Predicted airframe noise levels for certification flights

Journal of Aircraft, 1981
A correction is presented for a previously published inconsistency in predicted airframe noise values, which were based on approach velocities lower than those required for FAA certification. New figures are given for the following aircraft: DC-9-30, 727-200, A300-B2, L-1011, DC-10-10, and 747-200B.

Alternative noise certification concepts for air carrier aircraft

The Journal of the Acoustical Society of America, 1980
This paper examines a number of general and specific concepts in noise certification. These include current takeoff and landing flight procedure requirements, and the potential role of static engine noise testing for noise certification. Effectiveness of existing noise certification concepts are briefly reviewed and alternative methods considered which

Noise Certification of UAS through Rules of Particular Applicability

When an applicant presents an unmanned aircraft system (UAS) or drone to the United States Federal Aviation Administration (FAA) for noise type certification, the FAA reviews the aircraft’s design and flight characteristics, and then determines if the current noise testing procedures and requirements in United States Code Title 14 part 36 apply to the ...
