AIR INDUCTION SYSTEM
The engine air induction system receives ram air through the engine
air intakes located on the top of the cowling. The air is then routed to a
plenum chamber where the compressor inlet bellmouth is located.
The engine air plenum is protected by a screen, which will prevent
entry of large articles, but does not filter the inlet air.
ENGINE INLET ANTI-ICE
The engine anti-ice must be actuated during operations below an
OAT of 5°C (41°F) or in falling or blowing snow. Turning the “T”
handle counter-clockwise to unlock the control, then pulling the
handle all of the way out operates the inlet anti-ice. With the
handle out, turn it clockwise to lock the control in the ON position.
ENGINE ALTERNATE AIR
An alternate air system is built into the intake system to prevent
moisture particles from entering the engine inlet plenum. It
consists of two ram inlet doors and a cowl ventilation door that are
pneumatically operated by bleed air and a spring-loaded alternate
air door on the plenum chamber.
During normal operation of the engine air system, the movable
ram inlet doors are retracted out of the direct ram air inlet. For
cold weather operation of 1
C (34
F) or below in visible moisture,
or while operating in falling or blowing snow, the doors should be
raised to block the ram air inlet. Suction created by the engine
will open the spring-loaded alternate air door on the back of the
plenum and draw air from inside the engine cowl area.
Additionally, a door on the underside of the cowling will open to
help supply the engine cowl area with cool air.
The engine alternate air system is operated by an alternate air
control lever on the right side of the control pedestal. The
pedestal is labeled NORM, ALT AIR, ALT. The system is
operated by moving the lever to the right to clear a detent, then
moving the lever all the way up to the NORM position.
