FAA – April 13, 2020 – Published NPRM: Noise Certification of Supersonic Airplanes

Posted on April 13, 2020

Federal Register – A Proposed Rule by the Federal Aviation Administration on 04/13/2020

The document has also been posted to the SCSC Roundtable website here.

This action proposes to add new supersonic airplanes to the applicability of noise certification regulations, and proposes landing and takeoff noise standards for a certain class of new supersonic airplanes. There is renewed interest in the development of supersonic aircraft, and the proposed regulations would facilitate the continued development of airplanes by specifying the noise limits for the designs, providing the means to certificate the airplanes for subsonic operation in the United States.
