From the very beginning, the tradition in the aircraft building industry has been to build aircraft on a single scientific and technical basis. The designer creates the main model of the airframe and on its conceptual basis specific models are developed. The Boeing 767 300 passenger plane was created just as part of a specific concept. This wide-fuselage airliner is designed as an intermediate version between the previous machine, which had the usual fuselage volume, and a more powerful aircraft. The developers were tasked with creating comfortable conditions for passengers and at the same time reducing the cost of operating the aircraft.
As a result of the development, testing and refinement, the
Boeing 767 300 appeared, the interior layout of which turned out to be the most convenient for passengers. Seven seats in a row were installed in such a way that only one seat was located in the middle, between the passengers. And 87% of the places were either at the window or at the aisle. Boeing 767 300 became the first airliner in which passenger seats were placed in a row according to the formula 2 + 3 + 2. If you recall the domestic airliner
Tu-154, then it uses the 3 + 3 scheme. It would seem that thereβs only one less seat, but itβs crowded in the cabin of the Russian ship. And in an uncomfortable position are two out of six passengers.

The fact is that the fuselage of the Boeing 767 300 is almost one and a half meters wider than previously accepted standards. And thanks to this increase, not one, but two aisles appeared in the cabin. The salon has become not only more comfortable, but also more spacious. Depending on the configuration of the Boeing 767 300 aircraft, it can accommodate more than three hundred passengers. This option is designed for charter flights and does not involve the separation of lounges by level of comfort. In a more common form, when there are salons of different classes on board, 224 passengers are placed on the plane. At the same time, cargo compartments are capable of accepting more than one hundred cubic meters of baggage. This figure is more than forty percent higher than the similar characteristics of aircraft of this class.

If you look at the Boeing 767, a photo of which is shown on many screens, posters and booklets, you can easily see that it is more massive than other aircraft that fly on the same distances. By the way, its flight range is about eight thousand kilometers. And in this context, the question arises, why an increase in the external volume of the aircraft made it possible to improve its technical and consumer characteristics? There are no secrets or supernatural secrets in this case. Engineering, a
systematic approach, and the application of innovations from related fields of knowledge made it possible to create such a machine.
The first thing to say is the improvement of the aerodynamic 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 much more fuel. Simple logic suggests that the more fuel on board, the longer the flight can be. The flight, take-off and landing control system has also been upgraded. 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 modern avionics complex developed by an American company is used to control the aircraft.
