Dassault Unveils Falcon 5X

Having 5,200 nm of range at 0.80 Mach, the Falcon 5X will be able to fly eight passengers from London to Tokyo, Beijing to Minneapolis or New York to Tel Aviv in 11 hr. 30 min. At 0.85 Mach, it will be able to fly from London to Houston, Detroit to Moscow or São Paulo to Lisbon in under 10 hr.

Glance please at the accompanying specifications box. The Falcon 5X will have a favorable power-to-weight ratio and relatively low wing loading for a large-cabin aircraft with slats. It should offer virtually the best takeoff field length performance of any aircraft capable of flying 5,200 nm.

Dassault is striving to make the 5X its most reliable and most maintainable business jet yet. It will be fully MSG-3-compliant and scheduled maintenance will come at 800-hr. or 12-month intervals. Custom-tailored maintenance programs will be offered to operators.

Extensive high-stress, high-cycle testing of components and systems should minimize growing pains associated with early serial number airplanes. Dassault also is developing a new onboard maintenance monitoring system that will watch up to 10,000 parameters, not unlike the orange flight test boxes bolted into the aircraft for development work. Aircraft health signs and symptoms will be broadcast back to Dassault in real time for analysis. Warranty coverage will be more extensive than with previous Falcon Jets.

Performance and efficiency numbers notwithstanding, the Falcon 5X's trump card is cabin size. No other purpose-built business jet priced less than $55 million equals it.

The Falcon 5X is the most technically advanced civil jet from Dassault, but all of its new systems have been wrung out on other aircraft. Almost nothing on the aircraft is “bleeding edge” technology that might risk the aircraft's spending excessive time in the hangar. Wild frequency AC electrical systems have been used on business aircraft for more than 15 years. The Falcon 7X pioneered the use of digital flight controls on board a purpose-built business aircraft six years ago. The hydraulic system is a basic dual-redundant design with two extra subsystems to provide triple-redundant hydraulic power for the flight control actuators.

Most notably, the Falcon 5X provides a clean-sheet foundation for larger and longer range Falcon Jets, ones that will compete directly against the newest de–signs being developed by Bombardier and Gulfstream. As such, the Falcon 5X isn't just the latest business aircraft to be announced by Dassault, it's also a milestone in the history of the company. It also marks the end of the trijet era at Dassault and the beginning of a whole new line of twin-engine large-cabin aircraft from the French firm that will be more comfortable, more capable and more cost-effective to operate. Construction of the first flight test aircraft is well underway. First flight is slated for the first half of 2015.
