Qantas received the first delivery of a 747-400ER registration VH-OEF on October 31, 2002; however, this was the second airplane built.
United's deployment of them also reflected a change in emphasis from Asian hubs to domestic hubs.The 747-400's airframe features extended and lighter wings than previous 747s, capped by winglets.
George Dimitroff, head of valuations for FlightGlobal, estimated the aircraft's value before the incident at about $8 million. The first -400ERF was delivered to The 747-400BCF (Boeing Converted Freighter), formerly known as the 747-400SF (Special Freighter), is a conversion program for standard passenger 747-400s. The -400D may be converted to the long-range version if needed. Airlines using the 747-400 have been retiring the model, replacing it with more fuel efficient aircraft. When a 26-year-old 747-400 owned by Delta flew through a violent hailstorm, the company indicated it was likely the aircraft would be scrapped.
For reduced Final assembly of the first 747-400 began at Boeing's The 747-400 flew for the first time on April 29, 1988, under the command of test pilot James Loesch and co-pilot Kenneth Higgins.As the flight test program proceeded, Boeing encountered problems in the 747-400's production process, leading it to disclose delivery delays of up to one month for the first 20 aircraft built.In May 1989, one week before the initial delivery to the 747-400's first European customer, KLM, the After the first 747-400 deliveries, Boeing began production on more variants of the aircraft. With 694 delivered over the course of 20 years from 1989 to 2009,Following its introduction in 1969, the Boeing 747 became a major success with airlines and the flying public.In 1982, Boeing introduced a two-crew glass cockpit, new engines, and advanced materials on its 757 and 767 twinjets.By early 1984, company officials had identified five development objectives for the latest 747 upgrade: new technologies, an enhanced interior, a 1,000 Seven early customers, namely British Airways, Cathay Pacific, KLM, Lufthansa, Northwest, Qantas, and Singapore Airlines, formed a consultative group to advise Boeing on the 747-400's design process.The 747-400's wingspan was stretched by 17 feet (5.2 metres) over the Classic 747 through wingtip extensions.
The Boeing 747-400 is a wide-body airliner produced by Boeing Commercial Airplanes, an advanced variant of the initial Boeing 747.The "Advanced Series 300" was announced at the September 1984 Farnborough Airshow, targeting a 10% cost reduction with more efficient engines and 1,000 nmi (1,850 km) more range. A lower deck ("belly") side door allows loading of unit load devices (ULD) up to 163 cm in height.
The flight test airplane was later refurbished, repainted in standard QANTAS livery, and registered as VH-OEE. The project was launched in 2004 with conversions by approved contractors such as The 747-400BDSF (BeDek Special Freighter) is another passenger-to-freighter conversion, carried out by Neither the 747-400BCF nor the 747-400BDSF has a nose cargo door; freight can only be loaded through the side cargo door. On December 15, 1989, Wide-body airliner, improved production series of the 747Schofield, Adriean, et al., Jumbos bow out, Aviation Week and Space Technology, September 15, 2014, pp. The model's first flight was on May 4, 1993, and entered service with The 747-400F has a main deck nose door and a mechanized cargo handling system. 44-46Adrian Schofield, Madhu Unnikrishnan and Sean Broderick. " The main appeal of the 747-400 like its predecessors was its range rather than its capacity, and in most cases it has been replaced by wide-body twin-engine aircraft of similar range, such as the For example, Delta Air Lines reduced the number of flights it operated from the United States to Moreover, economic weakness in air cargo markets has slowed demand for cargo conversions.
The 747-400F has a maximum takeoff weight of 875,000 pounds (396,890 kg) and a maximum payload of 274,100 pounds (124,330 kg).
As most 747-400s are now more than 20 years old, airlines are beginning to replace them. These allow for extra seating at the rear of the upper deck, where a galley would normally be situated on longer flights. Boeing delivered 126 Boeing 747-400F aircraft with no unfilled orders as of November 2009A 2008 747-400F value new was $101 million, a 2003 aircraft was leased $400,000 per month in 2019 for a $29 million value while a B747-400BCF was priced at around $10 million.The 747-400M (a passenger/freight or "Combi" variant) first flew on June 30, 1989, and entered service with The 747-400D (Domestic) is a high-density seating model developed for short-haul, high-volume domestic Japanese flights.
While using the updated systems and wing design of the passenger versions, it features the original short upper deck found on the classic 747s to reduce weight. This model is capable of seating a maximum of 568 passengers in a two-class configuration or 660 passengers in a single-class configuration.The -400D lacks the wingtip extensions and winglets included on other variants.
