CESSNA SECTION 7
MODEL 182T AIRPLANE & SYSTEMS DESCRIPTION
An oil dipstick/filler tube is located on the upper left side of the
engine case. The dipstick and oil filler tube are accessed through a
door located on the left center portion of the upper engine cowling.
The engine should not be operated on less than four quarts of oil.
To minimize loss of oil through the breather, fill to eight quarts for
normal flights of less than three hours. For extended flight, fill to
nine quarts (dipstick indication only). For engine oil grade and
specifications, refer to Section 8 of this handbook.
IGNITION AND STARTER SYSTEM
Engine ignition is provided by two engine-driven magnetos, and
two spark plugs in each cylinder. The right magneto fires the lower
right and upper left spark plugs, and the left magneto fires the lower
left and upper right spark plugs. Normal operation is conducted with
both magnetos due to the more complete burning of the fuel/air
mixture with dual ignition.
Ignition and starter operation is controlled by a rotary-type switch
located on the left switch and control panel. The switch is labeled
clockwise, OFF, R, L, BOTH, and START. The engine should be
operated on both magnetos (BOTH position) except for magneto
checks. The R and L positions are for checking purposes and
emergency use only. When the switch is rotated to the START
position, (with the master switch in the ON position), the starter
contactor is closed and the starter, now energized, will crank the
engine. When the switch is released, it will automatically return to
the BOTH position.
AIR INDUCTION SYSTEM
The engine air induction system receives ram air through an
intake on the lower front portion of the engine cowling. The intake is
covered by an air filter which removes dust and other foreign matter
from the induction air. Airflow passing through the filter enters an air
box. The air box has one spring-loaded alternate air door. If the air
induction filter should become blocked, suction created by the
engine will open the door and draw unfiltered air from inside the
lower cowl area. An open alternate air door will result in an
approximate 10% power loss at full throttle. After passing through
the air box, induction air enters a fuel/air control unit under the
engine, and is then ducted to the engine cylinders through intake
manifold tubes.
