The Boeing 777 Worldliner is an American-made long-haul passenger plane with two engines and a low-wing wing. Drive is provided by two Pratt and Whitney PW4000 or Rolls-Royce Trent 800 or General Electric GE90 engines. The flight of the prototype took place in 1994, and serial production began in 1995 and continues to this day. By August 2017, 1,512 copies of this aircraft had been produced. The unit price of the Boeing 777 varies from $261 million to $300 million depending on the version. The Boeing 777 is currently the largest twin-engine passenger aircraft in the world, with a strong emphasis on low fuel consumption, ease of use and the use of very advanced avionics. It is also the first Boeing passenger aircraft to use the fly-by-wire system. The machine is built in two basic versions: 777-200 and 777-300, which differ in body length by about 10 meters. A civilian transport version (Boeing 777F) was also created, the commercial debut of which took place in 2008. Depending on the version, the Boeing 777 can take up to 451 passengers on board.
