Falcon 6X

The Falcon 6X is largely based on the Falcon 5X aerodynamics and systems, validated during its preliminary flight test program, but it is optimized to take advantage of its 13,000–14,000 lbf (58–62 kN) PW812D engines for a longer cabin and a greater 5,500 nmi (10,200 km) range, 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 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). Its 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), due to heavier engines, fuel system and structural reinforcements. The Falcon 6X will be the first Dassault aircraft with a nitrogen inerting system.

“The Falcon 6X presents a major step forward for large-cabin business jet operators,”continued Trappier.“Its award winning-cabin–the tallest and widest in business aviation–provides levels of spaciousness, comfort, productivity and safety that will set a new benchmark in the long-range segment.”

With a 5,500 nm (10,186 km) range and top speed of Mach .90, the Falcon 6X can connect passengers to major business centers far and wide. It can fly from London to Hong Kong or from Los Angeles to Moscow nonstop. The Falcon 6X can also perform safe approaches as low as t only 109 knots, slower than other business jets. This allows the 6X like the others Falcons —to safely access small airports equipped with ultra-short and hard-to-reach runways.


With over 10,000 military and civil aircraft delivered in more than 90 countries over the last century, Dassault Aviation has built up expertise recognized worldwide in the design, development, sale and support of all types of aircraft, ranging from the Rafale fighter, to the high-end Falcon family of business jets, military drones and space systems. In 2019, Dassault Aviation reported revenues of €7,3 billion. The company has 12,750 employees.
