tests the warning lights; turning the lens housings dims
them.
CABIN LIGHTING
The rheostat knobs in the headliner control instrument
lights, overhead spot lights, and the compass light. Rota-
ting the knob clockwise turns on and increases light inten-
sity. An overhead dome light illuminates the cabin.
HEATING
&
VENTILATING
SYSTEMS
Three ventilating systems provide cabin environmental con-
trol suited to individual pilot and passenger preferences.
Heated air from the engine exhaust muffler and cool air
from an
airscoop on the co-pilot side
is
individually con-
trolled and mixed to the desired temperature. The distri-
bution duct system directs air to the pilot and co-pilot and
to the
aftcabin area. Valves or louvers at the vent system
outlets control airflow. The left side fresh-air scoop has
an adjustable eyeball inlet.
The cabin overhead ventilating system works independently
of the cabin heating and ventilating system. Rotating the
knob above the pilot seat extends or retracts the overhead
airscoop to control air intake and to prevent air-buffeting
at high cruising speeds. Small directional vent deflectors
withinner knob volume controls, within easy reach of each
occupant, distribute incoming outside
air
as
individually
desired.
The cabin heat control is marked
CABIN
HEAT. Opening
the side
airscoop control (labeled
CABIN
VENT)
and setting
the cabin heat control turns on cabin heat. To lower cabin
