Narrow-body aircraft

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A narrow-body aircraft (also known as a single aisle aircraft) is an airliner with a fuselage aircraft cabin width typically of 3 to 4 metres (10 to 13 ft)[according to whom?], and airline seat arranged 2 to 6 abreast along a single aisle [according to whom?][attribution needed][citation needed]. Narrow-body aircraft with a range not allowing transatlantic or transcontinental flights are commonly known as regional airliners.[citation needed]

In contrast, a wide-body aircraft is a larger airliner and is usually configured with multiple travel classes with a fuselage diameter of 5 to 7 metres (16 to 20 ft) and twin aisles. Passengers are usually seated 7 to 10 abreast. For comparison, typical wide-body aircraft can accommodate between 200 and 600 passengers, while the highest seating capacity of a narrow-body aircraft (the Boeing 757–300) is 289 passengers.
