Dassault Falcon 6X: The Wide Cabin

The Falcon 6X is built around its cross section. The cabin is 6 ft 6 in (1.98 m) high and 8 ft 6 in (2.58 m) wide, which Dassault describes as the tallest and widest in business aviation, and it pairs that space with a range of 5,500 nm at Mach 0.80 with eight passengers. It does not compete with the ultra long range jets on distance. It aims at long but not extreme sectors, such as Paris to Los Angeles or London to Hong Kong, in a cabin with more room across than its larger rivals.

The cross section, compared

Width is the dimension you feel most once seated, because it decides the aisle, the seat and the distance to the person opposite. The comparison with the ultra long range jets is instructive: the Gulfstream G700 is quoted at 8 ft 2 in wide and 6 ft 3 in high, the Bombardier Global 8000 at 8 ft 0 in and 6 ft 2 in. The 6X adds several inches in both directions, which designers can spend on broader seats, a wider aisle or a dining table that seats four without anyone turning sideways.

The cabin is 40 ft 4 in (12.30 m) long, excluding flight deck and baggage, and Dassault lists seating for 12 to 16 passengers depending on the layout. A typical plan uses three zones, with an extended entry and galley at the front and a stateroom at the rear, and a crew rest area can be included. Baggage volume is 155 cu ft (4.4 m³).

Light and air

Thirty extra-large windows line the cabin, and there is a skylight above the forward galley, a detail Dassault presented as a first in business aviation. Galleys are often the darkest part of a cabin because cupboards and appliances cover the windows, so daylight from above makes a real difference to the crew and to anyone walking through. Cabin altitude is 3,900 ft at 41,000 ft. For how these choices fit current thinking on cabins, see cabin design now.

Range, speed and runway

Two Pratt & Whitney Canada PW812D engines of 13,500 lb thrust each give a maximum operating Mach number of 0.90 and a ceiling of 51,000 ft. Dassault quotes 5,500 nm at Mach 0.80 with eight passengers, three crew and NBAA IFR reserves, and 5,100 nm at Mach 0.85.

The 6X needs less runway than the ultra long range jets. Takeoff distance at maximum weight, sea level and ISA is 5,115 ft (1,560 m), against 5,760 ft for the Global 8000 and 5,995 ft for the G700. Unfactored landing distance at a typical landing weight is 2,440 ft (744 m), with an approach speed of 110 kt. Commercial operators apply landing factors to that figure, but a modest approach speed is what makes demanding airports workable, and on medium sectors a lighter 6X needs well under its maximum takeoff distance.

Typical missions

• Paris to Los Angeles: about 4,900 nm great circle.
• London to Hong Kong or London to Tokyo: each about 5,200 nm.
• Paris to Beijing: about 4,400 nm.
• New York to Tokyo: about 5,900 nm, beyond the published range and a stop on most days.

Large-cabin jets also fly many shorter trips: a ski weekend, a Gulf business day, a summer week on the Mediterranean. That is where the shorter runway requirement and the wide cabin both pay off, without the cost of an ultra long range jet carrying fuel it does not need. The Aircraft Finder shows how it compares for a given trip.

Who it suits

The 6X suits owners and groups who value cabin space over the last thousand miles of range: families who want room to move on transatlantic trips, companies that use the cabin as a meeting room. Those who regularly fly Asia to the American West Coast nonstop will look at the G700 or the Global 8000 instead. Because it entered service at the end of 2023, the 6X is still a young type in charter fleets and may be harder to find than older large-cabin jets, so ask early and read how to read a spec sheet before comparing quotes for different aircraft.

Questions

How far can the Dassault Falcon 6X fly?

Dassault quotes 5,500 nm at Mach 0.80 with eight passengers, three crew and NBAA IFR reserves, and 5,100 nm at Mach 0.85. That covers routes such as Paris to Los Angeles or London to Hong Kong on paper, subject to winds and payload.

How big is the Falcon 6X cabin?

The cabin is 6 ft 6 in (1.98 m) high, 8 ft 6 in (2.58 m) wide and 40 ft 4 in (12.30 m) long excluding flight deck and baggage. Dassault describes it as the tallest and widest cabin in business aviation.

Does the Falcon 6X have a skylight?

Yes. A skylight sits above the forward galley, an area that is normally dark because cabinets cover the windows. Dassault presented it as a first in business aviation, alongside 30 extra-large cabin windows.

When did the Falcon 6X enter service?

EASA and the FAA certified the Falcon 6X in August 2023, and the first aircraft began flying for its owner at the end of November 2023.
