Boeing 777-9X Will Be the World’s Biggest Twin-Engine Passenger Plane

By: | October 2nd, 2015

Boeing’s latest twin-engine jet, called the 777-9X, is poised to become the largest and most efficient twin-engine jet in the world.

The 777-9X is the first aircraft of the 777X family, and the range of this plane is expected to reach beyond 8,700 miles.  The 777-9X will begin production in 2017. Boeing’s Everett plant, where this plane will be produced, is big enough to fit 25 football fields inside.

Bigger passenger capacity and a roomier cabin: For a unique 777X experience, the cabin interior of the plane has larger windows, a wider cabin, new lighting, and enhanced architecture. The plane has the capacity of carrying 400-plus passengers. 

Huge, folding wings: The wings of the plane are so big they have to be foldable. As a result, the aircraft will come with hinges on its wingtips. In order to fit into airports, the hinges will fold up to shorten the plane’s wingspan. The plane will have a wingspan of 235 feet, 5 inches (71.8 meters), with the hinged wingtips measuring 12 feet. 

Increased efficiency: This unique design will help in saving fuel. The 777-9X is expected to contribute 12 percent greater fuel savings than the Airbus A350. Moreover, the extra length of the wings is expected to increase efficiency and give the jet extra lift.
