The Boeing 777 is a wide-body twinjet airliner developed and manufactured by Boeing Commercial Airplanes. The 777 was designed to bridge the gap between Boeing’s 767 and 747, and to replace older DC-10s or L-1011s. It is recognizable for its large-diameter turbofan engines, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped tail cone.
About Boeing 777 in brief
The Boeing 777 is a wide-body twinjet airliner developed and manufactured by Boeing Commercial Airplanes. The 777 was designed to bridge the gap between Boeing’s 767 and 747, and to replace older DC-10s or L-1011s. It can accommodate up to ten abreast seating layout and has a typical 3-class capacity of 301 to 368 passengers, with a range of 5,240 to 8,555 nautical miles. It is recognizable for its large-diameter turbofan engines, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped tail cone. In November 2013, Boeing announced the 777X development with the -8 and -9 variants, scheduled to enter service by 2020. As of August 2019, more than 60 customers had placed orders for 2,049 aircraft of all variants, with 1,609 delivered. The most common and successful variant is the 777-300ER with 844 aircraft ordered and 810 delivered. By March 2018, the 777 had become the most-produced Boeing wide- body jet, surpassing the Boeing 747. Emirates was the largest operator with 163 aircraft. The Boeing 777 has been involved in 28 aviation accidents and incidents, including seven hull losses resulting in 541 fatalities along with three hijackings. The original 777 with a maximum takeoff weight of 545,000–660,000 lb was produced in two fuselage lengths: the initial -200 was followed by the extended-range 777-200ER in 1997; and the 33.
25 ft longer 777- 300 in 1998. The longer range 777-100ER entered service in 2004, the ultra long-range777-200LR in 2006, and the 777F freighter in 2009. In 1986, Boeing unveiled proposals for an enlarged 767 tentatively named 767-X, to replace the existing 767, 727, and 747. The trijet 777 concept was later dropped, following marketing studies that favored the 757 and 767 variants. The 767 was left with a capacity of 757-300 and 727-400 and the 747-400-400 was left in with a 757 -300-300 capacity and a 767 -300ER capacity. By the late 1980s, Boeing was targeting the replacement market for first-generation wide-bodies such as the DC- 10, DC-11, and L- 1011 as well as the existing 747 and 747 models in the Boeing 767 lineup. It initially competed with Airbus A340 and McDonnell Douglas MD-11. Both now out of production, and currently competes with the Airbus A330-300, and newer Airbus A350 XWB. It has been ordered and delivered more than any other wide-Body airliner; as of August 2019, more than 60 customers have placed orders for 2,000 aircraft of all variants.
