INTERIOR LIGHTING
Interior lighting is controlled by a combination of dimmable crew area
flood lighting, internally lit switch and circuit breaker panels, avionics
panel lighting, standby instrument lighting, pedestal lighting, pilot
control wheel map lighting and passenger area flood lighting.
For airplanes serials 172S9810 thru 172S10102, flood lighting is
accomplished using one dimmable light in the front crew area and one
dome light in the rear passenger area. These lights are contained in the
overhead console, and are controlled by either the dimmer control for
the front flood light, and an on-off type push button switch for the rear
dome light. The front lights can be rotated to provide directional lighting
for the pilot and front passenger. The rear dome light provides for
general illumination in the rear cabin area. Rear dome light and
courtesy lights, located under the wing, share the same control switch.
For airplanes serials 172S10103 thru 172S10467 and 172S10469 thru
172S10506 and 172S10508 thru 172S10639 and 172S10641 thru
172S10655, flood lighting is accomplished using two dimmable lights in
the front crew area and one dome light in the rear passenger area.
These lights are contained in the overhead console, and are controlled
by dimmer controls for the front flood lights, and an on-off type push
button switch for the rear dome light. The front flood lights can be
rotated to provide directional lighting for the pilot and front passenger.
The rear dome light provides for general illumination in the rear cabin
area. Rear dome light and courtesy lights, located under the wing,
share the same control switch.
Lighting of the switch panel, circuit breaker panel, engine controls and
environmental control panel is accomplished by using internally lit LED
panels. Rotating the SW/CB PANELS dimmer, found on the switch
panel in the DIMMING group, controls the lighting level for both panels.
Rotating the dimmer counterclockwise decreases light intensity from
the highest level to off.
Pedestal lighting consists of two hooded lights found at various
locations on the pedestal. Rotating the PEDESTAL light dimmer, found
on the switch panel in the DIMMING group, controls the pedestal lights.
Rotating the dimmer counterclockwise decreases light intensity from
the highest level to off.
