Description and operation
13.2.1
Venting system
Cockpit ventilation is ensured by two regulated air vents located on the cockpit sides under
the instrument panel (see Fig.13-5). NACA type air inlets are located on the fuselage sides in
front of the canopy frame. Quantity of inlet air is controlled by flaps which are movable in all
directions which allow adjusting the air volume and air flow direction together. It is also
possible to ventilate the cabin through sliding side windows located on the canopy (if
installed).

13.2.2.1 Standard heating system
Cockpit heating is ensured by hot air from the heat exchanger. The heat exchanger (1, Fig. 13-

exchanger (1) and supplied through control flap (3) into the cockpit by air hoses (4). Quantity
of hot air is regulated by
