A second Falcon 10X prototype has been involved in flight testing since making its first flight from Dassault Aviation’s Mérignac site near Bordeaux on September 24. The company confirmed that the aircraft (S/N 2) has joined the first prototype of the long-range business jet, which is flying three sorties per week from Istres in southern France. Each flight lasts around four hours to expand the flight envelope with higher speeds, angles of attack, and altitudes, Dassault told AIN.

The inaugural 10X prototype made its first flight on June 19. A month later, Dassault announced that the service entry target date for the new Falcon slipped by two years to 2029, with chairman and CEO Éric Trappier explaining that additional time is needed due to the more stringent regulatory environment after the Boeing Max debacle.
