Instrument panel flood lighting consists of four red lights on the
underside of the glare shield, and two red flood lights in the forward section
of the overhead console. This lighting is controlled by rotating the outer
knob labeled FLOOD, on the left dimming rheostat, clockwise to the
desired intensity.
The instrument panel may be equipped with post lights which are
mounted at the edge of each instrument or control and provide direct
lighting. The lighting is controlled by rotating the inner knob labeled
POST, on the left dimming rheostat, clockwise to the desired light inten-
sity. Flood and post lights may be used simultaneously by rotating both the
FLOOD and POST knobs clockwise to the desired intensity for each type of
lighting.
The engine instrument cluster, radio equipment, and magnetic com-
pass have integral lighting and operate independently of post or flood
lighting. To operate these lights, rotate the outer knob labeled ENG-
RADIO, on the right dimming rheostat, clockwise to the desired intensity.
However, for daylight operation, the compass and engine instrument
lights may be turned off while still maintaining maximum light intensity
for the digital readouts in the radio equipment. This is accomplished by
rotating the ENG-RADIO knob full counterclockwise. Check that the flood
lights, post lights, and electroluminescent lights are turned off for day-
light operation by rotating the FLOOD, POST, and EL PANEL knobs full
counterclockwise.
The control pedestal has two post lights and,
if
the airplane is
equipped
with oxygen, the overhead console is illuminated by post lights. Pedestal
and console light intensity is controlled by the knob labeled ENG-RADIO,
on the right dimming rheostat.
Map lighting is provided by overhead console map lights and a glare
shield mounted map light. The overhead console map lights operate in
conjunction with instrument panel flood lighting and consist of two
openings just aft of the red instrument panel flood lights. The map light
openings have sliding covers controlled by small round knobs which
uncover the openings when moved toward each other. The covers should be
kept closed unless the map lights are required. A map light and toggle
switch, mounted in front of the pilot on the underside of the glare shield is
used for illuminating approach plates or other charts when using a control
wheel mounted approach plate holder. The switch is labeled MAP LIGHT,
ON, OFF and light intensity is controlled by the knob labeled FLOOD, on
the left dimming rheostat. The pilot's control wheel map light (if installed)
illuminates the lower portion of the cabin in front of the pilot, and is used
for checking maps and other flight data during night operation. The light is
utilized by turning the NAV light switch to the ON position and adjusting
light intensity with the rheostat control knob on the bottom of the control
