Noise Certification Standards for Tiltrotors

Noise Certification Standards for Tiltrotors 10 Jan, 13, Source: HAI

A new rule amends the regulations governing noise certification standards for issuing type and airworthiness certificates for the civil, hybrid airplane-rotorcraft known as the tiltrotor.

This noise standard establishes new noise limits and procedures as the basis to ensure consistent aviation noise reduction technology is incorporated in tiltrotors for environmental protection. It provides uniform noise certification standards for tiltrotors certificated in the United States and harmonizes the U.S. regulations with the standards of the International Civil Aviation Organization’s (ICAO) Annex 16.

Editor note – this document is not specifically aimed at the AW609, but we have chosen that type to illustrate this piece as it is the only tiltrotor program heading for FAA certification in the next few years
