SYSTEM DESCRIPTION
On the left front engine baffle a 3” air intake (1, figure 1) with screen is positioned. From there fresh
air is routed through a 3" ducting (2) to the exhaust muffler heat shroud (3), where it is heated up.
A selector box (4) is placed on the engine side of the firewall. Using the main handle (9) the warm
air can there be guided into the cockpit or dumped overboard. A further selector box (5) is located
on the aft side of the firewall. Using the distribution handle (8) the ratio of warm air supply between
front and rear can be controlled there. The rear selector box incorporates the warm air dispensers
for the front occupant as well as the flange for the 2" ducting (6) to the air outlets (7) at the pilot’s
feet.
