4-6 NOISE CHARACTERISTICS

An effort should be made to minimize the adverse effect of airplane noise
on the public. As pilots, we have the opportunity to build public support for
aviation and demonstrate our concern for improving the environment. United
application of the following suggested procedures can be the first step in
conquering the barriers between the aviation community and the general
public.
1. Pilots operating aircraft under VFR, over noise sensitive areas such
as outdoor assemblies and recreational park areas, should, weather
permitting, make every effort to not fly less than 2000 feet above ground
level, even though the federal regulations permit such operations.
2. While operating in and out of airports, climbs and descents should be
made in a manner as to avoid prolonged flight at low altitudes near noise-
sensitive areas.
3. Shortly after takeoff, power and propeller RPM should be reduced to allow
for quieter engine/propeller operation.
4. Whenever published traffic patterns and noise abatement procedures exist,
those procedures should be followed, while not compromising the safety of
the flight.
NOTE :
The above recommended procedures do not apply where they
would interfere with air traffic control clearances, or otherwise cause an
adverse affect on the safety of the flight.
The corrected noise level of this airplane with a gross weight of 7255 lb
is 82.5 dB without the external cargo compartment and 83.3 dB with the
external cargo compartment, determined by flight tests when operated at
takeoff/maximum continuous power (1790 ft lb torque at 2200 RPM). No
determination has been made by the Federal Aviation Administration that the
noise levels of this airplane are or should be acceptable for operation at, into,
or out of any airport.
The above statement notwithstanding, the noise level stated above has
been verified by and approved by the Federal Aviation Administration in
noise level flight tests conducted in accordance with FAR Part 36, Appendix
G, Amendment 28, Noise Standards: Airplane Type and Airworthiness
Certification. The airplane noise is in compliance with all FAR Part 36 noise
standards applicable to this type.
