CABIN LIGHTING
General
Passenger compartment lighting consists of
reading lights, overhead lights, entry lights,
and No Smoking/Fasten Seat Belt signs.
Upper Central Panel Lights
Two upper center panel lights are installed
and controlled by the switch on the left serv-
ice cabinet (Figure 3-3). The lights are pow-
ered through the ENT LTS and CAB LTS
circuit breakers.
Entry Light
The entry light, installed in the left service cab-
inet, is controlled by the switch on the left serv-
ice cabinet. The light is powered through the
ENT LTS circuit breaker. Battery power is
available to the light even when the battery
switches are turned off.
No Smoking/Fasten Seat Belt
Sign
The lights are located on the aft side of the left
service cabinet (Figure 3-4) and are controlled
by a switch on the pedestal. In addition to en-
ergizing the lights, the control switch applies
28 VDC to the tone generator, which produces
an audible tone through the aft cabin speaker.
The lights are powered through the CAB LTS
circuit breaker.
Baggage Compartment Lights
Two baggage compartment lights are installed
in the airplane. They are located in the head-
liner of the baggage compartment. The lights
are controlled by the switch located on the
