US looks to speed air taxis, supersonic planes to market
The agency is addressing certification and noise rules as eight pilot partners test eVTOL aircraft in 26 states, officials said.
At the Farnborough International Airshow in England on July 21, Deputy FAA Administrator Chris Rocheleau announced the Federal Aviation Administration is accelerating regulatory approvals for electric vertical takeoff and landing aircraft and civil supersonic aircraft.
A ban written into 14 CFR 91.817 has stopped civil aircraft from exceeding Mach 1 over US land for more than five decades, dating to public opposition in the 1960s when sonic booms broke windows and damaged property in Oklahoma City.
Data from the pilot program with eight partner companies across 26 states over three years will inform certification efforts; Joby recently flew a seven-minute JFK hop, while Archer Aviation CEO Adam Goldstein said the industry has learned from autonomous vehicle deployments.
The FAA proposed allowing aircraft to fly faster than sound over land if sonic boom overpressure stays at or below 0.11 pounds per square foot, using 'Mach cutoff' techniques, as Colorado-based Boom Supersonic completed its XB-1 demonstrator flight earlier this year.
Public comment on proposal docket FAA-2026-6935 closes August 17, 2026, with both rules targeted for finalization by mid-2027, amid intensifying competition between the United States, China, and Europe over aerospace and space technologies.
