Speed

Leaders Arrive First.

TIME IS THE MOST PRECIOUS AND FLEETING COMMODITY. Supersonic speed gives you more of it. More time where you want and need to be. While requiring less time to get there. 

TOP SPEED (Mmo) of the AS2 is Mach 1.5. Rapid transatlantic dashes and other long range routes can be accomplished at this speed, which is 67 percent faster than the top cruise speeds of current or anticipated long-range subsonic jets.

LONG-RANGE CRUISE is Mach 1.4. Aerion supersonic routes are calculated at this speed. At Mach 1.4, travelers save three hours across the Atlantic and six hours or more across long Pacific routes.

BOOMLESS CRUISE(sm) flight is feasible at speeds up to Mach 1.2, depending on atmospheric conditions, principally temperature and wind. At these speeds, the shock waves that cause a sonic boom would, essentially, dissipate before reaching the ground. This “Mach cut-off” cruise results from the normal physics of sonic boom propagation. “Mach cut-off” refers to the maximum speed that can be maintained without producing a boom on the ground. Aerion expects to conduct a flight demonstration program post certification to gain regulatory approval for flight at Mach cut-off speeds.

Success in demonstrating Mach cut-off cruise opens the possibility that the U.S. may adopt International Civil Aviation Organization (ICAO) standards, permitting the AS2 to fly at supersonic speeds over the U.S. (where supersonic flight is now prohibited), as well as internationally.

Subsonic cruise speed is faster than the maximum speed of any conventional subsonic jet. The AS2 cruises efficiently just below Mach 1, and achieves maximum range at Mach 0.95, with the possibility to cruise subsonically at speeds up to Mach 0.98.
