2120-AL29 202510 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2120 Federal Aviation Administration FAA 2100 Department of Transportation DOT Domestic Noise Certification of Supersonic Aircraft

This action would add new supersonic airplanes to the applicability of noise certification regulations, establish a standard for supersonic aircraft noise certification under 14 CFR Part 36, amend 14 CFR 91.817, and repeal 14 CFR 91.819 and 91.821. The proposed rule would (i) define acceptable noise thresholds for takeoff, landing, and in-route supersonic operation, and (ii) include a process for periodic review and update of the rule to reflect future advances in aircraft noise reduction technology.
