Abstract:

This report documents work done to support the FAA’s development of Unmanned Aerial Systems (UAS) noise certification and noise measurement criteria. The report discusses the applicability of the Code of Federal Regulation Title 14, Part 36, Appendix J, section J36.205(b) for UAS noise certification. The duration correction in the Appendix J noise certification standard was developed based on observations of aircraft operations in the 1980s. A noise measurement program conducted on a small UAS vehicle at Stow Massachusetts showed that this vehicle’s noise characteristics are not well modeled by the Appendix j duration correction. The report concludes that the Appendix J duration correction should not be used to extrapolate noise measurements at closer distances to the Appendix J fly-over height.
