Measured or Estimated (Uncertificated) Airplane Noise Levels
Provides estimates of noise levels or measured noise levels from airplanes not certificated to FAR Part 36.
Noise Levels for U.S. Certificated and Foreign Aircraft
Provides noise level data for airplanes certificated under FAR Part 36. Noise level data for foreign airplanes certificated to ICAO Annex 16 standards are also provided in a separate appendix for informational purposes.
Estimated Airplane Noise Levels in A-Weighted Decibels
Provides listings of estimated airplane noise levels in units of A-weighted sound levels in decibels (dBA), ranked in describing order for the conditions and assumptions described. This information is provided both for aircraft that have been noise type certificated under 14 CFR Part 36 and for Aircraft for which no such requirement currently exists.
Noise Standards: Aircraft Type and Airworthiness Certification
Promotes uniformity of implementation of the noise certification requirements of Part 36 of the Federal Aviation Regulations (FAR) by presenting technically acceptable test, analysis, and documentation procedures for subsonic turbojet airplanes that may be used by applicants for demonstrating compliance with Part 36. Where appropriate, FAA policy governing such certifications is reviewed.
