Background

Following its introduction in 1970, the Boeing 747 became a major success with airlines and the flying public. As the world's first wide-body jetliner, the 747 had revolutionized air travel, and cemented its manufacturer's dominance in the passenger aircraft market. In 1980, Boeing announced the 747-300, its latest 747 variant featuring greater passenger capacity. This was made possible by making a stretched upper deck (SUD), previously an option on the 747-200, a standard feature. The SUD was almost twice as long as the original 747 upper deck. However, besides increased capacity, the 747-300 did not offer any increase in range, nor did it include improvements in flight deck technology or construction materials. At the same time, 747s were becoming more costly to operate due to a number of factors, notably antiquated flight control systems, three-person flight crews, and fuel costs.

In 1982, Boeing introduced a two-crew glass cockpit, new engines, and advanced materials on its 757 and 767 twinjets. Similar technologies were also included in the design plans for newly-announced rival wide-body aircraft, namely the Airbus A340

. At the same time, combined sales of the 747-100, −200, and −300 models (collectively referred to as the 747 "Classics") neared 700, but new orders slowed precipitously. The introduction of the 747-300 did little to stem the decline, and itself faced potential competition from more modern designs. As a result, Boeing began considering a more significant upgrade for its largest passenger jet.

By early 1984, company officials had identified five development objectives for the latest 747 upgrade: new technologies, an enhanced interior, a 1000 nautical miles (1,852 km) range increase, more efficient engines, and a 10 percent reduction in operating cost. In September 1984, Boeing announced development of the newest 747 derivative, the "Advanced Series 300", at the Farnborough Airshow. On October 22, 1985, the type was officially launched when Northwest Airlines became the first 747-400 customer, with an order for 10 aircraft. Cathay Pacific

Design effort

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. While the aircraft was planned as a new-technology upgrade, Boeing originally proposed minimal design changes in order to reduce development cost and retain commonality

 with existing models. However, the airline consultative group pushed for more aggressive changes, most notably in moving to a two-crew glass cockpit. As a result of airline input, the 747-400's new digital cockpit design featured a hybrid of the cathode-ray tube (CRT) display technologies first employed on the 757 and 767, along with carry-over 747 systems such as its autopilot

The 747-400's wingspan was stretched by 17 feet (5.2 m) over the Classic 747 through wingtip extensions. For reduced aerodynamic drag, the wings were fitted with 6 feet (1.8 m)-tall winglet

s. Despite the added length, the wings were 6000 lbs lighter as a result of new aluminum alloys. The horizontal tail was also redesigned to fit a 3300 gal fuel tank, resulting in a 350 nautical miles (648.2 km) range increase, and the rudder travel was increased to 30 degrees. The landing gear was redesigned with larger wheels and carbon brakes.

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. A primary reason for the delays was the unprecedented complexity of interior configurations offered to airlines, which ranged from lavatory and galley locations to the color shades of cabin warning labels

. Coupled with new, relatively inexperienced workers, a lack of veteran technicians, interior configurations needing costly re-work, and teething problems with electronics integration on the advanced flight deck, 747-400 production fell behind schedule. However, the company managed to resolve early production issues by mid-1989, with all three 747-400 engine variants delivered within four months of each other, and overall delays not exceeding several weeks.

While the manufacturer asserted that the 747-400's cabin floor was no different than the already-certified and in-service 747-300, the JAA maintained that the newer model would have a service life into 2020 and beyond and was thus subject to a newer, more stringent standard which had been updated to reflect the risk of explosive device

After the first 747-400 deliveries, Boeing began production on additional variants of the aircraft. The first 747-400 Combi, able to carry both passengers and freight, was rolled out in June 1989.

. The −400F can be easily distinguished from the passenger −400 by its shorter upper-deck hump.

The 747-400F has a main deck nose door and a mechanized cargo handling system. The nose door swings up so that pallets or containers up to 40 ft (12 m) can be loaded straight in on motor-driven rollers. An optional main deck side cargo door (like the 747-400M (Combi)) allows loading of dimensionally taller cargo modules. Boeing delivered 126 Boeing 747-400F aircraft with no unfilled orders as of November 2009. The last −400F was delivered to Nippon Cargo Airlines

747-400M

The 747-400M (a passenger/freight or "Combi" variant) first flew on June 30, 1989 and entered service with KLM on September 12, 1989. Based on the successful Combi versions of the Classic 747s, the −400M has a large cargo door fitted to the rear of the fuselage for freight loading to the aft main deck cargo hold. A locked partition separates the cargo area from the forward passenger cabin, and the −400M also features additional fire protection, a strengthened main deck floor, a roller-conveyor system, and passenger-to-cargo conversion equipment. The last 747-400M was delivered to KLM on April 10, 2002.

747-400D

The 747-400D (Domestic) is a high density seating model developed for short-haul domestic Japanese flights. The aircraft is capable of seating a maximum of 568 passengers in a 2-class configuration or 660 passengers in a single-class configuration.

The −400D lacks the wing tip extensions and winglets included on other variants. The benefits of winglets would be minimal on short routes. The −400D may be converted to the long range version when needed. The 747-400D is also unusual in having more windows on both sides of the upper deck than the basic −400 series. This allows for additional seating all the way down the upper deck, where a galley is situated on most international models. In total, 19 of the type were built, and the last was delivered to All Nippon Airways in December 1995.

747-400ER

The 747-400ER (Extended Range) was launched on November 28, 2000 following an order by Qantas for six aircraft. This was ultimately the only order for the passenger version. The −400ER can fly an additional 500 miles (805 km) or carry 15,000 lb (6,800 kg) more freight. Qantas received the first −400ER on October 31, 2002. The 747-400ER included the option of one or two additional 3,240 US gallon body fuel tanks in the forward cargo hold. Manufactured by Marshall Aerospace

, these tanks utilized metal to metal honeycomb-bonded technology to achieve a high dry weight-to-fuel volume ratio. Similar technology has been used in the development by Marshall of body fuel tanks for the 777-200LR and P-8A Poseidon.

747-400ERF

The 747-400ERF (747-400ER Freighter) is the freight version of the −400ER, launched on April 30, 2001. The 747-400ERF is similar to the 747-400F, except for increased gross weight capability which allows it to carry more cargo weight. Unlike the 747-400F, the type is not fitted with the cargo compartment fuel tanks. The 747-400ERF has a maximum takeoff weight of 910,000 pounds (412,769 kg) and a maximum payload of 248,600 pounds (112,760 kg). It offers the cargo airline the choice of either adding 22,000 pounds (9,980 kg) more payload than other 747-400 freighters, or adding 525 nautical miles (972.3 km) to the maximum range.

The type has a maximum range of 5,700 miles (9,200 km), about 326 miles (525 km) farther than other 747-400 freighters, and has a strengthened fuselage, landing gear and parts of its wing, along with new, larger tires. The first −400ERF was delivered to Air France

747-400 Converted Freighter

The 747-400BCF (Boeing Converted Freighter), formerly known as the 747-400SF (Special Freighter), is a conversion program for standard passenger 747-400s. The project was launched in 2004 and will be done by approved contractors such as TAECO, KAL Aerospace and SIA Engineering. The first Boeing 747-400BCF was redelivered to Cathay Pacific
