Development of Dassault’s ­Falcon 8X ultra-long-range business jet is advancing rapidly as the French airframer prepares to mate the wings to the fuselage of the first test aircraft at its ­Bordeaux, Mérignac facility.

Dassault expects to join the 8X’s three Pratt & Whitney ­Canada PW307D engines soon after, and fly the first of the $57 million flagship aircraft early next year.

The 8X, unveiled in May, is the largest, fastest and longest-range aircraft in the French airframer’s six-strong high-end ­business jet family, whose entry level product is the 3,350nm (6,200km)-range super-midsize 2000S.

The 8X is a stretched, ­refined version of the seven-­year-old 7X tri-jet, which is now ­approaching its 250th delivery milestone. It ­features a redesigned ultra-efficient wing derived from the 7X; a redesigned 13m (42.6ft) cabin – available in 30 configurations with up to 33 windows ­– and more powerful and fuel-efficient powerplants.

Dassault has introduced a number of refinements and enhancements to the aircraft’s ­design, including an extra fuel tank within the centre fuselage section, which enables the 8X to carry up to 15,800kg (34,900lb) of fuel: 1,300kg more than the 7X.

The extra fuel also helps to boost the 8X’s range to 6,500nm – 500nm further than its $52 million stablemate.

Certification and service entry of the 8X are scheduled for mid- and late-2016, respectively.
