Dassault Aviation has pushed the expected entry into service of its Falcon 10X from 2027 to 2029, extending the development timeline for what will become the company’s largest and longest-range business jet. Dassault CEO Eric Trappier attributed the delay largely to increasingly demanding certification requirements for clean-sheet aircraft designs.

The revised schedule comes shortly after the Falcon 10X completed its maiden flight on 19 June 2026 from Bordeaux-Mérignac. The first test aircraft flew for two and a half hours, reaching 40,000 feet and Mach 0.82, officially launching the programme’s flight-test campaign. Two additional flight-test aircraft are expected to join the certification effort.

With a planned range of 7,500 nautical miles, a maximum operating speed of Mach 0.925 and a cabin more than nine feet wide, the 10X is being positioned directly against the largest ultra-long-range aircraft from Gulfstream and Bombardier.

For customers, however, the two-year shift means longer waits for one of the most anticipated aircraft in business aviation. It could also support demand and residual values for existing large-cabin Falcons and competing preowned aircraft while Dassault works through certification.

The delay highlights a wider challenge facing manufacturers developing entirely new aircraft. As certification standards become more complex, programmes increasingly require greater testing, validation and engineering resources before reaching customers.

For Dassault, the priority is now clear: complete the 10X flight-test programme and bring its new flagship to market without compromising certification or maturity.
