Advisory of Transportation U.S. Department Circular Federal Aviation Administration Subject: Date: 2/12/86 AC No: : 36-2C Initiated by: AEE- 110 Change:
Measured or Estimated (Uncertificated) Airplane Noise Levels
1. PURPOSE. This circular provides estimates of noise levels or measured noise levels from airplanes not certificated to FAR Part 36.
2. CANCELLATION. Advisory Circular 36-2B, Measured or Estimated (Uncertificated) Airplane Noise Levels, dated September 6, 1984, 1s cancelled.
3. BACKGROUND.
a. Advisory Circular (AC) 36-1D "Noise Levels for U.S. Certificated and Foreign Aircraft, was published 11/4/85, and lists the results of significant noise certification actions. To supplement that tabulation this circular provides estimates or measurements of the noise from airplanes not required to meet FAR Part 36 standards.
b. Progress in the control and abatement of airplane noise has been, and will continue to be made. A summary listing of existing airplane noise levels will provide both private and public exposure to this progress, as well as offering a common noise level reference for potential future reductions.
4. NOISE LEVELS The noise levels were measured or estimated for each airplane as they might occur during type certification tests conducted under FAR Part 36. However, it should be specifically noted that the estimated levels were not derived from actual tests, and the measured noise levels contained in this circular were obtained from tests which were made for purposes other than type certification. Noise levels are also presented on rotary-wing aircraft which have been estimated or measured and processed according to ICAO Annex 16 standards.
b. Many of these noise levels were obtained from data submitted to the Federal Aviation Administration (FAA) by the manufacturers and from the International Civil Aviation Organization. While the FAA has attempted to verify the reasonableness of these numbers by comparison with those from certified aircraft and (in some instances) by independent measurements, the FAA does not warrant these estimates.
Appendix I shows the measured or estimated noise levels for domestic turbojet powered airplanes; Appendix IA shows measured or
estimated levels for foreign turbojet powered airplanes. Appendix II shows the measured or estimated levels for large transport category aircraft. These appendices include tabulations of engine type, thrust or equivalent shaft horsepower and gross weight for various aircraft as well as the measured or estimated Effective Perceived Noise Level in decibels (EPNdB) for each aircraft. Appendix III shows the noise levels for propeller driven small airplanes. This appendix includes a tabulation of the engine type, horsepower and gross weight for the various aircraft along with the measured or estimated A-weighted sound level in decibels (dBA) compared to a FAR Part 36, Appendix F tests. Appendix IV contains the levels of civil supersonic airplanes. Appendix V shows the noise levels for rotary-wing aircraft. This appendix includes a tabulation of the engine type, horsepower or equivalent shaft horsepower, rotor size and aircraft weight along with the measured or estimated EPNL for level flyover at 500 feet altitude, takeoff, and sideline. For all information listed, except for some aircraft in Appendix V, standard sea level, 77°F, 70% relative humidity conditions have been assumed.
d. Charts have been included following each appendix so that the appropriate FAR Part 36 noise level limits for takeoff, sideline, and approach can be calculated for each airplane for comparison purposes. A chart for calculating the ICAO Annex 16 limits for rotary-wing aircraft has been included for Appendix V.
REVISIONS. The airplane noise level listing of this Advisory Circular will be revised and updated periodically.
