It is larger than any Airbus not custom converted from air cargo or bulk passenger configurations is the point. This represents an example of essentially a new class of aircraft. One of the ways you can see that is militaries are directly buying these aircraft instead of trying to build similar aircraft custom designed to be military aircraft as they simply cannot compete against the capabilities of modern large business jets pushing this envelope.

The Falcon 10X’s cabin width stands at 2.77 m (9.1 ft.) and its height at 2.03 m, making it the widest and tallest cabin in purpose-designed bizjets. The increased width allows a passenger to leave the table in a conference area without disturbing other passengers, Philippe Reignier, technical sales manager, told reporters. The aft bedroom accommodates a 60-in.-wide bed.

The four-zone, 78.7-m3 cabin is highly modular, meaning customers can have partition walls installed virtually anywhere. “We describe an area as a three- or six-window lounge, for instance,” Reignier said.

Systems such as electric wiring and emergency oxygen ducts offer enough interfaces in the cabin for each zone to have sufficient outlets, whatever the zone’s length. Layouts in previous bizjet designs made it difficult to install a partition outside the planned location, a Dassault engineer explained. The small intervals between the structure’s frames and the large number of windows—38, each with a 30% greater surface area than on the recent Falcon 6X—contribute to the improved flexibility in the cabin’s floor plan.

Ultra-long-range jets like the Falcon 10X typically command charter rates in the range of $10,000 to $15,000+ per hour, depending on region, fuel prices, crew fees, and operator specifics, and Jettly explains how private jet charter costs are calculated in more detail.

A Falcon 10X-class jet is ideal for:

Nonstop trips exceeding 5,000–6,000 nautical miles

Groups of 10–16 passengers requiring distinct rest and work zones

Time-critical business travel demands flexibility and speed

Multi-continent itineraries without intermediate stops

For shorter flights under four hours, regional meetings, or smaller groups of 4–6 travelers, smaller jets may offer better value, and Jettly’s guide to affordable, budget-friendly aircraft choices can help identify suitable options.

Not only are you missing that this aircraft is aimed at a part of the aircraft market that has not been addressed with a configurable highly advanced large jet business aircraft that can be easily set up for extremely advanced military or civilian roles, the airframe itself was constructed with very advanced techniques that are notable themselves. Primarily, the Falcon 10x is the first all composite-wing business jet and the body has a significant amount of composite shaping to it that goes beyond the traditional metal tube and wing design limitations that metal airframes are more limited by.

These aircraft represent such a unique capability that while these jets are designed for commercial purposes they out perform similar military aircraft by such a large margin that they are becoming the bread and butter of electronics warfare, surveillance and signals intelligence done at a regional scale by nationstates (along with orbital assets). The impacts aren't just for military and dystopian surveillance uses though, these jets could just as also be turned into mobile extremely advanced scientific sensors set up to gather very high resolution climate data in real time for example.

The composite body shaping is important because the "tube and wing" airplane design is aerodynamically extremely inefficient. Wing-in-body aircraft will take over, the limitation is industrial-scale sophisticated and economical composites shaping becoming a practical reality for aircraft manufacturing, which this aircraft is also a bellwether for.

Mission analysis is performed for the blended wing body, a conventional tube-and wing variant with metallic structures, and an advanced tube-and-wing with composite structures. The results show that the blended wing body operates with 15-20% higher lift-over-drag during the cruise, 24% lower fuel burn for the design mission, and 15% reduction in ramp weight relative to the conventional tube-and-wing. These differences drop to 20% for the design mission fuel burn and 10% for the ramp weight relative to the advanced tube-and-wing. When the engines are re-sized and optimised separately for each configuration, the blended wing body demonstrates a 25% improvement in block fuel and 16% reduction in ramp weight relative to the conventional tube-and wing, which decreases to 21% and 10% relative to the advanced tube-and-wing.

Casual observers might imagine the Dassault Falcon 10X is turning its nose up at the other jets around. Though some might say it has good reason to do so, its distinctive nose serves a far more practical purpose while also hinting at the jet’s clean sheet design.

That clean sheet approach was necessary to allow Dassault to build an ultra-long-range jet capable of covering its full 7,500nm range as quickly and efficiently as possible – in this case Mach 0.85 (maximum cruise at shorter range is Mach 0.925) – while also offering the largest cabin on the market.

A significant part of Dassault succeeding in its objective is tied in with the Falcon 10X’s aerodynamics.

That unique nose-shape, for example, combined with a flatter fuselage directly above the cockpit ultimately allow for greater airflow efficiency, reducing the effects of headwinds and helping to optimize high-Mach cruise. Meanwhile, the flatter roof also serves to reduce noise in the cockpit.

Moving along the exterior, the wing to fuselage fairing is another area Dassault carefully addressed, developing and refining the design to minimize vortex generation and drag and promote the cruise speed/range objectives.

The wings themselves – including the panels, spars and ribs – are advanced carbon fiber composite, helping lessen weight while affording greater flexibility to dampen turbulence and enhance passenger comfort.
