PASSENGER CABIN LIGHTING
Passenger cabin lighting includes general illumination, reading lights,
lavatory, galley lights and cabin signs.
GENERAL PASSENGER CABIN ILLUMINATION
General passenger cabin illumination is provided by fluorescent tubes
fitted in the fuselage ceiling and sidewall. These lights are controlled
by control buttons located on the Attendant Panel.
READING LIGHTS
A separate reading light and control is provided above each passenger
seat, on the Passenger Service Unit (PSU). For PSU details, refer to
Section 2-2–Equipment and Furnishings.
LAVATORY
The lavatory lights are automatically controlled through a microswitch
installed in the latch assembly of the door. When the airplane is
powered up and the toilet door is open or closed, the lavatory lights
turn on in dim mode. If the toilet door is closed and locked, the lavatory
lights turn on in the bright mode.
Two illuminated LAVATORY OCCUPIED signs indicate when the
lavatory is in use. A RETURN TO SEAT sign in the lavatory illuminates
in conjunction with the FASTEN SEAT BELTS sign.
PASSENGER CABIN SIGNS
The passenger warning signs are illuminated signs that will be clearly
visible under normal daylight lighting conditions. They provide
passengers and flight attendants with NO SMOKING, FASTEN SEAT
BELTS, RETURN
instructions.
The NO SMOKING and FASTEN SEAT BELTS signs are controlled
through respective switches located on the overhead panel. The signs
are repeated on every Passenger Service Unit. An aural signal sounds
whenever any passenger sign is turned on or off by the pilot. The NO
SMOKING and FASTEN SEAT BELTS signs are also activated when
the oxygen dispensing units are open. For PSU details refer to Section
2-2–Equipment and Furnishings.
GALLEY LIGHT
The galley light illuminates the galley area between forward and aft
galleys. The light is controlled through two buttons, located on the
Galley Control Panel. For Galley Control Panel details refer to Section
2-2–Equipment and Furnishings.
