While Dassault continues to be tight-lipped about the timing of the first flight for its in-development Falcon 10X, the ultra-long-range business jet’s engines are closer to being ready for service entry. Announcing strong first-half financial results late last week, Rolls-Royce confirmed it has completed all major engine certification tests and has filed reports with regulators for approval.

During Dassault’s financial results press conference on July 22, the French group’s CEO, Éric Trappier, steadfastly blocked reporters’ questions about the timing of the 10X’s first flight. The new Falcon flagship is expected to complete type certification and enter service in 2027. Now, the first prototype is in the advanced stages of assembly at the company’s Bordeaux-Mérignac factory.
