Executive Order 14304: Leading the World in Supersonic Flight

What does Executive Order 14304 do?

The text directs FAA to propose repeal of categorical prohibition, and FAA to issue noise-based standard and final rule.

Later primary evidence reviewed September 24, 2026: FAA proposed to replace its overland supersonic-flight prohibition with a noise-based standard as this order directed. Official source. The cited steps do not establish every downstream effect.

Reading the operative provisions of Executive Order 14304

EO 14304 directs the Federal Aviation Administration to replace the categorical ban on civil supersonic flight over land with noise-based standards and to consider certification rules for aircraft that meet those standards. It seeks to permit faster aircraft while addressing sonic-boom effects on communities. The Federal Register text of EO 14304 directs FAA rulemaking; it does not immediately authorize commercial supersonic flights over U.S. land.

A sonic boom is produced when an aircraft travels faster than sound, and its intensity at ground level depends on aircraft design, altitude, speed and atmospheric conditions. A noise-based standard would give manufacturers a target to meet and regulators a way to evaluate aircraft. FAA must define a measurable standard, determine how compliance is tested and account for noise exposure across communities. Until the agency adopts an effective rule, existing restrictions continue to govern.

Aircraft certification and operating rules are separate steps. A design might meet a noise limit but still need airworthiness certification, route approval, pilot procedures and other safety reviews. FAA’s rulemaking also requires public notice and a reasoned response to comments. The order’s objective is to remove a categorical barrier if technology can meet an acceptable standard; the actual legal change depends on the rule and the evidence supporting it.
