Dassault Falcon 10X Completes Maiden Flight in France

Dassault Aviation officially launched the flight test campaign for its new flagship ultra-long-range business jet on June 19, 2026, as the Falcon 10X completed a two-hour and 30-minute maiden flight from Bordeaux-Mérignac Airport (LFBD) in France.

The inaugural flight transitions the Falcon 10X program from development into active certification testing, targeting entry into service in 2027. According to a press release issued by Dassault Aviation, the aircraft reached an altitude of 40,000 feet and a speed of Mach 0.82 during the initial evaluation.

Flight profile and test program structure

Taking off at 11:10 a.m. local time, the aircraft was crewed by Dassault Aviation test pilot Sébastien Dupont de Dinechin and copilot Fabrice Dougnac. The crew conducted an initial systems evaluation at 15,000 feet before climbing to the flight’s maximum altitude of 40,000 feet. The aircraft landed back at Bordeaux-Mérignac at 1:40 p.m. local time.

Following the flight, Dupont de Dinechin stated the milestone was the culmination of years of work by thousands of Dassault employees and partners.

“It paid off in a flight that went as planned and was a delight to fly,” Dupont de Dinechin said.

Dassault Aviation will utilize three aircraft for the flight test program. The first prototype is dedicated to flight envelope expansion. A second test aircraft is currently nearing completion and will be used for systems and performance validation. A third aircraft will be outfitted with a full interior to conduct cabin functional and reliability testing.

Performance specifications and engine integration

The Falcon 10X is positioned to compete in the ultra-long-range, large-cabin business jet market. Official Dassault specifications list a maximum range of 7,500 nautical miles and a top speed capability of Mach 0.925. The aircraft also features the manufacturer’s new NeXus flight deck.

Powering the aircraft are two Rolls-Royce Pearl 10X engines. In a separate statement, Rolls-Royce confirmed the engines successfully powered the maiden flight, marking the start of rigorous airframe and engine testing to deliver key data for final certification. Each Pearl 10X engine produces more than 18,000 pounds of thrust.

Dassault Aviation Chairman and CEO Eric Trappier highlighted the collaborative effort behind the milestone, describing the flight as a reflection of the dedication of the engineering, production, and flight teams, as well as the quality of the company’s global network of partners.

Program timeline and market positioning

Dassault Aviation officially launched the Falcon 10X program on May 6, 2021. The first prototype was rolled out to the public on March 10, 2026, at an event in Mérignac attended by over 400 customers, partners, and aviation executives.

According to reporting by Aviation International News, Dassault is targeting type certification and entry into service for the Falcon 10X in 2027.

AirPro News analysis

The successful maiden flight of the Falcon 10X keeps Dassault on a competitive timeline in the lucrative ultra-long-range business jet segment. By utilizing three dedicated test aircraft, the manufacturer is structuring a parallel testing campaign designed to compress the timeline between first flight and final certification. We expect the integration of the Rolls-Royce Pearl 10X engines and the new NeXus flight deck to be primary focus areas during the initial flight envelope expansion phase over the coming months.
