
circuit breaker panel (fig. 2-6). Control of the lights is
provided by the switch located in the overhead control
panel placarded BEACON DAY NIGHT (fig. 2-13).
Placing the switch in the DAY position will activate the
high intensity white section of the strobe lights for
greater visibility during daylight operation. Placing the
switch in the NIGHT position activates the lower
intensity red portion of the strobe lights.
Recognition Lights. The recognition
lights, which are normally used in the traffic pattern, are
operated by the two-position switch placarded RECOG,
located in the pilot's subpanel. The lights provide a very
bright, steady illumination. They are protected by a 7.
5-ampere circuit breaker, located in the overhead circuit
Landing/Taxi Lights. Dual landing lights
and a single taxi light are mounted on the nose gear
assembly. The lights are controlled by the switches
placarded LANDING and TAXI, located in the pilot's
subpanel. The landing light circuit its protected by the
5-ampere circuit breaker placarded LANDING, located
in the overhead circuit breaker panel (fig. 2-6). The taxi
light circuit is protected by a 5-ampere circuit breaker
placarded TAXI, located in the overhead circuit breaker
panel (fig. 2-6). Landing/Taxi lights are automatically
turned off when the landing gear is retracted. The
landing lights and taxi light power circuits are protected
respectively, located in the DC power distribution panel,
beneath the aisleway forward of the wing main spar.
Ice Lights. The ice lights circuit is
protected by the 5-ampere circuit breaker placarded ICE
on the overhead circuit breaker panel (fig. 2-6). Control
of the lights is provided by the switch placarded ICE ON
on the overhead control panel (fig. 2-13).
2-76. INTERIOR LIGHTING.
Lighting systems are installed for use by the
pilot and copilot. The lighting systems in the cockpit,
are provided with intensity controls on the overhead
control panel. The switch placarded MASTER ON,
located in the overhead control panel in the COCKPIT
LIGHTING section (fig. 2-13), provides overall control
for all engine instrument lights, pilot and copilot
instrument lights, overhead panel lights, and subpanel
lights. The switch placarded IR FLOOD ON, located on
the overhead control panel adjacent to the MASTER ON
switch (fig. 2-13), provides overall control for instrument
panel, glareshield, and pedestal extension/cockpit lights.
Utility lights. Two utility lights
are located in the cockpit overhead to provide additional
instrument panel IR lighting, as required. The lights are
