Narrow-body aircraft
A single-aisle aircraft (English narrow body, literally translated as " narrow body ", or single aisle, " a transition ") is an airliner with a fuselage diameter of between three and four meters and only one gear and up to six seats per row in Economy Class. The counterpart to the single-aisle aircraft is the widebody aircraft with more than 5 m body diameter and two aisles. Before the introduction of wide-body aircraft with the Boeing 747 1969 long-haul aircraft such as the Boeing 707, the Douglas DC -8 constructs or the Ilyushin Il -62 as the standard fuselage aircraft were due to space and comfort reasons, then barely.
Frequently produced single-aisle aircraft
Italics are no longer produced for over 20 years
6 seats per row (Economy Class )
- The future MS -21 to 380 cm inside width obtain and surpassing the Airbus A320 family.
- Airbus A320 family - with 396 cm outer and inner width 370 cm, the model with the largest fuselage cross -section of the single-aisle aircraft at the time.
- Boeing 707, 727, 737, 757 (all 376/354 cm) - the 757-300 is the standard fuselage aircraft with the largest passenger capacity (289 in 1 class), the 737 (all versions combined) of the most-produced passenger jet ( > 7,500 )
- Douglas DC -8 ( 373/350 cm) - the DC8-61/63/71/73 is 57,10 m with the longest Standardrumpflugzeug
- Ilyushin Il -62 (380/359 cm)
- Tupolev Tu -154 (380/358 cm)
5 seats per row (Economy Class )
- BAe 146 ( 356/338 cm) - in close seating also 6 per row
- Douglas Douglas DC-9/McDonnell MD-80/MD-90/Boeing 717 ( 334/314 cm)
- Fokker F-28/Fokker 70/Fokker 100 ( 330/310cm )
4 seats per row (Economy Class )
- Embraer E-Jets ( 301/274 cm) - a Business Class is partly made here by releasing the side seat.
- Sud Aviation Caravelle - 297 cm trunk diameter outside
Benefits
- An interpretation for a smaller number of passengers than in wide-body aircraft in which an excessive reduction would be necessary, is possible.
- The passenger capacity is sufficient for most short trips. Partial enough passengers are present during a day to fill the aircraft several times a day on the same route with passengers. So can many times be flown the same route every day.
- The volume of the trunk is better utilized because the upper roof part of the hull does not have to be hung like large aircraft.
Disadvantages
- Less passenger comfort due to perceived as cramped cabin, whose walls are severely bent and can create the feeling of a tube, especially on machines with a long torso. This is perceived as unpleasant, especially at longer flight times.
- Larger ratio of surface area to body volume than aircraft with a larger body diameter. By the relatively larger body surface area, the relative air drag increases as compared to larger aircraft fuselage diameters.
- In narrow-body aircraft with high passenger capacity is by the great length to the risk to put on -off or landing with the tail ( Tailstrike ).
- With only one gear in the passenger compartment, the time for boarding prolonged compared to an aircraft with two aisles and capacity significantly. This is particularly noticeable when deployed extra long aircraft on high-traffic routes. This was one reason why, for example, the B757 -300 could not hold up against much older pattern of Airbus A300 on short routes with high passenger volume itself.
