4-17. NOISE IMPACT REDUCTION PROCEDURES
Certain flight procedures are recommended to minimize noise impact
on surrounding areas. It is imperative that every pilot subject the
public to the least possible noise while operating the helicopter.
Takeoff:
Takeoff using maximum takeoff power at the speed for best rate of
climb (Fig. 5-1).
Proceed away from noise sensitive areas.
If takeoff must be made over noise sensitive area, distance (alti-
tude) is the best form of noise suppression.
Cruise:
Maintain 1000 feet minimum altitude (AGL) where possible.
Maintain speed of no more than 80 knots over populated areas.
Keep noise sensitive areas to left side of helicopter.
Coordinated turns at around the speed for best rate of climb
cause no appreciable change in noise.
Sharper turns reduce area exposed to noise.
Approach:
Use steepest glideslope consistent with passenger comfort and
safety.
Keep noise sensitive areas to left side of helicopter.
