OVERVIEW
The aircraft utility systems are the systems that are not critical to flight. The heat
system enables the occupants to control the cockpit temperature with a push/pull cable.
Hot air diverted from the heat exchangers provides cockpit heat. Cabin ventilation air
can be controlled with either of the two vents, one on each side of the fuselage.

Air that passes through the engine coolant heat exchanger is heated. The heated
air continues into the cooler box. A push / pull cable controls a door in the cooler box
that diverts the heated air into, or away from the cockpit.
