wide-body aircraft
Wide-body aircraft - a passenger aircraft in which there are two aisles between the passenger seats. The fuselage diameter in this type of aircraft is 5-6 meters, due to which a row of 6-10 seats can be placed across the cabin. For example, narrow-body aircraft have a fuselage diameter of 3-4 m, the maximum number of seats arranged in one row is 6.
Passenger capacity of these machines can reach up to 853 people (Airbus A380). The largest wide-body aircraft have a length of more than 70 meters.
The first serial passenger widebody aircraft became Boeing 747-100.
The appearance of this type of airliners in 60-70 years. due to the rapid pace of growth in air traffic congestion and air lines, especially in the areas of airports.
Through the use of a wider fuselage was able to dramatically increase passenger capacity (load) and to reduce the fuel consumption ratio per unit of transport capacity.
If to this efficiency was achieved by sealing aircraft passenger seat layout with the damage to their comfort, the increase of seats for passengers in the wide-body aircraft are not required to reduce the comfortable space flying. It attracts to buy tickets for the wide-bodied aircraft of many people.
Typically, airlines put widebody aircraft on flights of medium and long distances.
There are two-deck wide-body aircraft - A380, Boeing 747 - and single-deck - IL-96, IL-86, A340, A330, A310, Boeing 767, 777 and 787.
