The 777X boasts new General Electric engines and Boeing’s largest-ever wing that comes with a fold to conserve airport space. The plane is hoped to enter service by decade’s end as the first twin-engine jet to haul a jumbo’s payload, while burning 12 percent less fuel than the competing Airbus A350-1000 and 20 percent less than Boeing’s 777-300ER, said Bob Feldmann, a Boeing vice-president and 777X program manager.
The new plane will also stretch the 777’s decades-old aluminum frame and update its pneumatic systems in lieu of the 787’s composite fuselage and all-electric architecture.
