In the aircraft building industry from the very beginninga tradition has been formed to build airplanes on a single scientific and technical basis. The designer creates the basic model of the airframe and on its conceptual basis, specific models are developed. Passenger Boeing 767 300 was created just in the framework of a certain concept. This liner with a wide fuselage is designed as an intermediate version between the previous car, which had the usual volume of the fuselage, and a more powerful aircraft. Before the developers was tasked to create comfortable conditions for passengers and at the same time reduce the cost of operating the aircraft.
As a result of the research, testing anddodok appeared Boeing 767 300, the layout of which was the most convenient for passengers. Seven seats in the row were installed in such a way that only one seat was located in the middle, between the passengers. And 87% of the seats were either at the window or at the aisle. Boeing 767 300 became the first liner in which passenger seats were placed in a row according to the formula 2 + 3 + 2. If you recall the domestic Tu-154 liner, then it uses a 3 + 3 scheme. It would seem that only one seat is smaller, but as in the cabin of the Russian liner closely. And in an uncomfortable position are two passengers out of six.
The fact is that the fuselage of the Boeing 767 300 is almostone and a half meters wider than previously adopted norms. And thanks to this increase in the cabin there were not one, but two passes. The salon became not only more comfortable, but also more capacious. Depending on the configuration of the Boeing 767 300, it can accommodate more than three hundred passengers. This option is designed for the implementation of charter flights and does not involve the separation of salons in terms of comfort. In a more common form, when there are salons of different classes on board, 224 passengers are accommodated in the plane. At the same time, cargo compartments are capable of taking more than one hundred cubic meters of baggage. This figure is more than forty percent higher than similar characteristics of aircraft of this class.
If you look at Boeing 767, whose photoare shown on many screens, posters and booklets, it is easy to see that it is more massive than other planes that make flights to the same distances. By the way, the range of his flight is about eight thousand kilometers. And in this context, the question arises as to why the increase in the external volume of the aircraft has made it possible to improve its technical and consumer characteristics? There are no secrets or supernatural secrets in this case. Engineering thought, a system approach and the application of innovations from related fields of knowledge made it possible to create such a machine.
The first thing to be said about is the improvementaerodynamic properties of the airframe. The second component of success is the use of more powerful engines. Boeing 767 300 has the ability to take on board significantly more fuel. Simple logic suggests that the more on board fuel, the longer the flight can be. The flight control, take-off and landing system was also modernized. The cockpit contains a large number of sensors, indicators and other devices, but they are very compact. In particular, it can be noted that the most advanced avionics system developed by the American company is used to control the aircraft.
