Jumbo jet, a giant reactant, is the name of this aircraft all over the world. It is indeed very large, this quality is both a virtue and a disadvantage.
In 1970, when the 747 was introducedairlines, many carriers doubted that the funds invested in his purchase would pay off. Initially, these fears were justified, the fuel crisis of the seventies led to a sharp decrease in the intensity of air transport. However, Boeing is for that and Boeing, to withstand the challenges of market conditions.
In the class of passenger liners intendedfor long-haul flights with a large number of people on board, this aircraft was unparalleled, so the refusal of a number of airlines to operate it did not cause panic among one of the world's leading manufacturers of aircraft, but only made them think about improving their car. In the autumn of 1984, the development of a modification 747-300 began, and in the spring of 1985 it was launched under the name "Boeing 747,400". In fact, it was already a new aircraft, although it had a lot in common with the prototype, in particular, its appearance.
Scheme Boeing 747 400 remained the same.Two-deck layout with a high-placed pilot cabin, four engines on the pylons under the wing, each of which is more powerful than all the engines of the 707th Boeing combined, enormous carrying capacity and capacity combined with high speed - here is a brief description of the updated "Jambo Jet". The number of passengers it can translate at one time is comparable to the number of tourists on an ocean cruise liner. So, in 1991, Boeing 747,400 Israeli airline El Al delivered to its historical homeland over 1100 returnees from Ethiopia. In normal mode, the number of passengers carried with luggage reaches five hundred.
In the modified design applied newalloys, the technologies of which were developed for aircraft of the later 757th and 767th series, as a result of which the glider became almost three tons lighter. The wings extended by 3.7 meters were equipped with vertical ends 180 cm high, which improved the stability of the liner when it made a maneuver.
Improved passenger comfort on board the Boeing 747. A photo of the cabin demonstrates the presence of individual entertainment complexes, monitors mounted in the seat, even in the second class.
Avionics has become completely digital, which reduced the number of crew members to two, eliminating the flight engineer.
Work to further increasepassenger capacity and carrying capacity, planned by the management and engineers of the company, are currently frozen, as in recent years, sales of the liner decreased. In total, over 1,400 airliners of this type were produced. The Boeing 747,400, in operation since 1989, accounts for about a third of the world's aircraft fleet in this series.
Such an expensive plane can affordacquire only the largest airlines in the world, such as KLM, PanAm, Katay, Air France, British Airways, Lufthansa and other equally well-known carriers. In Russia, the operators of this airliner are Transaero and Air Bridge Cargo.
