Dassault Falcon 6X Review: The Widest Cabin, With a Skylight (2026)

The Dassault Falcon 6X was designed around one idea: space where you feel it. Its cabin is 102 in (2.58 m) wide and 78 in (1.98 m) tall, the widest of any purpose-built business jet, and it has 30 large windows plus a skylight. It flies 5,500 nm and borrows control ideas from Dassault’s Rafale fighter. In this review we look at it the way we review airliners: the looks, the cabin, the engines, the cockpit, range, price, safety and how it compares with its rivals.

Quick answer: the Falcon 6X is a large-cabin twinjet that entered service in November 2023. It seats 12 to 16, costs about US$54 million equipped (2023) and flies 5,500 nm, enough for Los Angeles to Geneva or Paris to Johannesburg. Rivals such as the Gulfstream G600 and Bombardier Global 6500 fly further, but none has a cabin this wide or tall.

What Is the Falcon 6X?

The Falcon 6X sits between the Falcon 2000LXS and the three-engine Falcon 8X in Dassault’s range (see our guide to every Dassault Falcon). Its story starts with another jet. Wikipedia says Dassault launched the Falcon 5X in 2013 with new Safran Silvercrest engines, but the engines did not meet their performance goals. On 13 December 2017, Dassault cancelled the 5X and replaced it with a new design that kept the same wide fuselage cross-section but used Pratt & Whitney Canada engines.

That design, the Falcon 6X, was unveiled in February 2018. A 20 in (51 cm) extension at the front made its cabin longer than the 5X’s. The first aircraft was rolled out on 8 December 2020 and first flew on 10 March 2021. The FAA and EASA certified it in August 2023, and it entered service on 30 November 2023. Government users include the Irish Air Corps and the Government of Serbia, which each received one in 2025.

How the Falcon 6X Looks: Exterior Design

The 6X is 84.3 ft (25.68 m) long with an 85.1 ft (25.94 m) wingspan, noticeably shorter than the ultra-long-range Globals and Gulfstreams. Its fuselage looks fat for its length, because of the wide cabin inside. It has two engines at the back, a Falcon-style tail with the horizontal tail set partway up the fin, and a long row of windows.

A wing with fighter ideas

The wing has flaperons, control surfaces that work as both ailerons and flaps. Dassault says they were borrowed from the Rafale fighter and add roll control and drag on approach, so the jet can fly slower and steeper when landing. Its approach speed is just 110 kt, which Dassault says is up to 10 kt slower than most jets with similar range, and it can use steep-approach airports such as London City and Lugano.

How to recognise a Falcon 6X at the airport

• Two engines at the back (the Falcon 8X and 900LX have three)
• A wide, rounded fuselage with a long row of windows
• The horizontal tail sits partway up the fin, not on top of it
• Look for “6X” on the tail on Dassault’s own aircraft

The PW812D Engine, Explained Simply

Two Pratt & Whitney Canada PW812D turbofans each give 13,500 lb (60.00 kN) of thrust. They belong to the PW800 family; Transport Canada certified the PW812 in November 2021, according to Wikipedia. Each engine has a 44 in (110 cm) fan and weighs about 200 lb less than the PW800 versions used on Gulfstreams. Dassault highlights the TALON X combustor, which cuts emissions, a low-noise design and compatibility with sustainable aviation fuel.

These are smaller engines than the 18,000-plus lb units on the Global 8000 and G700, which fits a jet built for 5,500 nm rather than 8,000. Learn how turbofans work in our turbofan vs turboprop guide.

Inside the Cabin: Width, Height and Light

The cabin is the Falcon 6X’s headline. It is 40.3 ft (12.30 m) long, 102 in (2.58 m) wide and 78 in (1.98 m) tall, with 1,843 cu ft of space. Wikipedia calls it the widest purpose-built business jet cabin. At 6 ft 6 in, it is tall enough for almost everyone to walk upright, and the extra width lets designers fit wider seats and a proper aisle between them. Wikipedia describes a 16-seat layout in three zones.

1. Thirty windows and a skylight

Dassault lists 30 extra-large windows plus a skylight. The skylight, which Wikipedia places in the galley, brings daylight into the area where the crew prepares meals. Mood lighting, which passengers control, is designed to help manage your body clock across time zones.

2. Clean, fresh air

Dassault says the cabin air is refreshed up to ten times faster than in a modern office building and is ten times better than minimum requirements, with hospital-grade HEPA/ULPA filters that capture 99.97% of particles. Dassault does not quote a cabin altitude on the 6X page.

3. A quiet cabin

Dassault says the 6X is among the quietest cabins in the industry, using soundproofing technology developed for other Falcons.

