Boeing 747-400 British Airways


From Wikipedia, the free encyclopedia


The Boeing 747-400 is an American wide-body jet airliner developed by Boeing Commercial Airplanes. Derived from the earlier versions of the Boeing 747, the 747-400 retains the four-engine wide-body layout of its predecessors, whilst incorporating numerous technological and structural changes to produce a more efficient airframe. Its most distinguishing features versus preceding 747 models are 6-foot (1.8 m) winglets mounted on 6-foot (1.8 m) wing tip extensions, which are found on all 747-400s except for Japanese domestic market versions. It is the best-selling model of the Boeing 747 family of jet airliners.

The 747-400 is equipped with a two-crew glass cockpit, which dispenses with the need for a flight engineer, along with more fuel-efficient engines, an optional fuel tank in the horizontal stabilizer, and revised fuselage/wing fairings. The aircraft also features an all-new interior with upgraded in-flight entertainment architecture. As on the 747-300, passenger variants include a stretched upper deck as standard. The 747-400 can accommodate 416 passengers in a typical three-class layout, 524 passengers in a typical two-class layout, or a maximum capacity of 660 passengers in a high–density one-class configuration with the 747-400D variant, and can fly non-stop for up to 7,670 nautical miles (14,200 km) with maximum payload, depending on model.

Northwest Airlines first placed the 747-400 in commercial service on February 9, 1989. The 747-400 was produced in passenger (-400), freighter (-400F), combi (-400M), domestic (-400D), extended range passenger (-400ER) and extended range freighter (-400ERF) versions. The last 747-400, a -400ERF, was delivered in 2009. The 747-400 is the second-most recent version of the 747 family, having been superseded by the improved Boeing 747-8.
