Airflow Selection
The airflow selector on the system control panel regulates the volume
of airflow allowed into the cabin distribution system. When the airflow
selector is moved to the ON position an electro-mechanical linkage
actuates a butterfly valve in the mixing chamber on the forward firewall
to the full open position. The air is then distributed by either ram air or
by an optional blower fan to the distribution manifold mounted to the
center, aft side of the firewall
Vent Selection
Conditioned air from the distribution manifold can be proportioned and
directed to passengers and/or the windshield by manipulating the
cabin vent selector. The selector is mechanically linked to butterfly
valves at the entrances to the windshield diffuser and the cabin floor
ducting. There is continuous airflow to the panel and armrest eyeball
outlets. Each occupant can control the flow rate from 'off' to maximum
by rotating the nozzle.
When the selector is in the far left position, both butterfly valves are
closed providing maximum airflow to the panel and armrest eyeball
outlets. Rotating the selector a quarter-turn clockwise opens the cabin
floor butterfly valve allowing airflow to the rear seat foot warmer
diffusers and the front seat outlets mounted to the underside of each
kickplate. Rotating the selector another quarter-turn clockwise opens
the windshield diffuser butterfly valve which permits shared airflow to
the defrosting mechanism and cabin floor outlets. When the selector is
in the far right position, the cabin floor butterfly valve is closed
providing maximum airflow to the windshield diffuser.
Temperature Selection
The temperature selector is mechanically linked to the hot and cold air
valves. Rotating the selector simultaneously opens and closes the two
valves, permitting hot and cold air to mix and enter the distribution
system. Rotating the selector clockwise, permits warmer air to enter
the system - counterclockwise, cooler air.

Tire Inflation
Inflate nose tire to 30 psi (207 kPa) and main wheel tires to 62 psi
(427kPa).
Filling Fuel Tanks
Observe all safety precautions required when handling gasoline. Fuel
fillers are located on the forward slope of the wing. Each wing holds a
maximum of 46.0 U.S. gallons. When using less than the standard
92.0 U.S. gallon capacity, fuel should be distributed equally between
each side.
