Study Notes

Cabin Ventilation and Cooling

Cabin ventilation and cooling are achieved solely through fresh air intake from the overhead vent system.
The overhead vent blower is located aft of the rear cabin close-out panel, underneath the fuselage top.
The blower is connected to the overhead vent system.
The vent blower draws in air from either the dorsal fin or a louver on the left rear side of the fuselage.
The drawn air is then forced through the ducting system.
A three-position blower switch is located on the instrument panel and controls the two-speed blower.
