A major production milestone on the development of the Boeing 777X flight test aircraft was recently completed. The global aerospace manufacturer has combined the main fuselage sections of the aircraft that is scheduled to launch in 2019.

Completing what is known within the industry as the ‘final body join’, Boeing successfully connected the aeroplane’s nose, mi and aft sections at the company’s factory in Everett, Washington.

"The 777X is a new aeroplane and a new production system," said Josh Binder, vice president and general manager of the 777X.

"With the 777X, the production system was integrated into the development program sooner than any other aeroplane, and the team is doing a great job of hitting our milestones as expected."

Building upon the popular 777 and 787 Dreamliner aircraft, the 777X measures 252 feet long from nose to tail and delivers 12% lower fuel consumptions, along with 10% in lower operating costs than competing aeroplanes.

Boeing’s 777X aircraft achieves this high level of performance thanks to the introduction of the GE9X fuel-efficient commercial engine, as well as an all-new composite wing design that delivers improved lift and efficiency.

A distinct trait of the designs is the extension of a set of folding, rake wingtips, which extends the aircraft wingspan to 235 feet.

The first variant, which will be the 777-9 model, is expected to hold 400 to 425 passengers in a standard configuration and boasts a range of 7,600 nautical miles.

Following the successful completion of the first flight in 2019, the delivery of the first 777X aircraft is scheduled for 2020.
