Noise Characteristics/Abatement
The certificated noise levels for the aircraft established in accordance
with FAR 36 Appendix G are:
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 above noise levels were established at 3600 pounds takeoff
weight and 2500 RPM.
Recently, increased emphasis on improving environmental quality
requires all pilots to minimize the effect of airplane noise on the public.
The following suggested procedures minimize environmental noise
when operating the aircraft.
• Note •
Do not follow these noise abatement procedures where they
conflict with Air Traffic Control clearances or instructions,
weather considerations, or wherever they would reduce safety.
1. When operating VFR over noise-sensitive areas, such as outdoor
events, parks, and recreational areas, fly not less than 2000 feet
above the surface even though flight at a lower level may be
allowed.
2. For departure from or approach to an airport, avoid prolonged
flight at low altitude near noise-sensitive areas.
Fuel Conservation
Minimum fuel use at cruise will be achieved using Lean-of-Peak
Cruise Climb.
