The U.S. Federal Aviation Administration (FAA) is proposing to move away from the current blanket ban on supersonic flight over land, a prohibition in place for about 50 years. Instead of restricting faster-than-sound operations by default, the FAA is expected to base new authorization standards on whether an aircraft produces a sonic boom at ground level. Under the concept described by outlets covering the issue, aircraft would be allowed to exceed Mach 1 over populated areas if they meet a ground-impact limit related to sonic boom intensity.
Industry interest highlighted in reporting includes companies developing “boomless” or low-boom technologies, which aim to enable commercial supersonic travel without the loud boom historically associated with overland operations. Both sources note that changing the regulatory framework would be only one part of bringing supersonic service back. They point to other practical and regulatory hurdles that still need to be addressed, including aircraft engine development and certification, how existing airport and local noise rules would apply, and whether there will be sufficient demand on premium routes to make the economics of faster commercial jets workable.
