INTERIOR LIGHTING
Interior lighting is controlled by a combination of dimmable crew
area flood lighting, internally illuminated switch and circuit breaker
panels, avionics panel lighting, instrument lighting, pedestal lighting,
pilot control wheel map lighting and passenger area flood lighting.
For airplane 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. Both lights are contained
in the overhead console, and are controlled by either the dimmer
control for the front light, and an on and off type push button switch
for the rear light. The front light 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 share the same switch.
For airplane serials 172S10103 and On, 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 lights, and an on and off type push button
switch for the rear 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 share the same switch.
Lighting of the switch panel, circuit breaker panel, engine controls
and environmental control panel is accomplished by using internally
lighted LED lighted 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 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.
