Boeing 777 Boeing
777
Long-Range Jetliner

DESCRIPTION:
What eventually became the 777 project began when several airlines expressed a desire for an airliner with a capacity in between the 767-300 and 747-400. The 777 is designed for both intercontinental and transcontinental routes and is targeted primarily at the Pacific rim market. The overall design is typical of previous Boeing airliners except it is equipped with only two engines, unlike the transcontinental 707 and 747.
To achieve flight certification on such a design, Boeing had to ensure new levels of reliability in engines, avionics, and a fly-by-wire control system as well as the ability to maintain level flight for three hours even with one engine inoperative. Like the 747, the 777 includes three powerplant options depending on airline preference, and these air-breathing engines are the most powerful ever fitted to any aircraft. To give some idea of the size of the 777, the engine nacelles are nearly as wide as the fuselage of the 737. However, some airlines requested the large airliner be able to use the passenger gates designed for the DC-10 and smaller aircraft, so the outer wing panels are designed to fold upward on some models.
Five major variants of the 777 have been designed to date. Base models are the 727-200 and stretched 777-300, and serveral extended and long range models have also been developed. At least 700 aircraft had been built by early 2008.
