Boeing defends 777X aluminum hull as plastic A350 flies
Improved engines and wings on the 777X will make up for a heavier metal fuselage than the largest A350, Boeing Commercial Airplanes Chief Executive Officer Ray Conner told reporters in Paris. The A350-1000 is due to enter service in 2017, while Boeing has said the 777X may debut by decade’s end.
“It won’t be that bad. I think we’re going to be in decent shape,” Conner said of the planes’ weight differential. “We still believe we have operating economics that will be better.”
Boeing decided against replicating the composite-plastic construction of the 787 Dreamliner, whose first delivery was more than three years late, and opted to use those materials on the 777X’s wings. The A350, which also suffered delays, made its first flight on June 14, days before aerospace executives began gathering for their industry’s biggest annual trade event.
Using the existing 777 production system is part of Chicago-based Boeing’s strategy to reduce the cost of airplane development, Conner said.
Conner called the 777’s fuselage “proven” and among the most popular of wide-body planes. Boeing plans to modify the fuselage to make more space in the 777X, he said. The 777X will burn 20 percent less fuel and have a 15 percent operating improvement over the current 777-300ER, which has tallied 538 orders since the A350-1000 was unveiled, Conner said.
