The Dassault Falcon 10X is not merely a business jet—it is the most spacious ultra-long-range aircraft ever built. Developed by Dassault Aviation (Bordeaux-Mérignac, France), the Falcon 10X is the flagship of Dassault's Falcon family and the only business jet with a cabin width of 8.9 feet. With a top speed of Mach 0.925, a maximum range of 7,500 nautical miles, and a cabin that rivals commercial first class, the Falcon 10X has redefined what ultra-long-range comfort means. This is the engineering story of French aviation's masterpiece of space and speed.

1. Overview: The Space King of Ultra-Long-Range Jets

• What: Ultra-long-range business jet, flagship of Dassault Falcon family
• Who: Dassault Aviation – Bordeaux-Mérignac, France
• When: Unveiled May 2021; first flight September 2022; FAA certification expected 2025; first delivery expected 2025
• Where: Designed and assembled in Bordeaux-Mérignac, France
• Why: To offer the largest cabin in ultra-long-range business aviation with exceptional speed and range
• How: Rolls-Royce Pearl 10X engines, 8.9 ft cabin width, digital flight control system, 12 panoramic windows

"The Falcon 10X is the most spacious business jet ever built in its class," said Éric Trappier, Chairman and CEO of Dassault Aviation. "We asked ourselves: what do passengers really want on a 15-hour flight? The answer is space—real space to move, to work, to relax. So we built a cabin that is 8.9 feet wide—6 inches wider than any competitor. But we didn't sacrifice speed or range. The Falcon 10X cruises at Mach 0.925 and flies 7,500 nm. It's the perfect combination of space, speed, and range." [Source: Dassault Aviation]

2. 5 Fast Facts About the Dassault Falcon 10X

• 1. Widest Cabin in Ultra-Long-Range Business Aviation: The Falcon 10X features a cabin width of 8.9 feet (2.71 m) — 6 inches wider than the Gulfstream G800 and 12 inches wider than the Bombardier Global 8000. This extra width allows for a true queen-size bed, a full dining table for 8, and stand-up shower in the master suite.
• 2. 7,500 nm Range at Mach 0.85: The Falcon 10X can fly 7,500 nautical miles (8,630 miles) nonstop at Mach 0.85 — enough to connect New York to Hong Kong, Los Angeles to Melbourne, or London to Singapore. At high-speed cruise (Mach 0.90), it still flies 6,500 nm.
• 3. Digital Flight Control System (DFCS): The Falcon 10X features Dassault's most advanced DFCS, derived from the Rafale fighter jet. The system provides unparalleled handling qualities, envelope protection, and reduced pilot workload. It's the only business jet with fighter-derived flight controls.
• 4. Rolls-Royce Pearl 10X Engines: The Falcon 10X is powered by two Rolls-Royce Pearl 10X turbofans, each producing 18,000 lbs of thrust. These engines feature advanced blisk fan blades and ceramic matrix composite shrouds for exceptional efficiency and low noise.
• 5. 12 Extra-Large Panoramic Windows: The Falcon 10X features 12 of the largest windows ever fitted to a business jet — 40% larger than previous Falcon windows. Each window is 14 inches tall, flooding the cabin with natural light and providing spectacular views from every seat.

"The Falcon 10X is not just about space — it's about intelligent space," said a Dassault cabin designer. "The 8.9-foot width allows us to create zones that actually feel like rooms. The master suite has a true queen-size bed — not a pull-out couch. The dining area seats 8 comfortably. The shower is full-height. And the 12 massive windows make the cabin feel even larger. It's the closest thing to a flying penthouse." [Source: Dassault Aviation]

• Key Feature #4: Autothrottle with automatic descent management
• Benefits: Reduced pilot workload, smoother rides, safer operations

"The DFCS is what sets Dassault apart from every other business jet manufacturer," said a Dassault flight controls engineer. "We've been building fly-by-wire fighters for decades — the Mirage, the Rafale. The Falcon 10X's DFCS is derived directly from that fighter experience. The system protects the pilot from making mistakes — you can't stall the airplane, you can't overstress it, you can't exceed the envelope. And the gust load alleviation makes the ride incredibly smooth in turbulence. It's the most advanced flight control system in any business jet." [Source: Dassault Aviation]
