CESSNA AIRCRAFT COMPANY FOR TRAINING USE ONLY
MODEL 152 4-20
Without Preheat:
The procedure for starting without preheat is the same as with preheat except the engine should be
primed an additional three strokes just prior to pulling the propeller through by hand.
NOTE
If the engine fires but does not start or continue running, repeat the
above starting procedure beginning with step 6. If the engine does not
start during the first few attempts, or if engine firing diminishes in
strength, it is possible that the spark plugs have been frosted over, in
which case preheat must be used before another start is attempted.
During cold weather operations, no indication will be apparent on the oil temperature gage prior to
takeoff if outside air temperatures are very cold. After a suitable warm-up period (2 to 5 minutes at
1000 RPM), accelerate the engine several times to higher engine RPM. If the engine accelerates
smoothly and oil pressure remains normal and steady, the airplane is ready for takeoff.
When operating in temperatures below -18°C, avoid using partial carburetor heat. Partial heat may
increase the carburetor air temperature to the 0° to 21°C range, where icing is critical under certain
atmospheric conditions.
NOISE ABATEMENT
Increased emphasis on improving the quality of our environment requires renewed effort on the part of
all pilots to minimize the effect of airplane noise on the public.
We, as pilots, can demonstrate our concern for environmental improvement, by application of the
following suggested procedures, and thereby tend to build public support for aviation:
1. Pilots operating aircraft under VFR over outdoor assemblies of persons, recreational and park
areas, and other noise-sensitive areas should make every effort to fly not less than 2000 feet
above the surface, weather permitting, even though flight at a lower level may be consistent
with the provisions of government regulations.
2. During departure from or approach to an airport, climb after takeoff and descent for landing
should be made so as to avoid prolonged flight at low altitude near noise-sensitive areas.
NOTE
The above recommended procedures do not apply where they would
conflict with Air Traffic Control clearances or instructions, or where, in
the pilot’s judgment, an altitude of less than 2000 feet is necessary for
him to adequately exercise his duty to see and avoid other aircraft.
The certificated noise level for the Model 152 at 1670 pounds maximum weight is 65.0 dB(A). No
determination has been made by the Federal Aviation Administration that the noise levels of this
airplane are or should be acceptable or unacceptable for operation at, into or out of, any airport.
