The four-engine Boeing 747-400 is a wide-body, long-haul, passenger aircraft, built on a double-decker design by Boeing Commercial Airplanes. This airliner, although designed on the basis of previous models of this family, is structurally a new aircraft. The new airliner has become much more capacious than previous versions of the Boeing 747 family of aircraft. Thanks to the new engines, the noise level of the serial Boeing 747-400, was two times less than that of +747And fuel efficiency has increased by 25 percent.

In the early 1984, the company «Boeing Commercial Airplanes», beginning work on a new plane, due to the fact that modification 747-300, did not raise sales, as the company wanted. And to all the added problem of development of competing aircraft, such as the McDonnell Douglas MD-11, Airbus A330 и Airbus A340, which in the future could take part of the market from the company «Boeing». And in September of that year, at the Farnborough Air Show, it was announced that a new airliner, the Boeing 747 Advanced Series 300, would be built. Officially, the same program was launched on October 22 1985 of the year. The first customer for the new airliner was the American airline Northwest Airlines, whose initial order was for the supply of 10 aircraft. Later, the list of major customers was expanded by such airlines as “Cathay Pacific","Japan Airlines","Singapore Airlines","British Airways","United Airlines", French"Air France"And the German"Lufthansa". The main customers also acted as consultants when designing a new airliner. After approval of the project, the aircraft received the designation Boeing 747-400.

The new aircraft had extended wings, whose span now was 64,44 meters, which is 4,8 meters larger than the 747-300. Now the wings of the Boeing 747-400, were completed with wingtips, the so-called winglets. When building the wing of the aircraft, composite materials were used, this had a positive impact on the weight of the structure. To increase the flight range of the aircraft, an additional fuel tank was installed.

The basis of the powerplant Boeing 747-400, performed by new economical turbojet Pratt & Whitney PW-4056 engines with 252,4 kN thrust. Subsequent models also installed General Electric CF6-80-C2B1Fs, CF6-80-C2B1F1s motors, and RollsRoyce RB-211-524G engines with 258,0 kN thrust.

On Boeing 747-400, it installed a new digital avionics, consisting of six multi-function display and the new avionics. This solution has reduced the crew to two.

The upper deck was also extended, now it has become two times longer than the original version of a family of airliners Boeing 747.

Boeing 747-400, in three classes, which can accommodate 416 passenger seats. The interior configuration of economy and business, can accommodate 524 passengers. A maximum, economy class, passenger capacity is 660 people.

Final assembly of the aircraft was carried out at the company «Boeing», located in the city of Everett. January 26 1988, when the plane rolled off the assembly hangar, the company had more than 100 orders for this aircraft.

And on April 29 1988, the Boeing 747-400, the air rose. The first test flight lasted more than two hours. The test involved four aircraft Boeing 747-400, with different engines. And on January 10 1989, the airliner received the first FAA flight certificate. 26 January of the same year, Boeing 747-400 was transferred to the first customer in the person of the airline "Northwest Airlines". The first flight on this aircraft was made in the direction of “Minneapolis - Phoenix”, 9 February 1989 year.

  • - Boeing 747-400 ER, extended-range airliner flight. The aircraft was put into operation in October 31 2002 years.

  • - Boeing 747-400 D, a version developed specifically for Japanese airlines, for use at regional and local routes. The first flight of this version took place on 18 March 1991.

  • - Boeing 747-400 ERF, air cargo version with extended range. The first aircraft of this version was passed in October 17 2002, the French airline «Air France».

In addition to civilian and cargo variants, on the basis of the Boeing 747-400 produced aircraft for military purposes.

Boeing 747-400, became the best-selling aircraft of all family «747». During its production of 1988 2009 year 694 units were produced this version of an airliner. Of these, the basic passenger version 747-400, produced and delivered 442 aircraft.
