Normal Procedures
NOISE
CHARACTERISTICS
Approach
to and
departure from
an airport 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 overflightat
relatively low
altitudes.
For VFR
operations over outdoor assemblies of persons,
recreational and park
areas, and other noise-sensitive
areas,
pilots
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.
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
judgement,
an altitude
of
less
than
2000 feet is
necessary to adequately
exercise
his duty
to see and
evoid
other
airplanes.
Flyover noise level
established
in
compliance
with FAR 36
is:
73.3
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.
