Boeing 747 8

The Airbus A737 500 is a passenger airplane manufactured in France. It came out in
2006, though there were early deliveries in 2002. It is designed for 372 passengers
in a single-class seat arrangement and 313 in a double class system. The travel
range of this plane is 9,018 nautical miles or 16,700 kilometers. A single unit of the
plane costs around $233 million. When it was first introduced, it was billed as the
passenger airplane with the longest range. It is powered by four 53,000 lbf thrust
Rolls Royce Trent 553 turbofans and uses the Honeywell 331-600 (A) APU. It is one
of the airplanes of choice of Emirates, which has 10 units of this model. Airbus has
sold 22 units of this model.

The Boeing 747 400 is a passenger plane made in the United States that can
accommodate 624 passengers in a single-class set up and 524 in a two-class
system. It has a travel range of 7,260 nautical miles or 13,446 kilometers. It has four
General Electric GE CF6-80C2B5F engines at 62,100 lbf to provide its power. The
maximum cruising speed is 565.47 miles per hour and the service ceiling is 45,000
feet. The plane costs $228 million. Boeing has already sold 1,358 units of this model.

The Boeing 747 is an American wide-body commercial jet airliner and cargo aircraft, often referred to by its original nickname, Jumbo Jet, or Queen of the Skies. Its distinctive "hump" upper deck along the forward part of the aircraft makes it among the world's most recognizable aircraft, and it was the first wide-body produced. Manufactured by Boeing's Commercial Airplane unit in the United States, the original version of the 747 had two and a half times greater capacity than the Boeing 707one of the common large commercial aircraft of the 1960s. First flown commercially in 1970, the 747 held the passenger capacity record for 37 year

The four-engine 747 uses a double deck configuration for part of its length. It is available in passenger, freighter and other versions. Boeing designed the 747's hump-like upper deck to serve as a first class lounge or extra seating, and to allow the aircraft to be easily converted to a cargo carrier by removing seats and installing a front cargo door. Boeing did so because the company expected supersonic airliners (development of which was announced in the early 1960s) to render the 747 and other subsonic airliners obsolete, while the demand for subsonic cargo aircraft would be robust well into the fut The 747 was expected to become obsolete after 400 were sold,[but it exceeded critics' expectations with production passing the 1,000 mark in 199 By May 2016, 1,521 aircraft had been built, with 22 of the 747-8 variants remaining on orde

The 747-400, the most common passenger version in service, has a high-subsonic cruise speed of Mach 0.85–0.855 (up to 570 mph or 920 km/h) with an intercontinental range of 7,260 nautical miles (8,350 mi or 13,450 kThe 747-400 passenger version can accommodate 416 passengers in a typical three-class layout, 524 passengers in a typical two-class layout, or 660 passengers in a high density one-class configuration.The newest version of the aircraft, the 747-8, is in production and received certification in 2011. Deliveries of the 747-8F freighter version to launch customer Cargolux began in October 2011; deliveries of the 747-8I passenger version to Lufthansa began in May 2012.

Airliner proposal

The 747 was conceived while air travel was increasing in the 196 The era of commercial jet transportation, led by the enormous popularity of the Boeing 707 and Douglas DC-8, had revolutionized long-distance travelEven before it lost the CX-HLS contract, Boeing was pressed by Juan Trippe, president of Pan American World Airways (Pan Am), one of their most important airline customers, to build a passenger aircraft more than twice the size of the 707. During this time, airport congestion, worsened by increasing numbers of passengers carried on relatively small aircraft, became a problem that Trippe thought could be addressed by a large new aircraf

In 1965, Joe Sutter was transferred from Boeing's 737 development team to manage the design studies for a new airliner, already assigned the model number 747Sutter initiated a design study with Pan Am and other airlines, to better understand their requirements. At the time, it was widely thought that the 747 would eventually be superseded by supersonic transport aircraft. Boeing responded by designing the 747 so that it could be adapted easily to carry freight and remain in production even if sales of the passenger version declined. In the freighter role, the clear need was to support the containerized shipping methodologies that were being widely introduced at about the same time. Standard containers are 8 ft (2.4 m) square at the front (slightly higher due to attachment points) and available in 20 and 40 ft (6.1 and 12 m) lengths. This meant that it would be possible to support a 2-wide 2-high stack of containers two or three ranks deep with a fuselage size similar to the earlier CX-HLS project.

In April 1966, Pan Am ordered 25 747-100 aircraft for US$525 million. During the ceremonial 747 contract-signing banquet in Seattle on Boeing's 50th Anniversary, Juan Trippe predicted that the 747 would be "... a great weapon for peace, competing with intercontinental missiles for mankind's destiny" As launch customer, and because of its early involvement before placing a formal order, Pan Am was able to influence the design and development of the 747 to an extent unmatched by a single airline before or since.
