FLIGHT COMPARTMENT - INTRODUCTION
Purpose
The flight compartment lighting supplies normal or
emergency lighting of critical and noncritical lighting
components. The lighting systems are controlled by the
panels shown.
The override light switch gives dome and flood lighting
for pilots if they are near lightning discharges. The
override light minimizes the vision loss if lightning lights
up the cockpit.
Physical Description
These lights are controlled by various switches mostly
on the P5 panel:
- Integral panel
- Switch
- Instrument.
Annunciator lights are controlled by the master dim and
test circuits.
Area lighting is given by these lights:
- Flood
- Dome
- Map.
Chart lights give lighting to letdown plate holders, and
utility lights (not shown) give lighting where necessary
because they are portable.

FLIGHT COMPARTMENT - DIMMER CONTROL
UNITS
Purpose
Panel and floodlight dimmer control units give starting
and dimming voltages for the fluorescent and
incandescent lights in the flight compartment.
Locations
The dimmer control units for the aisle stand are in the
aisle stand and under the floor adjacent to the aisle
stand. To get access to the units under the floor go
through the main equipment center.
Overhead panel dimmer units attach to the drip shield
on each side of the P5 panel and in the P11 circuit
breaker panels.
The right side panel has one light dimmer control unit.
Physical Description
The dimmer control unit has a rheostat that controls the
amount of voltage to the light. This voltage varies from
0 to 28 volts dc.
All dimmer units are interchangeable.

LIGHTS - UTILITY LIGHTS
Purpose
The utility lights give light from a portable light holder
and is either red or white light.
Physical Description
Incandescent flight kit and utility lights are at the
captain, first officer, and observer stations. They use
28v ac from the right bus on the P11 panel.
Release the portable lights from a mounting stand with
a snap release tensioner. Turn the front lens assembly
to select a red or white filter. Two switches and a
rheostat are built into the assembly. One switch is in
series with the rheostat. The other switch bypasses the
rheostat and gives maximum brightness when pushed.
The rotary rheostat control is on the back of the light
assembly.

FLIGHT COMPARTMENT - MASTER DIM AND TEST
CONTROL CARDS AND RELAYS
Purpose
The control cards and relays give light intensity control
to the master dim and test switches.
Location
The cards and relays are in the lighting control panel
(P29).
The panel is in the right side of the fuselage forward of
the main equipment center at station 200.
Functional Description
28v dc supplies power to the dimmer card. The output
power, 12v dc, from the power switching unit operates
the light/relay load circuit and turns on the light emitting
diode when the card is operational.

PASSENGER COMPARTMENT - CABIN
ATTENDANTS LIGHTING CONTROLS - FORWARD
Physical Description
The forward attendant panel has two three-position
rotary switches to supply light intensity control for the
forward and mid cabin lights.
The sidewall light switch three positions are OFF, DIM,
and BRIGHT. The ceiling light switch three positions
are N/L (night light), DIM, and BRIGHT. There is no
OFF position for the ceiling lights so the cabin lighting
can not be completely turned off by mistake. In the N/L
position, the night lights are on and fluorescent lamps
are off. In the DIM position, the night lights are off and
fluorescent lamps are dim. In the BRIGHT position, the
night lights are off and the fluorescent lamps are bright.
The ceiling light switch also controls the direct ceiling
lights.

LIGHTS - EXTERIOR - INTRODUCTION
Purpose
Airplane exterior lighting gives high intensity light for
identification of airplane position (navigation) and
orientation. It also gives lighting for landing and taxi
area, wings and engines. All lights are controlled from
the flight compartment.
Physical Description
Wing illumination lights are high intensity quartz
halogen light assemblies on each side of the fuselage.
A plano lens divides the light from one lamp into two
beams. One beam lights the engine and the other lights
the wing. A switch on the P5 overhead panel controls
both light assemblies.
Two high intensity landing lights are on the nose
landing gear. One high intensity landing light is in each
wing root strakelet. Each wing light and the nose gear
lights are controlled by separate switches on overhead
panel P5. Landing gear lever position switch changes
the brightness of the wing landing lights from dim to
bright when the landing gear is lowered. Another
similar switch turns on the nose gear landing lights
when the gear is down and locked
runway turnoff light in each wing root strakelet lights
the ground ahead and to the side of the airplane. Each
light is controlled by a separate switch on overhead
panel P5.
Quartz halogen position (navigation) light in the leading
and trailing edges of the wingtips give lighting to detect
airplane position. Trailing edge
lights are white. Left leading edge lights are red. Right
leading edge lights are green. A switch on the
overhead panel P5 controls all lights.
High intensity Xenon strobe lights on the fuselage and
wingtips flash 48 times-per-minute. The lights on the
fuselage are red and the wingtip lights are white.
Separate on/off switches on the P5 overhead panel
control the red and white lights.
Four logo lights in the horizontal stabilizer light the
vertical stabilizer and rudder. They are controlled by An
alternate action switch-light on the P5 overhead panel
controls these lights.
Runway turnoff and taxi lights are high intensity quartz
halogen lights. The taxi light, on the nose gear between
the wheels, lights the ground ahead of the airplane. A

EMERGENCY ILLUMINATION - INTRODUCTION
Purpose
The emergency lighting system gives a backup lighting
system if the airplane loses AC power.
Location
Primary control for the emergency lights is a guarded
three-position (ON/ARM/OFF) toggle switch on the P5
overhead panel. An ON/OFF control switch is on the
P21 forward attendant panel. There are three system
test switches; one on P21, one on P22 aft attendant
panel, and one on P40 APU ground control panel.
The interior lights are at these locations:
- Portable light assembly above the flight deck door in
the flight compartment
- Various types of lights in the ceiling area of the
passenger compartment
- Near the entry/service doors
- Near the emergency doors
- On the floor outboard of the aisles and in the cross
aisles.
The exterior lights are flush-mounted on the fuselage
aft of the doors.
Most of the battery packs (power supplies) for the
interior and exterior lights are outboard of the
removable air grilles throughout the cabin. Battery
packs may also be at the base of some attendant
seats.
Inverters for some cross aisle indicators are below
selected battery packs.
System control relays are in the P19 relay panel above
the passenger compartment ceiling.
Physical Description
The system has two primary subsystems, interior lights
that include the flight and passenger compartments
and exterior lights.
Incandescent lamps are used in all of the various types
of interior and exterior emergency lights with the
exception of some floor-mounted cross aisle indicators.
There are two types of cross aisle indicators, one that
uses incandescent lamps and one that is
electroluminescent. The electroluminescent lights are
in uncorrupted cross aisles.
There is one type of battery pack with the exception of
the battery pack for the emergency light in the flight
compartment. For this installation only, the battery pack
and light are in one assembly that can be removed and
used as a portable light. The batteries in each pack
charge when power is on the correct bus and the
