Acoustics/Environmental

The Acoustics/Environmental Committee is composed of Association members whose objective is to review all matters related to helicopters and heliport acoustics. This committee serves as the "Noise Task Force" of the Regulations Committee. Serving in this capacity, the committee provides technical and political advice for the development of association positions on government and/or community aeronautical acoustics standards and regulations that affect the civil helicopter industry.

HAI has :

  • Refined a "Fly Higher Chart" for distribution to helicopter operators. The Chart displays the acoustic benefits of flying higher, where doubling the altitude reduces the noise thate reaches the ground by more than half.
  • Reviewed the Congressionally mandated FAA study on "Non-Military Helicopter Noise," providing significant input and peer review for the FAA.
  • Prepared HAI inputs on proposed ICAO noise stringency for new design helicopters and derivatives.
  • Participated in the preparation and review of a proposed "Helicopter Model Ordinance".
