The Boeing 747 is a large, wide-body (two-aisle) airliner with four wing-mounted engines. Its wings have a high sweep angle of 37.5° for a fast, efficient cruise speed of Mach 0.84 to 0.88, depending on the variant. The sweep also reduces the wingspan, allowing the 747 to use existing hangars.

Mar 5, 2024 · As the fastest wide-body airplane in the world, the Boeing 747 can take off at 160 kts (184 mph) and cruise at an astonishing 660 mph (Mach 0.86 ). Meanwhile, the 747’s setting chosen will determine the approximate speed to land—between 145 and 150 kts (166 and 172 mph). For the optimum flying characteristics, Boeing has optimized the design.

The B707 helped Boeingusher in the era of commercial jetliners and revolutionized air travel and it was the catalyst for the modern age of aviation. The B707 might’ve paved the way for the B747, but the actual groundwork for the B747 is credited to the U.S Military. In the early 1960’s the U.S Air Force needed a replacement for its aging Douglas C-...
The Boeing B747 has spawned nearly 20 variants, (not including military variants) over its 54-year production run. We can’t go over the specifications for every model. Instead, the specification table below will show the evolution of the B747 during its lifetime. We’ve chosen two of the most popular older variants and the last variant to represent ...
The Boeing 747 was unlike any other commercial jetliner when it was introduced, and even today remains only one of two passengers “jumbo jets”, the second being the Airbus A380. The size of the aircraft gave it unique characteristics that pilots deal with. The sheer size and weight of the B747 meant that even with its four engines and combined thru...
Cabin Configuration
Each Boeing 747 had three base configurations. The three-class configuration was made up of first, business, and economy classes. The two-class configuration included business and economy classes. Finally, the single-class or maximum occupancy configuration included only economy class seats. Most often, airlines deviated from the base configurations and would ask Boeing for specific configurations for their aircraft. In the early days when air travel was all about glamour, the upper deck woul...
Engine Configuration
Initially, the airlines had little choice in which engine they could choose for their B747. The only engine available was the Pratt & Whitney JT9D-7A which had been custom built for the B747. As time went on, both General Electric and Rolls-Royce signed up to provide engines for the B747. But why would airlines want to choose other engine options? Most airlines try to choose one that is the most cost-effective, reliable, and low-maintenance engine possible. But choosing an engine isn’t as bla...
An airplane named the “Queen of the Skies” comes with a hefty price tag, and throughout its 54-year production run, the B747 has always been one of the most expensive aircraft on the planet. 1. The original B747-100 was first introduced on 9th February 1970, and cost Pan Am $24 million, which when adjusted for inflation in 2022, brings the total to...
The Boeing 747 managed to bring down the cost of flying enough to make aviation accessible to the masses. However, operating a quad-engine double-decker aircraft with an MTOW of 738,000 lbs (334,750 kg) was never going to be cheap. High operational costs became the Achilles heel of the aircraft, and when twin-engine aircraft that could rival the ra...
The Boeing 747 has been around for more than 50 years and during its impressive production run has spawned more than 34 variants of both passenger and military variants combined, which is more than any other jetliner. There were supposed to be nine additional models, but these were undeveloped as the need for larger quad-engined died out. Given the...
747-100SR
This model was created by Boeing at the request of Japan Airlines, which wanted a short-range high-capacity version of the B747.
747SP
The Boeing 747 Special Performance or SP for short, was created by Boeing to compete against the Lockheed Martin L-1011 Tristar. The SP maintained the long range of the B747 but was shortened by 47 ft (14 m) shorter than the original. The small airframe meant the SP could only manage an MTOW of 700,000 ( kg), 35,000 lbs less than the original. It also had a maximum occupancy of 297 in a three-class configuration, with which it could manage a range of 5,830 nm ( km).
747-200
The second generation of the B747 entered service in 1972. It was fitted with more powerful Pratt & Whitney JT9D-7A engines, this allowed the B747-200 to fly farther and have a higher payload than the B747-100. The B747-200 also came in both convertible and combination variants.
747-SOFIA
The SP was also chosen as the basis for this Stratospheric Observatory for Infrared Astronomy (SOFIA), which is an airborne observatory built by NASA and the German Aerospace Center.
747-LCF Dreamlifter
This variant of the B747 is especially unique. The Large Cargo Freighter (LCF) has a total volume of 65,000 ft³ (1,840 m³), which is three times the storage of the base aircraft, a B747-400F. The Dreamlifter has to be this large to serve its primary purpose of ferrying parts for the B787 Dreamliner over the globe.
747 SCA
Boeing and Nasa joined forces to create two highly modified versions of the B747-100 which were capable of carrying the NASA Space Shuttle. The fuselage was fitted with anchor points where the shuttle would dock, allowing the aircraft to transport the shuttle.
The Boeing 747 didn’t truly have any competition until the Airbus A380 was introduced in 2007. By then large quad-engine jets were on their way out and Boeing knew this, which is why they didn’t create a competitor for the A380.
On February 9, 2020, a British Airways Boeing 747-400 broke the New York–London subsonic airliner speed record in 4 hours 56 minutes, pushed by the powerful Jetstream linked to Storm Ciara. [44] 747-400F [ edit ]
Apr 27, 2024 · Summary. The Boeing 747-8 has a cruising speed of Mach 0.86, making it one of the fastest commercial jets in history. While the A380 is bigger, it has a slightly lower cruising speed than the 747. The Boeing 707 and DC-8 were capable of flying at impressive speeds and outpaced older quadjets.
