See Inside Boeing’s First-Ever 777X Aircraft; Folding Wingtips


Boeing will initially build the 777X as the 777-9, which will be the world’s largest twin-engine jet, with plans to build the smaller 777-8 variant in the future.

The 777-9 is also the longest commercial airliner ever built at 251 feet and nine inches, beating out the Boeing 747-8, which is just two and a half feet shorter at 250 ft and two inches. The 777-8 will be shorter at 229 feet.

The flagship 777X takes the success of the 777’s large airframe and long-range capabilities and builds upon that with improved efficiency and lower operating costs.

Insider went onboard the manufacturer’s first-ever 777X test plane, known as Flight Test 1, at the Farnborough International Air Show in England to learn more about the program — take a look.

The plane is powered by two large GE9X engines made by General Electric. A Boeing 737’s fuselage could fit inside one of the 777X’s engines.

The engines power the plane’s 13,500-kilometer range (8,388 miles) and offer 10% lower fuel costs compared to the 777-300ER, according to Boeing.

Engineering captain Edwin Navarro told Insider the tanks help control the 777X’s center of gravity (CG), which is necessary for analyzing the stability of the aircraft.

He explained that engineers shift water between the tanks via pipes to change the plane’s CG. Because some tests need a specific CG, the barrels are important for testing very niche conditions.

Behind the tanks are several rows of seats arranged as they would be in an economy class. These are for ferrying Boeing staff between test flights.

The seats give a preview of what a completed 777X interior could look like. The plane is built for ten-abreast seats in economy, which would accommodate up to 426 passengers in a two-class configuration — 30 more than the 777-300ER.

The dense layout is common on the current 777, but the 777X will offer more room so passengers can travel more comfortably.

The configuration competes with the rival Airbus A350. Historically, mainline carriers have only configured the plane with nine seats abreast, minus a few budget airlines like French Bee that have squeezed in ten.
