Incandescent Lighting
Incandescent lighting consists of floor lights
and map reading lights. Floor lights are sup-
plied from 28-VDC bus 1. Control switches are
located on the pilot's and copilot's side light-
ing panels. Illumination is provided for each
pilot in the area of the rudder pedals.
Map reading lights are located on either side
of the overhead panel. The lights are individ-
ually adjustable for direction and intensity.
The intensity of each light is controlled with
individual rheostats located on the overhead
lighting panel. Both map lights are powered
from the battery bus with the R map light hav-
ing DC Bus 2 as a redundant power supply.
Panel Lighting
Panel lighting is of two types: Fluorescent
and integral.
Fluorescent flood lighting is provided along
the glareshield to illuminate the center instru-
ment panel, pilot and copilot instrument panels,
side panels, fascia panels, and side consoles.
Each instrument panel and side console has
two fluorescent strip lights, while side pan-
els have only a single strip each. One of the
light strips for each instrument panel and both
lights for each side console are controlled
with a BRT-OFF-DIM switch. The other light
for each instrument panel is controlled with
a potentiometer.
The controls for the floodlights are located on
the center pedestal. Side console floodlight con-
trols are located on the associated fascia panel.
Power for the pilot's floodlights is supplied
from the DC essential bus. The copilot's flood-
lights are powered from the battery bus.
Integral lighting includes edge-lit panel light-
ing and instrument lighting.
CL-600-2B16 PILOT TRAINING MANUAL
The integral lighting in the cockpit is con-
trolled in two individual areas:
Integral lighting is supplied with up to 5 VAC
by incandescent lamp dimmers controlled
from the various lighting panels.
Overhead Panel
Under normal conditions, the overhead panel
lighting is supplied with 5 VAC stepped down
from AC bus 2. In the event that AC bus 2 is
not powered, such as before the APU is
started, the overhead panel receives power
from the battery bus through a DC incan-
descent lamp dimmer.
Normal intensity of the overhead panel light-
ing is controlled with a potentiometer located
on the cabin and miscellaneous lighting panel.
Left and right battery bus circuit-breaker panel
lighting is also controlled with the overhead
panel supply.
Center Instrument and Center
Pedestal Panels
The center instrument panel, center pedestal,
and main buses 1 and 2 circuit-breaker panels
are supplied with 5 VAC stepped down from
the AC essential bus. Intensity of this lighting
is controlled with a potentiometer located on
the center pedestal lighting control panel.
Pilot and Copilot Panels
The pilot instrument panel, side panel, fascia,
side console, and AC essential bus circuit-
breaker panel use 5 VAC stepped down from the
AC essential bus. The copilot panels, includ-
ing the DC essential bus circuit-breaker panel,
use 5 VAC stepped down from AC bus 2.
The intensity of pilot and copilot lighting is con-
trolled with a potentiometer on the associated
side panel of the center pedestal panel.
