The Boeing 747 is one of the world's most recognisable aircraft, with its high passenger capacity and long range enabling airlines to open new routes worldwide. The 747's fuel tanks are so large that they take up the entire wingspan of the plane. The majority of the fuel is stored in the wings, with two main fuel tanks in each wing, reserve fuel tanks in the outer wing sections, and a central wing tank in the middle. The amount of fuel the 747 can carry depends on the aircraft model, with the debut version, the 747-100, capable of carrying 48,400 gallons of fuel, and the 747-8i Intercontinental carrying 63,034 gallons.

The Boeing 747's fuel tank takes up the entire wing span
The Boeing 747 is an iconic aircraft with an impressive range and high passenger capacity. Affectionately known as the "Queen of the Skies", it has been in service since 1967 and has enabled airlines to open up new, previously unserved direct routes worldwide. The 747 has an extensive fuel capacity, allowing it to operate on long-haul routes. The fuel tanks on a 747 are indeed large and strategically positioned within the aircraft's wings, taking up the entire wing span.
The wings of the 747 are designed to accommodate multiple fuel tanks, including the main fuel tanks, reserve fuel tanks, and, in some variants, a central wing tank. The use of the wings as fuel storage is a common design feature in aircraft, from light single-engine piston planes to large jets like the 747. This design choice takes advantage of the natural empty spaces within the wings, which are ideal for storing large volumes of fuel. By utilising the wings, the aircraft's body has more space for cargo and passengers, improving efficiency.
The Boeing 747-400, a popular variant, has eight fuel tanks in total, with a combined capacity of 57,164 gallons of Jet-A fuel, weighing over 380,000 pounds. This amount of fuel significantly influences the aircraft's performance, and proper fuel management is crucial to maintaining balance during long flights. The distribution of fuel among the tanks is automated, but the crew must also perform specific tasks to ensure stable flight.
The exact fuel capacity of the 747 varies across different models and configurations. For example, the debut version, the 747-100, could carry 48,400 gallons of fuel. Subsequent models, such as the 747-200 and 747-300, increased the fuel capacity to 52,410 gallons. The 747-8 Intercontinental, the passenger version of Boeing's largest jumbo jet, has a maximum fuel capacity of 63,034 gallons, though a problem with the tail tanks initially prevented their use, reducing the range.
In summary, the Boeing 747's fuel tanks are strategically designed to utilise the entire wing span, maximising fuel storage while maintaining the aircraft's balance and performance. The large fuel capacity of the 747 has been a key factor in its success as a long-haul aircraft, enabling it to serve long-range routes with high passenger capacities efficiently.

The 747-400 has eight fuel tanks with a capacity of 57,164 gallons
The Boeing 747 is one of the world's most recognisable aircraft, with a long range and high passenger capacity. The amount of fuel a 747 can carry depends on the model. The debut version, the 747-100, could carry 48,400 gallons of fuel. The 747-200 and 300 models had a slightly increased capacity of 52,410 gallons.
The 747-400's successor, the 747-8, has a capacity of 63,055 gallons. However, a problem discovered during testing means that the fuel tanks in the horizontal stabilisers cannot be used, reducing the range by 300 to 400 miles. The freighter version of the 747-8 does not use the tail tanks, as customers prefer greater hauling capacity over extended range.

The 747-8 Intercontinental can carry 63,034 gallons
The Boeing 747 is one of the world's most recognisable aircraft, with its high passenger capacity and long range allowing airlines to open new routes worldwide. The 747's fuel system is an important component of its functionality, with the fuel tanks typically taking up the entire wingspan of the plane.
Different models of the 747 have varying fuel capacities. The debut version, the 747-100, could carry 48,400 gallons of fuel. The subsequent models, the 747-200 and 300, had a slightly increased fuel capacity of 52,410 gallons. The 747-400, the most popular member of the 747 family, could hold 57,285 gallons of fuel.
The 747-8 is the latest variant of the 747, featuring a 16% increase in payload capacity. There are two versions of the 747-8: the 747-8i Intercontinental and the 747-8f freighter. The 747-8i Intercontinental can carry 63,034 gallons of fuel, weighing approximately 400,000 pounds, which is nearly as much as the empty plane itself. This amount of fuel is crucial for the aircraft's long-range capabilities, allowing it to operate on some of the world's longest routes.
The 747-8i Intercontinental's fuel capacity is impressive, but it is important to note that airliners often fly with less than full tanks. The distribution of fuel among the tanks also affects the aircraft's performance, and fuel management is a critical aspect of operating the 747.
In summary, the 747-8 Intercontinental's fuel capacity of 63,034 gallons showcases its long-range capabilities and contributes to its status as one of the world's most renowned aircraft.

The 747-8F freighter has a capacity of 59,734 gallons
The Boeing 747 is a large aircraft that has been in service since the 1970s. The 747-8F freighter is a more modern variant, with a maiden flight taking place on February 8, 2010. This freighter version has a fuel capacity of 59,734 gallons.
The 747-8F freighter is a highly capable aircraft, with a maximum payload capacity of 154 short tons (140 tonnes) of cargo. It can carry seven more standard air cargo containers than its predecessor. The freighter can haul 308,000 pounds (140 tonnes) over 4,120 nautical miles, demonstrating its impressive performance.
The 747-8F's fuel capacity contributes to its efficiency and range. The aircraft's fuselage is 18 feet longer than its predecessors, reaching a total length of 250 feet. This extra length allows for greater fuel capacity, with the redesigned wing accommodating more fuel and eliminating the need for additional tanks in the horizontal tail.
The 747-8F freighter's fuel capacity is a significant improvement over earlier models, such as the 747-400, which has a fuel capacity of 57,164 gallons. The increased fuel capacity of the 747-8F enhances its performance and range, making it a preferred choice for cargo operations.
The demand for the 747-8F freighter is high, particularly due to its large capacity. It has no direct competitor, as Airbus' competing A380 freighter version was cancelled during development. The 747-8F's efficiency and range, enabled by its fuel capacity, make it a popular choice for airlines and cargo operations.

The 747-100 can carry 48,400 gallons
The Boeing 747 is a large aircraft with varying fuel capacities across its models. The 747-100, the first model of the 747, was launched in 1969 and can carry 48,400 gallons of jet fuel. This initial model was followed by the 747-100B, a higher maximum takeoff weight (MTOW) variant, and the 747-100SR, a short-range version with greater payload capability and lower fuel capacity.
The 747-100B has an increased fuel capacity of 48,070 gallons, allowing for a range of 5,000 nautical miles with a typical 452-passenger payload. This model first flew in June 1979 and received FAA certification the following month. The 747-100B offered improved engines compared to the original -100, and the last of these models was retired by Iran Air in 2014.
The 747-100's fuel capacity of 48,400 gallons is impressive, and while it offered sufficient payload and range for medium-haul operations, demand for longer-range aircraft led to the development of the improved -200 model. The 747-200 featured more powerful engines, increased MTOW, and greater range, with a fuel capacity of 52,410 gallons.
The fuel capacity of the 747-100 at 48,400 gallons showcases the aircraft's ability to carry a substantial volume of fuel, contributing to its performance and range capabilities.
