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 a part of the market from the Boeing company. And in September of the same year, at the Farnborough Air Show, the creation of a new airliner, the Boeing 747 Advanced Series 300, was announced. Officially, the program was launched on October 22, 1985. The first customer for the new airliner was Northwest Airlines, an American airline, whose initial order was for 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". Major customers also acted as consultants in the design of the new airliner. After the approval of the project, the aircraft received the designation Boeing 747-400.

On the new aircraft, the wings were lengthened, the span of which was now 64,44 meters, which is 4,8 meters more than the 747-300. Now the wings of the Boeing 747-400 are equipped with wingtips, the so-called winglets. During the construction of the aircraft wing, composite materials were used, this positively affected the weight of the structure. To increase the flight range, an additional fuel tank was installed on the aircraft.

The power plant of the Boeing 747-400 was based on the new economical Pratt & Whitney PW-4056 turbojet engines with a thrust of 252,4 kN. Subsequent models also used General Electric CF6-80-C2B1Fs, CF6-80-C2B1F1s engines and RollsRoyce RB-211-524G engines with a thrust of 258,0 kN.

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.

On April 29, 1988, a Boeing 747-400 took off. The first test flight lasted over two hours. The tests involved four Boeing 747-400 aircraft, with different engines. And on January 10, 1989, the airliner received its first FAA flight certificate. On January 26 of the same year, the Boeing 747-400 was handed over to the first customer, Northwest Airlines. The first flight on this aircraft was made in the direction "Minneapolis - Phoenix", February 9, 1989.
