7.15 Supplementary Equipment
7.15.1 Stall Speed Warning System
The sensor of stall speed warning is located on the left wing leading edge. When
approaching the critical angle of attack (stall speed proximity) the flap is reset
and electrical circuit connected as a result of pressure differences acting on the
front and the rear part of the flap. During stall speed warning the acoustic
signaling is activated which lasts throughout the time of occurrence.
7.15.2 Ventilation and Heating System
Cockpit ventilation is ensured by 2 eye–ball vents located on the left and right of
the tip-up canopy frame. Vents are connected to the NACA scoops through tip-
up canopy frame front flaps.
Cockpit heating is ensured by hot air from the heat exchanger. The heat
exchanger is located on the exhaust pipe collector. Air from ambient atmosphere
is warmed up in the exhaust pipe collector and then led through the mixture flap
on the firewall and further through a directional flap to the cockpit floor or to the
hot air outputs through the instrument panel cover as well as into the hollow
spaces in the canopy frame for canopy glass defrosting.
Hot air quantity is regulated by the hot air knob (
HEIZUG
)
, cold air quantity is
regulated by the cold air knob (
KALTLUFT
) located below the instrument panel.
Proportion of the cold and hot air in the heating system can be set continuously.
Other knob above the the cold air knob (
KALTLUFT
) serves for air routing to the
cockpit floor or on the canopy glass.
