The cabin interior is ventilated with ambient ram air. The ram air enters an inlet scoop
on the roof, which is controlled by a lever above the pilot's head, and is directed through
a plenum into two parallel distribution ducts. Four dual outlets are installed in the
passenger compartment headliner (combined with the four cabin lights), with two
additional outlets just above the windshields in front of the pilot and forward passenger.
Each of the outlets is separately controllable in direction and volume. Air exhausts
from the cabin through two ports, left and right, near the floor, at the lower edge of the
rear bench seat. The ports may be opened or closed by hand to help adjust the flow.
The minimum cabin air exchange rate in cruise flight is 2.83 cubic meters per minute
(100 cubic feet per minute).
