This is the final stretch for Boeing and its 777X, the world's largest jet that will succeed its best seller, the 777. The American aircraft manufacturer, which began the production of this giant sky in October 2017, indeed touches the goal.

"The main sections of fuselage were assembled, giving birth to the first flight test of this new aircraft whose first takeoff is scheduled for 2019," he said Tuesday night.

During this major phase, dubbed the "final fuselage junction," the teams at the Everett plant in Washington State assembled the front, center, and rear sections of the aircraft, which now measure 77 meters from nose to nose. tail, making it the longest passenger aircraft ever built by Boeing.

But not only. "The 777X is a new aircraft and a new production system. With it, the production system was integrated into the development program earlier than any other aircraft, "said Josh Binder, vice president and general manager of 777X.

The largest jet available

The first member of this long-haul family, the 777X-9 capitalizes on the success of the "Triple 7" and the 787 Dreamliner. Capable of accommodating from 400 to 425 passengers in standard configuration with a range of 14,075 km, "the largest jet available on the market" promises to be a tough competitor for the Airbus A350 and A380 .

Boeing promises that it will consume 12% less fuel than the competition and that its operating costs will be 10% lower. How? Thanks to the GE9X engines provided by General Electric and a brand new fourth generation composite wing. With their folding ends, the wings of the 777X extend over nearly 72 meters, "which improves the aerodynamic efficiency of the wing, reducing engine thrust and fuel consumption."

The first test flight of the 777X-9 is scheduled for March 2019, for a first delivery to its launch company, Emirates, in 2020. Boeing has already registered 340 orders and purchase commitments for its newestborn . In addition to Emirates, which has ordered 150 copies, All Nippon Airways, Cathay Pacific, Etihad Airways, Qatar Airways, Lufthansa and Singapore Airlines are among its customers.