4. Privacy Suite and connectivity

An optional Privacy Suite has an adjustable divider and berthable seats, so it can be a meeting room by day and a bedroom at night. FalconConnect broadband lets passengers use their own devices for entertainment and to control the cabin.

The Cockpit: EASy IV and FalconEye

Pilots fly the 6X from Dassault’s EASy IV flight deck, built on Honeywell’s Primus Epic system. It has a digital flight control system with envelope protection, which stops pilots from pushing the aircraft beyond safe limits, integrated with nosewheel steering. Dassault also builds the Rafale fighter, and the 6X uses the same kind of digital flight controls.

The standout is FalconEye, a combined vision system that blends infrared and synthetic images on the head-up display. Dassault says it gives pilots guidance on approaches down to 100 ft before the runway is visible. There is also an audible alert to help prevent runway overruns, the FalconSphere electronic flight bag, and FalconScan, a health-monitoring system that spots maintenance problems early.

Range and Performance

Dassault quotes 5,500 nm (10,186 km) with 8 passengers and NBAA IFR reserves, or up to 5,100 nm at Mach 0.85. Its named nonstop examples are Los Angeles to Geneva, São Paulo to London and Paris to Johannesburg. Dassault also gives an example of a short hop from Chicago Executive to New York, followed by a Mach 0.85 flight to London City.

One clever feature: after a short flight, the 6X can land at 85% of its maximum take-off weight, Dassault says, and still fly almost nine hours to an overseas destination without refuelling. That suits owners who pick up passengers in one city before crossing an ocean.

Safety and Reliability

Wikipedia lists no accidents or incidents involving the Falcon 6X. It is certified by the FAA and EASA, and it is the first Dassault aircraft with a nitrogen inerting system, which fills the empty space in the fuel tanks with nitrogen-rich air to reduce the risk of a fuel tank fire. Envelope protection, FalconEye and the runway overrun alert add further layers of safety. Dassault’s FalconResponse service can send a replacement aircraft if a 6X is grounded away from base.

Price and Who Flies It

Wikipedia lists an equipped price of about US$54 million (2023), far below the ultra-long-range flagships, which cost US$72 million to US$81 million. Wikipedia names the Irish Air Corps and the Government of Serbia as government operators, and says the first US private (Part 91) delivery took place in late 2024.

Falcon 6X vs Its Rivals

Sources: Dassault Falcon: Falcon 6X, Gulfstream: G600, Bombardier: Global 6500.

Falcon 6X vs Gulfstream G600

The G600 flies 1,100 nm further and has a longer cabin, but the 6X is 11 in wider. If you fly mostly transatlantic or Europe to the Middle East, the 6X’s range is enough and the extra width is noticeable. See our Gulfstream guide. Full head-to-head: Falcon 6X vs G600.

Falcon 6X vs Bombardier Global 6500

The Global 6500 also flies 6,600 nm and seats up to 17. The 6X wins on width and height; the Global wins on range. See our Bombardier guide.

Falcon 6X vs Falcon 8X

Dassault’s own three-engine Falcon 8X flies further (6,450 nm) and has a longer cabin, but the 6X has the wider, taller cross-section (102 in against 92 in wide). Choose the 8X for range, the 6X for cabin comfort.

Pros and Cons

Pros

• Widest purpose-built business jet cabin: 102 in
• 78 in of headroom: almost everyone can stand
• 30 large windows plus a unique skylight
• Slow 110 kt approach; London City and Lugano capable
• FalconEye and digital flight controls with envelope protection
• Much cheaper than the ultra-long-range flagships

Cons

• 5,500 nm range is less than the G600 and Global 6500 (6,600 nm)
• Shorter cabin (40.3 ft) than its main rivals
• Seats up to 16, against 17 to 19 in rivals
• Dassault does not publish a cabin altitude for the 6X

Our Verdict

The Falcon 6X is the most comfortable large-cabin jet for missions up to about 5,500 nm. Its width and height make the cabin feel like a room rather than a tube, the skylight and 30 windows fill it with light, and its fighter-derived flight controls and slow approach speed let it use airports that bigger jets cannot. It does not fly as far as a G600 or Global 6500, so if you regularly cross the Pacific, look elsewhere. For transatlantic, Europe to Asia or Middle East trips, it is one of the best private jets you can buy.

Key Takeaways

• The Falcon 6X has the widest (102 in) and one of the tallest (78 in) business jet cabins, with a skylight.
• It flies 5,500 nm with 8 passengers and entered service in November 2023.
• It replaced the cancelled Falcon 5X, using Pratt & Whitney Canada PW812D engines.
• It costs about US$54 million equipped (2023), well below the ultra-long-range flagships.
