Maximum distance and altitude separation from noise-sensitive areas are the most effective means of noise abatement. Control movement should be gradual and smooth.

Noise exposure is:

  • lower on the right at high power settings
  • lower forward and on the left when hovering

To improve the quality of our environment and to dissuade the public from enacting overly restrictive ordinances against helicopters, it is imperative that every pilot produce the lowest possible noise irritation to the general public while flying. The following are several quieting techniques, which should be employed when possible.

Avoid flying over outdoor concerts, ball games, or other assemblies of people. When this cannot be avoided, fly as high as practicable, preferably over 2000 AGL.
