MODEL
2. During departure from or approach to an airport, climb after take-
off and descent for landing should be made so as to avoid prolonged
flight at low altitude near noise-sensitive areas. Avoidance of
noise-sensitive areas, if practical, is preferable to overflight at
relatively low altitudes .
.--------NOTE----------.
The preceding 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 his duty to see and
avoid other airplanes.
The flyover noise level, established in compliance with FAR 36, is 75.1
dB(A) .
No determination has been made by the Federal Aviation Administration
that the noise level of this airplane is, or should be acceptable or
unacceptable, for operation at, into, or out of any airport.
