The Boeing 777 Family: Preferred by Passengers and Airlines Around the World

New Wing Design

The 777's advanced wing enhances the airplane's ability to climb quickly and cruise at higher altitudes and speeds than competing airplanes.

It also allows the airplane to carry full passenger payloads out of many high-elevation, high-temperature airfields.

Raked 6.5-foot wingtips have been added to the 777-200LR and 777-300ER to improve the overall aerodynamic efficiency of the wing. The raked wingtip helps reduce takeoff field length, increase climb performance and reduce fuel burn.

Propulsion


The three engine manufacturers developed more efficient and quieter turbofans to power the 777. All three engines offer excellent fuel efficiency.

Key factors in this performance are new, larger-diameter fans with wide-chord fan blade designs and bypass ratios ranging from 6-to-1 to as high as 9-to-1. This compares to the typical 5-to-1 ratio for the engines of previous twin-aisle jets.
