BOEING 747-400 Jumbo Jet
As a further development of the 747-300 stretched upper deck aircraft, Boeing launched the 747-400 in October,
1985, on the basis of an order for 10 aircraft placed by Northwest Airlines; this was followed by a 14-aircraft
order from Singapore Airlines in March, 1986. The 747-400 is a greatly improved variant of the 747-300, with
significant savings achieved through the use of lighter aluminum alloys and certain hardware adapted from the 757
and 767.
The 747-400 differs from the -300 in having numerous changes to the structure and systems. The wing span has
been increased by the use of 6 ft (1.8 m) extensions on the wingtips with upward-pointing winglets for improved
aerodynamics. The new wingtips increase the aspect ratio of the wing, thereby reducing induced drag and
increasing the range of the aircraft by 3%. Extended wingtips plus winglets increase overall span to 212 ft. 2 in.
(64.67 m.). Boeing says the -400 consumes 8 to 13% less fuel than the 747-300, and up to 17% less than the
747-200.
The changes include a choice of advanced technology, lean-burn engines such as the 56,000 lb (25,402 kg) thrust
Pratt & Whitney PW4056, the 59,000 lb (26,339 kg) thrust General Electric CF6-80C2, and the 60,000 lb
(26,785 kg) thrust Rolls-Royce RB211-524G/H.
The two-crew EFIS (Electronic Flight Instrument System, which is the electronic instrumentation in modern
aircraft cockpits in which large multifunction CRT displays replace traditional electro-mechanical instruments;
also termed "glass cockpit") cockpit instrumentation improvements of the 757 and 767 have been adapted to the
747-400, to transform a three-crew-member analog cockpit with electro-mechanical instruments to a full digital,
two-crew flight deck with six multi-function CRT displays. The design provides even more capability than the
757/767 flight deck.
Depending on engines and other variables, the gross weight of the 747-400 ranges from 800,000 to 870,000 lb.
Due to the added fuel capacity, more fuel efficient engines, and the new wingtips, the 747-400 has a range up to
8,400 mi (13,400 km).
The 747-400 powered by PW4056 turbofans, first flew in April, 1988 and entered service in January, 1989 with
Northwest. On June 27, 1988, this first -400, a 747-451 for Northwest Airlines, set a new official weight record
by reaching an altitude of 2,000 meters at a gross weight of 892,450 lb. Qantas Airways set the world distance
record for commercial airliners by flying its first 747-400 from London to Sydney non-stop, a distance of 11,156
mi. (18,000 km) in 20 hr 9 min.
Japanese airlines have bought the 747-400D, without winglets and with other minor changes, for high intensity
Japanese domestic routes. The undercarriage, wing and fuselage are strengthened to accommodate a high number of
