The 747-400 was announced by Boeing Commercial Airplanes in October 1985. Compared to the 747-300 the 747-400 has 6 ft (1.83 m) wing tip extensions and 6 ft (2 m) winglets, an all-new glass cockpit which dispensed with the need for a flight engineer. The 747-400 also improved on the -300 with tail fuel tanks, revised engines, an all-new interior, revised fuselage/wing fairings and newer in-flight entertainment. Like the 747-300, the passenger version of the 747-400 included the stretched upper deck (SUD) as a standard feature. The SUD was almost twice as long as the standard upper deck. It had previously been offered as a retrofit and first appeared on two Japanese 747-100 SR models.[1] While the wingspan was increased, the overall weight of the wings was decreased due to the use of composites and aluminum alloys.
