This legislation directs the Federal Aviation Administration (FAA) to issue or revise regulations within one year of its enactment. The purpose of these regulatory changes is to allow for the operation of civil aircraft at supersonic speeds , specifically at a Mach number greater than 1, within the national airspace system. Under these new rules, such supersonic flights would not require special authorization. However, a critical condition for this allowance is that the aircraft must be operated in a manner that prevents any sonic boom from reaching the ground within the United States, aiming to balance aviation modernization with environmental considerations.
