Jumbo Jet, giant reaktivnik, so call this aircraft worldwide.It really is very big, it's quality is both advantage and disadvantage.
In 1970, when the 747 was presented to leading airlines, many carriers doubted that invested in its purchase pays off.At first, these fears were justified, the fuel crisis of the seventies led to a sharp decrease in the intensity of the air transport.However, Boeing Boeing, and the fact that the challenges of the market situation.
In class passenger aircraft designed for long-haul flights with a large number of people on board the plane had no equal, so the failure of a number of airlines from its operation has not caused panic in one of the world's leading manufacturers of aircraft, but only forced to thinkon improving their car.In the fall of 1984 began to develop a modified 747-300, and the spring of 1985 he was named "Boeing 747 400" was launched in a series.In fact, it was the new plane, although the prototype he had much in common, in particular the appearance.
scheme Boeing 747 400 remained unchanged.Two deck layout with a highly placed cockpit, four engines on pylons under the wings, each of which is more powerful than all the engines of the Boeing 707 combined, and a huge load capacity, combined with high speed - that's a brief description of the updated "Jumbo Jet".Number of passengers, which it can convert at a time, comparable to the number of tourists on the ocean cruise liner.For example, in 1991 747 400 Israeli airline El Al has delivered to their historic homeland over 1100 repatriates refugees from Ethiopia.In normal mode, the number of passengers with luggage up to five hundred.
In the modified design used new alloys and technologies which have been developed for the aircraft later 757 th and 767 th series, resulting in a glider is lighter by nearly three tons.Console elongated 3.7 meter wing endings supplied vertical height of 180 cm, which improved the stability of the liner when making a maneuver.
increasing comfort of passengers on board the Boeing 747 cabin Photo shows the presence of individual entertainment centers, which monitors mounted in the seat, even in the second grade.
Avionics become fully digital, which reduced the number of crew members to two, eliminating the flight engineer.
work to further increase passenger and cargo capacity, plan management and engineers of the company, currently frozen, as in recent years, sales were down liner.There were produced over 1400 aircraft of this type.747 400 is operated since 1989, is about a third of the world fleet of this series.
such an expensive aircraft can afford to purchase only the world's largest airlines, such as KLM, Panama, Cathay, Air France, British Airways, Lufthansa and other equally well-known carriers.In Russia, the operators of the liner are Transaero and Air Bridge Cargo.
