33 Facts About Boeing 777

Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes.

The 777 was designed to bridge the gap between Boeing's other wide body airplanes, the twin-engined 767 and quad-engined 747, and to replace older DC-10s and L-1011 trijets.

The Boeing 777 entered service with the launch customer, United Airlines, in June 1995.

In November 2013, Boeing announced the 777X development with the -8 and -9 variants, both featuring composite wings with folding wingtips and General Electric GE9X engines.

In 1978, Boeing unveiled three new models: the twin-engine Boeing 757 to replace its 727, the twin-engine 767 to challenge the Airbus A300, and a trijet 777 concept to compete with the DC-10 and L-1011.

The trijet Boeing 777 was later dropped, following marketing studies that favored the 757 and 767 variants.

In 1986, Boeing 777 unveiled proposals for an enlarged 767, tentatively named 767-X, to target the replacement market for first-generation wide-bodies such as the DC-10, and to complement existing 767 and 747 models in the company lineup.

Boeing 777 opted for the twin-engine configuration given past design successes, projected engine developments, and reduced-cost benefits.

Boeing 777 was the first commercial aircraft designed entirely by computer.

Boeing 777 developed its high-performance visualization system, FlyThru, later called IVT to support large-scale collaborative engineering design reviews, production illustrations, and other uses of the CAD data outside of engineering.

Boeing 777 was initially not convinced of CATIA's abilities and built a physical mock-up of the nose section to verify its results.

In 1999, Boeing 777 announced an agreement with General Electric, beating out rival proposals.

Under the deal with General Electric, Boeing agreed to only offer GE90 engines on new 777 versions.

In 2007, orders for second-generation 777 models approached 350 aircraft, and in November of that year, Boeing announced that all production slots were sold out to 2012.

In 2010, Boeing 777 announced plans to increase production from 5 aircraft per month to 7 aircraft per month by mid-2011, and 8.

In January 2016, Boeing confirmed plans to reduce the production rate of the 777 family from 8.

Boeing 777 was redesigning the inboard flap fairings to reduce drag by reducing pressure on the underside of the wing.

The outboard raked wingtip was to have a divergent trailing edge, described as a "poor man's airfoil" by Boeing 777; this was originally developed for the McDonnell Douglas MD-12 project.

Mindful of the long time required to bring the 777X to the market, Boeing continued to develop improvement packages which improve fuel efficiency, as well as lower prices for the existing product.

Boeing introduced a number of advanced technologies with the 777 design, including fully digital fly-by-wire controls, fully software-configurable avionics, Honeywell LCD glass cockpit flight displays, and the first use of a fiber optic avionics network on a commercial airliner.

Boeing 777 made use of work done on the cancelled Boeing 777 7J7 regional jet, which utilized similar versions of the chosen technologies.

In 2003, Boeing 777 began offering the option of cockpit electronic flight bag computer displays.

In 2013, Boeing announced that the upgraded 777X models would incorporate airframe, systems, and interior technologies from the 787.

In designing the 777 as its first fly-by-wire commercial aircraft, Boeing decided to retain conventional control yokes rather than change to sidestick controllers as used in many fly-by-wire fighter aircraft and in many Airbus airliners.

The Boeing 777's windows were the largest of any current commercial airliner until the 787, and measure 15-inch by 10-inch in size .
