Some aircraft are equipped with ground adjustable cowl
flaps on the lower cowl. Remove the lower cowl from the
aircraft to adjust the flaps as necessary, ensuring all
attachment fasteners are retightened.
7.5.5 EXHAUST SYSTEM
The exhaust system is made of stainless steel. It is
covered with a shroud that is used as a heat exchanger
to draw hot air for the cabin and for the induction system.
7.5.6 IGNITION SYSTEM
Ignition is provided by Two independent magnetos. The
pilot must ensure that both magnetos are operating
correctly prior to takeoff. In an emergency, the engine
will continue to run if one of the magnetos fails. The
engine should be started with the ignition switch in the
BOTH position.
7.5.7 AIR INDUCTION SYSTEM
The induction air for the engine enters through a filter on
the lower side of the cowling. Alternatively, the pilot may
use the carburetor heat control which operates a butterfly
valve allowing heated, unfiltered air into the carburetor.
The control is located on the instrument panel.
CAUTION
Ground operations with the carburetor heat control in
the hot position must be limited because of the fact
that air by-passes the filter.
Should the air filter become obstructed, the carburetor air
control provides an alternate means of supplying the
engine with air for the induction system.
