NORMAL PROCEDURES

NOISE CHARACTERISTICS

The noise levels for the Model 208B Caravan EX, equipped with the
PT6A-140 engine are 84.1 dB(A). These levels were established using
test data obtained and analyzed under procedures of 14 CFR 36,
Amendment 28 and the equivalent procedures of International Civil
Aviation Organization (ICAO) Annex 16, Volume I, Sixth Edition,
Amendment 10. This airplane complies with Appendix G noise limits of
14 CFR 36 and Chapter 10 noise limits of ICAO Annex 16.
Noise levels were obtained at a maximum weight of 8807 pounds (3994
kg) with flaps set at TO/APR up to 50 feet, then a climb with flaps UP at
a speed of 108 KIAS and maximum power at 1900 RPM and 2397 FT
LB. 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 can 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.
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.
