NOISE CHARACTERISTICS.
AND NOISE REDUCTION
"The certificated nois~ level for the Model 172S at 2550 pounds
maximum weight is 75.1 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.
The following procedures are suggested to minimize the effect of
airplane noise on the public: "
1. Pilots operating airplanes 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 to adequately exercise the
duty to see and avoid other airplanes.
