Boeing has brought together the major fuselage sections to form the first flight test 777X aircraft.
In a major production milestone called ‘final body join,’ Boeing teams connected the nose, mid and aft sections in the company’s factory in Everett, Wash. The jet now measures 252ft (77m) long from nose to tail, making it the longest passenger jet the manufacturer has ever produced.
The 777X builds on the 777 and the 787 Dreamliner to offer airlines what Boeing describes as “the largest and most-efficient twin-engine jet in the world” with 12% lower fuel consumption and 10% lower operating costs than its competitor, the A350.
The 777X features General Electric GE9X turbofans and an all-new composite wing design featuring folding, raked wingtips,
The first 777X introduced will be the 777-9 model, which can seat 400 to 425 passengers in a standard configuration and offer a range of 7,600nm (14,075 km). The 777X first flight is scheduled for 2019 and first delivery for 2020.
