Narrow-body aircraft

A narrow-body aircraft ( english narrow body ) or single-aisle aircraft (Engl. Standard body ) is a commercial aircraft with only one gangway (Engl. Single aisle ) and up to six seats per row in economy class , in an exceptional case even seven. The use of the terms is only common in jet aircraft .

Detached from the general term “standard fuselage aircraft” or “narrow-fuselage aircraft”, aircraft manufacturers such as Airbus or Boeing use the term standard body, which is also firmly defined for a standardized fuselage diameter. Boeing uses the term for the fuselage diameter, which was first used for the Boeing 707 and then adopted in unchanged form for the 727 , 737 and 757 types . The aircraft manufacturer Airbus uses the term “standard fuselage aircraft” for the four model series of its Airbus A320 family that have the same standardized fuselage diameter.

History of the term narrow-body aircraft

Airbus A320 and Boeing 737-800

The introduction of the Boeing 747 , which had a significantly larger trunk diameter than the previously developed jetliners, was in the 1960s, the term wide-bodied aircraft (wide body) introduced. Previously developed types, such as the Boeing 707 , Boeing 727 , Douglas DC-8 or Convair CV-990 , were then referred to as "standard fuselage aircraft " (standard body) . This term should make it clear that these older jet airliners had a significantly narrower fuselage diameter than the new Boeing 747, McDonnell Douglas DC-10 and Lockheed L-1011 and was to be understood in the sense of conventional standards ; he did not refer to a uniform standard measure. It was not until the late 1970s that the term “ narrow body” , which can now be found predominantly in press releases or in specialist literature, slowly established itself . The freighter variants of narrow-body aircraft are still referred to as standard bodies to this day . A “standard hull freighter” is defined as a single-aisle aircraft with a loading capacity of up to 50 tons. The “standard hull freighters” include, for example, the types Boeing 707, 727, 737 , 757 , Douglas DC-8, DC-9 , MD-80 , MD-90 as well as the Airbus A320 family or the BAe 146 .

Often produced narrow-body aircraft

A319 cabin , 6 seats per row
Cabin DC-9 , 4 (Business) or 5 seats (Economy Class) per row
Embraer E-170 cabin , 4 seats per row

Italics have not been produced for over 20 years.

7 seats per row (Economy Class)

6 seats per row (Economy Class)

  • Airbus A320 family , with 396 cm outside and 370 cm inside width, the model with what is currently the largest fuselage cross-section of narrow-fuselage aircraft
  • Boeing 707 , 727 , 737 , 757 (all 376/354 cm); the 757-300 is the narrow-body aircraft with the largest passenger capacity (289 in one class), the 737 (all variants together) the most frequently produced passenger jet (over 8,000 pieces)
  • Douglas DC-8 (373/350 cm); the DC-8-61 / 63/71/73 is the longest narrow-body aircraft at 57.10 m
  • Hawker Siddeley Trident (344 cm inner width)
  • Ilyushin Il-62 (380/359 cm)
  • Tupolev Tu-154 (380/358 cm)

5 seats per row (Economy Class)

4 seats per row (Economy Class)

3 seats per row

advantages

  • A design for a lower number of passengers than in the case of wide-body aircraft , which would require too much reduction, is possible.
  • The passenger capacity is sufficient for most short trips. Sometimes there are enough passengers during one day to fill the aircraft with passengers several times a day on the same route. This means that the same route can be flown several times a day.
  • Better use is made of the volume of the fuselage, as the upper part of the roof of the fuselage does not have to be suspended, as is the case with large-capacity aircraft.

disadvantage

  • Less passenger comfort due to the cabin, which is perceived as cramped, the walls of which are strongly curved and can create the feeling of a tube, especially in machines with a long hull. This can be perceived as uncomfortable, especially with longer flight times.
  • In narrow-body aircraft with a high passenger capacity is composed by the great length of the danger off or landing with the rear set up ( tailstrike ).
  • With only one aisle in the passenger area, the boarding time is considerably longer compared to an aircraft with two aisles and the same capacity. This is particularly noticeable when particularly long aircraft are deployed on highly frequented routes.
