U.S. President's executive order directs FAA to abolish over 50 years of civilian land supersonic flight ban

IT Home June 9th news, according to a press release on June 6th local time at the White House, the U.S. President signed an executive order to promote supersonic aviation in the United States on the same day, instructing the director of the Federal Aviation Administration (FAA) to abolish the ban on (civil) land supersonic flights.

Although supersonic aviation can further shorten the time of air travel, the sonic boom that breaks the sound barrier has a practical impact on the lives of ground residents, so civilian supersonic flights on land have always been strictly restricted. The FAA ban was issued 52 years ago in 1973.

In recent years, due to the evolution of aeronautical engineering, materials science and noise reduction technology, the impact of sonic boom noise on the ground can be substantially suppressed. Some companies have restarted the development of supersonic passenger aircraft projects. Several members of the U.S. Congress also proposed a cross-party bill to lift the ban on supersonic flights last month.

According to the Presidential Executive Order, FAA Other regulations that hinder supersonic flight will be abolished and supersonic aircraft noise certification standards will be formulated based on temporary certification standards; the US Office of Science and Technology Policy will lead the coordination of supersonic research, development, testing and evaluation; the FAA and other relevant agencies will participate in the formulation of global supersonic flight rules.

However, supersonic civil aviation is not the only main obstacle to sound barriers. The previous retirement of the Concorde is closely related to fuel economy (high fares) and safety accidents.
