7.19 Cabin Heating and Ventilation
Cabin heating and ventilation supply conditioned air for cabin heating/venting and windshield demist.
Cabin heating and venting air is provided by a control box and enters the cabin through the firewall. The air is received
from the deflector installed behind the water radiator and flows through the air hose to the heat exchanger on the
muffler to be heated. Heated air from the exchanger flows through the air hose to the control box. Fresh air is
received from the ram air tunnel installed on the left side of lower engine cowling and is directed through the air hose
to the control box.
The proportion of heated to fresh air is controllable by means of controllers labelled
CABIN HEATING and CABIN
VENTILATION (Fig. 7-4). The means of control is as follows: PULL to OPEN, PUSH to CLOSE.
There are venting windows on the both sides of the windshield (Fig. 7-28).
Fresh air for cabin venting and windshield demisting is received from the NACA intakes on both sides of the canopy.
The fresh air flows through the canopy frame and enters the cockpit through the air outlets on both sides of the
canopy. The air outlets control the amount and direction of air (Fig. 7-29).
The fresh air for windshield demisting flows through the holes located in the front section of canopy frame. The
amount of air is controlled by knobs on both sides of canopy (Fig. 7-30).
