Passenger aircraft "Boeing 767-300": characteristics, history, operation
In the product line of the largest manufacturer of civilian and military aircraft Boeing model present This wide-body airliner, designed for long-haul routes, more often than other aircraft found on transatlantic flights.
In 1972, some time after entering the 747 wide-body aircraft line, Boeing launched the design process for the next model under the code name 7X7. The initial intention of creating a short-range, short-range, short-range passenger aircraft did not arouse interest among potential customers, and the developer switched to creating a transcontinental airliner. After working through several layout options, the designers chose a scheme resembling a European Airbus A-300. In these years, aviation technology has reached an incredibly high level.There were powerful and economical aircraft engines of a new generation, composite structural materials, new trends in aerodynamics were established. Improved fuel efficiency. All this was applied to the Boeing 757 and 767 aircraft, which had unified cockpits, which were called glass cockpits. Such technologies meant the presence of displays instead of dial gauges, reduction of the crew to two people, the replacement of the navigator by the FMS flight control system. Computer modeling was widely used.
The release of the aircraft model 767 was planned at the Everett plant. The main model was initially "Boeing 767-200", its production started 07/14/1978.
After a series of test flights and testing of several samples with different engines, the company certified the liner. Deliveries began in October 1982.
The modifications of the Boeing 767-300 and 767-300 ER, which appeared in 1983, aroused great interest among the airlines. Having made the very first flight on 1/30/1986 (the beginning of development was 1984), the aircraft "Boeing 767-300", whose scheme resembles the famous "Airbus A-320", went into commercial operation on 10/20/1986. The first customer and owner was the famous airline Japan Airlines.
"Boeing 767-300", the cabin layout of which allows you to take a large number of passengers on board and deliver them from one continent to another, was released in the amount of 104 pieces. According to statistics, this model crossed the Atlantic Ocean more often than all other aircraft in the aggregate.
"Boeing 767-300" was extended by 6.43 meters modification of the earlier version - "Boeing 767 - 200". In addition to inserting two additional sections, the company carried out other improvements: the liner was reinforced with the fuselage and chassis design. Gradually, this version was improved, received the English engines Rolls-Royce RB 211. Scope of the aircraft - long routes in Europe and Asia, where its high reputation contributed a lot to 20-30% lower fuel costs compared to previous aircraft.
With a wide cabin, the Boeing 767-300 is able to take on board from 218 passengers (maximum up to 350 people) with a crew of 2 people. The aircraft has been assigned the ICAO code B763. With an aircraft length of 54.9 m and a wingspan of 47.6 m, the width of the cabin is from 4.72 to 5.03 m. Take-off weight is 159.2 tons; empty liner mass - 90.1 tons, cruising speed reaches 851 km / h. At this speed, the flight distance is 7900 km (in the version 767-300 ER - 11065 km).The power plant is represented by 2 General Electric CF6-80C2-84F turbofan engines (their thrust is 2 x 26260 kg / s), there are options with Rolls-Royce RB 211 engines.
The wings in 2010 received a new ending, called winglets.
The required length of the runway under standard ISA conditions while the vehicle is at sea level is 2300 m.
The Boeing 767-300, the cabin layout of which is a combination of two longitudinal aisles and several rows of seats distributed over the 2 + 3 + 2 system (economy class), is designed for flights for many hours. Therefore, the cabin has several spacious compartments for hand luggage, an increased number of bathrooms, comfortable lighting, and excellent sound insulation. Aircraft seats of many airlines are equipped with multimedia systems.
There were practically no problems with the commissioning of the model. For example, for the entire first year of use of the liner, 96.1% of the aircraft took off and landed without delay for technical reasons. The economy and comfort of the liners perfectly met the requirements of the airlines. After changes in flight safety regulations (ETOPS),which allowed twin-engine airplanes to fly on such routes, where the distance from the nearest emergency landing airfield should not exceed 120 minutes of flight time (previously this value was 90 minutes), sales of the Boeing 767-300 increased. Especially intensively the machine was operated on transatlantic lines.
The described aircraft is popular, as well as the other modifications of this model, among Russian airlines, the possibility of delivering a large number of passengers on charter flights is especially appreciated.
But the air traffic crisis after 2001 led to a drop in demand for the Boeing 767-300.
