The U.S. Federal Aviation Administration (FAA) has issued new final rules to help pave the way for the re-introduction of supersonic commercial flight. The U.S. airspace regulator’s rules provide guidance for companies looking to gain approval for flight testing of supersonic aircraft under development, which includes startups like Boom Supersonic, which has just completed its sub-scale supersonic demonstrator aircraft and hopes to begin flight testing it this year.
Boom, which is in the process of finalizing a $50 million funding round and has raised around $150 million across prior fundraising efforts, rolled out its XB-1 supersonic demonstrator jet in October. This test aircraft is smaller than the final design of its Overture passenger supersonic commercial airliner, but will be used to prove out the fundamental technologies in flight that will then be used to construct Overture, which the company is targeting for a 2025 rollout with airline partners.
Other startups, including Hermeus, are also pursuing supersonic flight for commercial use. Meanwhile, SpaceX and others focused on spaceflight like Virgin Galactic are exploring not only supersonic flight, but how point-to-point flight that includes part of the trip at the outer edge of Earth’s atmosphere might reduce flight times dramatically and turn long-haul flights into much shorter, almost regional trips.
The FAA’s rules finalization comes in under the wire as the agency prepares for a transition when current U.S. Transportation Secretary Elaine Chao moves aside for incoming Biden pick Pete Buttigieg. You can read the full FAA final rule in the embed below.
