7.23 HEATING AND VENTILATING SYSTEM
Heat for the cabin interior and the defroster system (Figure 7-17) is
provided by a shroud attached to the mufflers. Fumes in the cockpit could
be an indication of an exhaust leak; therefore, if unusual odors are detected,
the heater should be turned off and the system inspected before further
operation. The amount of heat and the routing of airflow can be regulated
with the controls located on the left instrument panel. Heater air may be
directed to the outlets in the lower firewall below the instrument panel and
the ducts mounted along the center tunnel on the right and left cockpit floor
or to defroster outlets at the base of the windshield.
Fresh air intakes are located on each side of the fuselage in the area aft of
the engine cowling. Adjustable outlets on each lower corner of the
instrument panel allow fresh air to be admitted and directed. An on-off lever
is mounted below each fresh air outlet.
7.25 CABIN FEATURES
For comfort and visibility, the seats are adjustable forward and aft. The
seat tracks are inclined and provide automatic vertical adjustment; the seat
is raised in the forward position and lowered in the aft position. The seat
adjustment levers are on the centers of the seat frames just below the forward
edges of the cushions. Both seat backs tilt forward to allow access to the
baggage compartment.
Safety belts are standard equipment on both seats. Interia reels for the
shoulder straps are offered as optional equipment. For normal body
movements, the inertia reel extends or retracts as required, but during
sudden forward movement, the reel locks in place to prevent the strap from
extending.
Standard interior equipment includes a pilot storm window, door pulls
with integral armrests, a glare shield, an ash tray, and a carpeted floor. The
microphone and earphone jacks are between the seats on the center console.
A tinted rear window is also standard equipment. Standard equipment on
later model aircraft incorporates a glare shield with hand holds and side
panel map pockets.
Each cabin door has an interior latch below the side window. The latch
is engaged when the handle is in the down position. The overhead latch in
the center of the cockpit secures both doors (Figure 7-19) Before flight, the
