cooperative

Narrow-body aircraft is a term referring to the fuselage of a passenger aircraft with a fuselage diameter of 3 to 4 m, a single row of aisles, and 2 to 6 seats per row . It is the opposite of a wide-body aircraft . Simply put, all small airplanes except large airplanes capable of long-distance international flights fall into this category.

In English, Narrow-Body, but the term Single-Aisle is more common. Aisle refers to traffic corridors in large buildings such as churches and cathedrals. On the contrary, the Wide -Body aircraft is called Twin-Aisle, which is divided into two passages. Sometimes it is used as Dual-Aisle or Double-Aisle.

In the case of a typical seating arrangement of 6 seats in one row (3 + 3), the fuselage diameter is about 3.7-3.8 meters (A320/B737).[1] In the case of 5 seats in 1 row (2+3), the fuselage diameter is about 3.3 meters (A220). Because the fuselage diameter is small, the ground clearance, which is the distance between the bottom of the fuselage and the ground, is low, and the distance between the main wing and the ground is short, making it difficult to install increasingly larger turbofan jet engines (CFM LEAP 1B 1.75 meters in the case of the 737 MAX), and the engines are sometimes mounted side by side at the rear of the fuselage rather than under the wings.

It is a concept that was relatively created in 1970 when the Boeing 747 , the first mass-produced wide-body airliner , entered service. In English, it is divided into the concept of wide body/common body, but in German, it is slightly different from the concept of standard body/wide body.

Models defined as cooperative aircraft include small aircraft such as business jets in principle, but in general, aircraft used for commercial purposes on routes of a certain size or larger in general airlines are considered cooperative aircraft. In other words, even if it is not a jet, a small civil aircraft is considered a cooperative aircraft.

Although four -shot cooperation often appears, the company tends to retire and retire due to the cost of operating. This is not an exception to Guangdong, so A340 and A380[2] The market share is given to the Boeing 777 and A350 , respectively , and is gone into history or pushed down little by little. In addition, the technology that has been applied to the four -legged optional airliner is partly transplanted in the age of the Cantonese medium -sized double -sized pair.

Cooperation was in 1970 Although the Boeing 747 's big success and subsequent Cantonese airliners have emerged, new devices have been actively produced and sold as demand increases due to an increase in direct flights since the 2000s. The reason is summarized as follows:

There are many errors that go beyond the prejudice that big planes are simply for long distances and small planes for short distances, and think of them as big planes because they are big companies like Korean Air or Asiana Airlines , or small planes because they are low-cost carriers. There is still a widespread perception that because it is a small plane, it is a low-cost airline accident, and because it is a large plane, it is a big airline. Moreover, there is also a lot of perception that it is dangerous because it is not a large plane. However, there is absolutely no relationship between the size of the aircraft and the quality and size of the airline. Looking at the world, there are large FSCs, such as Air Seoul or Jeju Air , that only operate large quantities of narrow planes such as the Boeing 737 and A321 , and there are also FSCs that are very small in scale...

The full service carrier we commonly speak of , that is, large airlines, also rolls out a number of "small plane", that is, cooperative. Many of the aircraft rolled by Korean Air or Asiana Airlines on the Gimpo-Jeju Airlines route are the cooperative. Similarly, foreign FSCs in Korea are often used for short -distance and A320 small groups. On the contrary, if you transport a medium to long range, the LCC we say is often injected with a large machine.

This perception is especially common among the middle-aged and older people, and there are many cases where they have the wrong perception that, even for short distances, the coordinated planes are more dangerous and have a higher risk of crashing because they are small planes. However, if you look at the reality, there are far more coordinated planes than the wide-range planes at this moment. It is also flying around the world and has no effect on the probability of an accident. Unlike the difference in accident probability and safety between a small car and a medium-to-large car in the event of a collision while driving on the ground, an aircraft moving at ultra-high speed in three dimensions is a completely different problem.

Europe's Ryanair, EasyJet, and America's JetBlue are all narrowbody enthusiasts, and all three companies are very safe airlines with no accidents for over 30 years.

Since the Boeing 747-100 , which was released in 1969 , is the first Guangdong body, all of the passengers created before the appearance of Boeing 747 in 1969 may be regarded as a cooperative. Therefore, only the types of gases are listed in Namuwiki, so only the representative gases are listed.
