Boeing B747-400

The Boeing 747-400 is a four-engine widebody commercial jet airliner, manufactured by Boeing Commercial Airplanes. The -400 series is the best-selling model in the successful 747 family.   Its most distinguishing feature from the other 747 models are its winglets, although the -400D does not feature any. With seatings for a maximum of 624 people, the 747-400 can fly non-stop for 7,670 nautical miles (14,200 km), depending on model.

The 747-400 was announced by Boeing Commercial Airplanes in October 1985. Compared to the 747-300 the 747-400 has 6 feet (1.8 m) wing tip extensions, 6 feet (1.8 m) winglets, and a glass cockpit, which dispensed with the need for a flight engineer. The 747-400 also improved on the 300 version with the addition of a fuel tank in the horizontal stabilizer, engines with improved fuel efficiency and higher thrust, an all-new interior, revised fuselage/wing fairings and newer in-flight entertainment. While the wingspan was increased, the overall weight of the wings was decreased due to the use of composites and aluminum alloys.
