Boeing 777 (English: Boeing 777) is a long-haul twin-engine wide-body passenger plane manufactured by Boeing Company of the United States, and it is the largest twin-engine wide-body passenger plane in the world. The third-class cabin has a capacity of 283 to 368 passengers and a voyage of 5,000 nautical miles to 9,000 nautical miles (9,000 to 17,000 kilometers) [1]. Boeing 777 has a circular fuselage design and a landing gear with 14 tires. It is a twin-engine medium-and long-range wide-body passenger aircraft developed by Boeing Company of the United States. Boeing 777 is between Boeing 767-300 and Boeing 747-400 in specifications. On October 29th, 1990, the research and development plan was officially launched. On June 12th, 1994, the first Boeing 777 made its first test flight. On April 19th, 1995, it was awarded the European Joint Airworthiness Certificate and the type certificate of the Federal Aviation Administration. On May 30th, 1995, it was granted 180-minute extended flight. On May 17th, 1995, the first Boeing 777 was delivered to the user United Airlines. Boeing 777 is between B767-300 and B747-400 in size and range. It has the characteristics of flexible cockpit layout, wide range of range and different models that can meet the changing market demand. On January 14th, 2024, local time, when a Boeing 777 of Japan's All Nippon Airways took off and taxied at Chicago O 'Hare International Airport, the tip of the left wing collided with the tail of a Boeing 717 of Delta Air Lines. No casualties were reported, and the FAA launched an investigation into the accident [2]. Boeing 777 uses turbofan engines, mainly including three types: Pratt Whitney PW4000 series engines, GE90 series engines and Trent 800 series engines provided by rolls royce. [3] As early as the end of 1970s, Boeing announced 757 and 767 medium-range passenger planes, while Boeing's rivals Douglas and Lockheed, At the same time, Boeing found that there was a market gap between 747 and 767, so Boeing took a good look at this market and started to develop new aircraft. In 1986, Boeing began to study this problem in detail, and put forward a development plan called 767-X today. Based on the Boeing 767, a new aircraft with three engines was designed, which enlarged the fuselage and wingspan of the existing 767, carried 280 passengers and reached a range of 13,500 kilometers, hoping to save development time and cost. However, in the following three years, this idea was changed several times. At the same time, McDonnell Douglas and Airbus respectively proposed MD-11 and A330/340 aircraft similar to 767-X to seize this market. However, the Boeing 767-X scheme at that time was not welcomed by airlines. What airlines needed was a brand-new aircraft, so Boeing repositioned the whole development plan. On December 8, 1989, Boeing's board of directors passed the aircraft plan named 767-X, and set up a new R&D department to formally start R&D work.
