The aircraft manufacturer claims the long-range model, which is due to enter service in 2022, will have the widest cabin available on the market.

On December 8, 2020, the ultra widebody Falcon 6X made its debut in Dassault’s Charles Lindbergh Hall in Bordeaux-Merignac. It was streamed online for a global audience and hosted by noted TV journalist, Miles O’Brien. The show featured Eric Trappier, Chairman & CEO, Dassault Aviation, Carlos Brana, Senior Executive VP, Civil Aircraft, and others; with interviews, videos and, of course, the star of the show, the 6X.
The company is ready to start flight testing early in 2021 as it aims to get the aircraft into service by the end of 2022. It says the 6X has the widest cabin yet and will offer impressive performance, comfort, and safety.
Latest Technology
The Digital Flight Control System (DFCS) commands all flight control surfaces, automatically ensuring peak performance and efficiency at all times. Its auto-trim function eliminates the need for constant pilot input. And flight envelope protection avoids exceeding structural speed limits and stalls. Hazard avoidance is enhanced and go-arounds are easier and safer. Flying a Falcon with DFCS imposes a far lower workload on the pilot more than any other aircraft.
The Falcon 6X will be the first Dassault aircraft with a nitrogen inerting system.
Engines
The Pratt & Whitney PW812D engine sets new standards in aircraft performance, fuel efficiency and sustainability. Its low-noise design shares the same proven technology as Pratt & Whitney’s award-winning commercial engines. And its advanced design makes it easier to maintain, so there’s less aircraft downtime.
The new engine fans will have a diameter of 112–15 cm (44–6 in) narrower than in the Gulfstreams, and with four low-pressure turbine stages instead of five. Engine weight is reduced by 91 kg (200 lb).
General Specs
The Falcon 6X is largely based on the Falcon 5X aerodynamics and systems,
A Mach 0.90 top speed and a Mach 0.85 cruise. Its cabin is 12.3 m (40 ft.) long, is 1.98 m (78 in) high by 2.58 m (102 in) wide (the largest in a purpose-built business jet), and can accommodate 16 passengers in three zones with 29 windows, including a galley skylight.
A front-fuselage extension makes its cabin 51 cm (20 in) longer.
The Falcon 6X reinforces the 5X new 70.7 m2 (761 sq. ft.) wing and keeps its digital flight control system and Honeywell Primus Epic EASy III flight deck.
The 6X empty weight increases by 1,030 kg (2,270 lb) or 5.7%, from 18.1 to 19.2 t (40,000 to 42,300 lb).
