General

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.

Takeoff and Climb

  • Accelerate to 60 knots as quickly as possible.
  • Climb at a high rate of climb in order to reach altitude as soon as possible.

Enroute and Cruise Flyover

  • When possible, maintain a minimum altitude of 500 feet above ground level.
  • Repetitive noise is far more irritating than a single occurrence. If you must fly over the same area more than once, vary your flight path so that you do not over-fly the same buildings each time.

Descent/Approach and Landing

Near noise-sensitive areas, use 60 knots as the minimum airspeed. Use a steep approach.

When departing from or approaching a landing site, avoid prolonged flight over residential neighborhoods, schools, hospitals and other noise sensitive areas. Always fly above 500 feet AGL and preferably above 1000 AGL.


Comments

When over flying populated areas look ahead and select the least noise sensitive route. Avoid blade slap when flying over noise-sensitive areas.


HAI Comment

The minimum enroute and cruise flyover height information given is less than that recommended by HAI in the 'Fly High Chart' which suggests, when practical, a minimum height of 1000ft for the R22.
