And the company has incorporated the folding, 11-foot-long tips on each wing-and managed the added weight and complexity that comes with such a feature-just to ensure the new airplane can fit at a standard airport gate. With the 777x, Boeing is going to all the trouble to create such a long wing for one simple reason: it allows the plane to be more efficient as it flies. That’s wider than the wings on existing Boeing 777s or the 787, and about double the wingspan of a 737.
In both models of the new aircraft-the 777-8 and the 777-9-the wings will measure 235 feet from tip to folding tip. But while the size of the plane’s fuselage is what allows it to carry so many people, it’s the design of the wings that really sets it apart from an engineering perspective. When the new widebody 777x enters service, it will seat as many as 426 people in its longest of two configurations. On Saturday, Boeing flew its newest passenger plane for the first time, and after it landed in Seattle, its wingtips did something new to the world of commercial aviation: they folded upwards as the plane was still rolling down the tarmac.
