White Paper – Proposed Supersonic Aircraft and Related Noise Issues

01.30.2019 | Mary Ellen Eagan |

A recent resurgence of interest in supersonic air travel has drawn attention to ongoing research and development, and has sparked discussions of the drawbacks, specifically noise concerns. Since Concorde was retired in 2003, there have been no civilian supersonic aircraft in service, and current FAA regulations prohibit flight in excess of Mach 1 (approximately 767 mph) over land. However, the possibility of shortening long-haul (primarily business) flights has fueled competition among aircraft manufacturers to produce viable options. Meanwhile, regulatory agencies and airport operators are considering the implications on environmental noise.

This white paper explores the range of technologies that have been proposed by a number of manufacturers, as well as the noise certification process.
