A proposed rule by the US Federal Aviation Administration (FAA) aims to lift the long-standing ban on commercial supersonic flights over the United States, originally enacted in 1973. This change is part of an initiative promoted by the Trump administration to facilitate the introduction of supersonic airliners that minimize disruptive sonic booms. The new regulation, announced on June 30, 2026, would establish an interim noise-based certification standard, which requires any sonic boom overpressure at ground level to remain below 0.11 pounds per square foot. This standard is informed by tests conducted by the Colorado-based startup Boom Supersonic, which demonstrated its XB-1 aircraft’s ability to achieve quieter supersonic flights by utilizing specific atmospheric conditions to direct shockwaves upward rather than downwards.
Why It Matters
The FAA’s proposed rule reflects an evolving regulatory landscape that seeks to balance technological advancements in aviation with public concerns about noise pollution. The original ban on supersonic flights was established after military tests revealed the disruptive impact of sonic booms on populated areas. The new certification standard is a response to ongoing innovations in aircraft design aimed at reducing noise emissions, indicating a shift in how aviation regulations adapt to technological developments. This move could potentially revitalize the commercial aviation market by reintroducing supersonic travel, which has been absent for decades.
