A narrow-body aircraft or single-aisle aircraft is an airliner arranged along a single aisle, permitting up to 6-abreast seating in a cabin less than 4 metres (13 ft) in width. In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than 5 metres (16 ft), allowing at least ...
The largest wide-body aircraft are over 6 m (20 ft) wide, and can accommodate up to eleven passengers abreast in high-density configurations. By comparison, a typical narrow-body aircraft has a diameter of 3 to 4 m (10 to 13 ft), with a single aisle, [1] [6] and seats between two and six people abreast. [7]
The Boeing 737 is an American narrow-body aircraft produced by Boeing at its Renton factory in Washington.Developed to supplement the Boeing 727 on short and thin routes, the twinjet retained the 707 fuselage width and six abreast seating but with two underwing Pratt & Whitney JT8D low-bypass turbofan engines.
The Boeing 737 Next Generation, commonly abbreviated as 737NG, or 737 Next Gen, is a twin-engine narrow-body aircraft produced by Boeing Commercial Airplanes. Launched in 1993 as the third generation derivative of the Boeing 737, it has been produced since 1997. [4] The 737NG is an upgrade of the 737 Classic (–300/–400/–500) series.
In the early 1970s, following the launch of the first wide-body airliner, the 747, Boeing began considering further developments of its narrow-body 727. [4] Designed for short and medium length routes, [5] the trijet was the best-selling jetliner of the 1960s and a mainstay of the U.S. domestic airline market.
The Airbus A320 family are narrow-body (single-aisle) aircraft with a retractable tricycle landing gear and powered by two wing pylon-mounted turbofan engines. After the oil price rises of the 1970s , Airbus needed to minimise the trip fuel costs of the A320.
Since 2000, both narrow-body and wide-body trijet production has ceased for almost all commercial aircraft, being replaced by twinjets. As of 2016, the Falcon 7X, 8X, and 900 business jets, all of which use S-ducts, are the only trijets in production.
The narrow-body and wide-body airliner market is dominated by Airbus and Boeing, and the regional airliner market is shared between ATR Aircraft, De Havilland Canada, and Embraer. Setting up a reliable customer support network, ensuring uptime, availability and support 24/7 and anywhere, is critical for the success of airliner manufacturers.
