The Boeing 747 is a remarkable feat of engineering, and its fuel capacity is a key factor in keeping this giant in the sky. The amount of fuel a Boeing 747 can hold depends on the model and type of fuel used. On average, a Boeing 747 can hold 48,400 to 63,636 gallons of fuel, equivalent to about 180 to 240 tonnes of fuel. The debut version, the 747-100, released in 1969, holds 48,400 gallons of jet fuel. The 747-400, a popular choice among airlines, has a 9% increased fuel capacity of 57,285 gallons. The 747 burns approximately 5 gallons of fuel per mile, or 3,600 gallons per hour, and costs around $50,000 to $200,000 to refuel.

What You'll Learn
The Boeing 747's fuel capacity varies among models
The Boeing 747 is one of the most recognizable aircraft in the world. Its high passenger capacity and long range have enabled airlines to open new routes worldwide. The amount of fuel a Boeing 747 can carry depends on the model.
The debut version, the 747-100, could carry 48,400 gallons of fuel (approximately 183,214 liters). With each new iteration, Boeing has increased the fuel capacity, allowing the 747 to cover longer distances. The 747-400F, for example, has a maximum fuel capacity of 216,846 L (57,284 gallons). This model has four main fuel tanks in the wings, a tail plane tank, a center wing tank, and reserve fuel tanks in the outer wing sections.
The final 747 model, the 747-8, was the longest commercial aircraft produced when it arrived. Boeing built two types: the 747-8i Intercontinental, which can carry 63,034 gallons (238,610 liters), and the 747-8F freighter, with a fuel capacity of 59,734 gallons (226,095 liters).
The four engines of the Boeing 747 burn around 1 gallon (approximately 4 liters) of fuel per second when cruising at altitude, translating to about 10 to 11 tons (3,500 gallons) of fuel per hour. Takeoff is the most fuel-intensive aspect of each flight, with the aircraft burning up to 5,000 gallons (about 19,000 liters) during the process.

The 747-400's fuel capacity is 9% more than its predecessors
The Boeing 747, also known as the "'Queen of the Skies', is a long-range wide-body airliner that was designed and manufactured by Boeing Commercial Airplanes in the United States from 1968 to 2023. The 747's fuel capacity varies among models and configurations. The debut version, the 747-100, which first flew in 1969, could carry 48,400 gallons of fuel. The next two versions, the 747-200 and 300, featured incremental upgrades and a slightly increased fuel capacity of 52,410 gallons.
The 747-400 is a popular choice among airlines due to its improved range, capacity, and fuel efficiency. It offers a 9% increase in fuel capacity compared to its predecessors, allowing it to hold 57,285 gallons of fuel. This increase in fuel capacity has enabled the 747-400 to have a longer range, allowing airlines to bypass traditional fuel stops.
The 747-400's fuel efficiency is also notable. At maximum seat capacity, it consumes 0.01 gallons of fuel per passenger per mile. While the 747 is not considered the most fuel-efficient aircraft, its efficiency improves with a higher passenger load. With a full passenger load of around 568 people, the 747 becomes more fuel-efficient per person than a car.
The 747-400's fuel system includes tail fuel tanks and fuel tanks in both wings, with two main fuel tanks and a reserve tank in each wing. The wing tanks are filled first, followed by the central wing tank, which holds any remaining fuel required for the specific route. This design ensures balance and symmetrical fuel delivery to the engines, contributing to the aircraft's overall efficiency.
The 747-400 has been a popular aircraft choice for airlines such as Atlas Air and Kalitta Air, and it played a significant role in the air freight market, particularly for the transport of time-sensitive goods.

The 747 burns 3,600 gallons of fuel per hour
The Boeing 747 is a remarkable feat of engineering, and its fuel capacity is a crucial factor in determining its range, efficiency, and overall operational costs. The 747 burns approximately 3,600 gallons of fuel per hour, or about 1 gallon of fuel every second. This amounts to around 18,000 gallons of fuel burned during a 5-hour flight.
The fuel capacity of the 747 varies depending on the specific model and the type of fuel it uses. On average, it can hold between 48,400 and 63,636 gallons of fuel, which is equivalent to about 180 to 213 tonnes of fuel. The fuel efficiency of the 747 is also impressive, achieving 100 miles per gallon for every passenger when fully loaded with 568 passengers.
The cost of fueling a 747 can range from $50,000 to $200,000, depending on fuel prices, which can significantly impact airline operating costs. Boeing has continuously improved the 747 over various model series, increasing the maximum takeoff weight and allowing the plane to carry more fuel and extend its range.
The 747's fuel efficiency can be compared to that of a car. While a typical car gets about 25 miles per gallon, it would need to travel more than three-quarters of a million miles to burn the same amount of fuel as a 747 burns in a 5-hour flight. Aviation fuel is typically kerosene-based, which has a higher flash point and provides more power than gasoline.
The 747's fuel load must be carefully balanced by airlines and engineers to ensure safe takeoffs, optimal performance, and efficient travel. With advancements in technology, we may see more efficient ways to power these aircraft, reducing costs and environmental impact.

The 747's four engines burn 1 gallon of fuel every second
The Boeing 747 is one of the world's most recognisable aircraft, with a long range and high passenger capacity. The 747 has four engines, which burn approximately 1 gallon (around 4 litres) of fuel per second. This equates to 10-11 tonnes (3,500 gallons) of fuel per hour when cruising at altitude.
Takeoff is the most fuel-intensive part of a flight, with the plane burning up to 5,000 gallons (19,000 litres) during this process. The 747 can carry a maximum of 57,285 gallons (216,840 litres) of fuel, although this varies between models. For example, the 747-100 can carry 48,400 gallons (183,214 litres), while the 747-8i Intercontinental has a capacity of 63,034 gallons (238,610 litres).
Despite the high fuel consumption, the efficiency of the 747 is impressive when considered in terms of passenger miles per gallon. A 10-hour flight might burn 36,000 gallons (150,000 litres) of fuel, but with 500 passengers on board, this equates to 100 miles per gallon per passenger. This is far more efficient than the average car, which gets about 25 miles per gallon.
The 747's fuel efficiency is further improved by the placement of its fuel tanks. The majority of the fuel is stored in the wings, which allows the plane to remain balanced as the fuel is funnelled symmetrically into the engines. This also increases the storage capacity in the fuselage for cargo.

The 747's fuel tanks are in the wings and fuselage
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 has been in production since 1967, with over 100 customers purchasing 1,574 examples, logging more than 118 million flight hours.
The 747's fuel tanks are located in its wings and fuselage. The wings of the 747 are so large that they can accommodate huge fuel tanks that take up the entire wing span 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. This allows the plane to remain balanced as the fuel funnels down into the engines symmetrically, increasing the storage capacity in the fuselage for cargo.
The exact fuel capacity varies between models, with some models containing additional fuel tanks in the tail. The debut version, the 747-100, had a fuel capacity of 48,400 gallons (approximately 183,214 litres). The 747-400F model has a maximum fuel capacity of 216,846 litres (57,284 gallons), while the 747-8i Intercontinental can carry 63,034 gallons (238,610 litres).
The four engines of the 747 burn around 1 gallon (approximately 4 litres) of fuel every second when cruising at altitude, which equates to about 10 to 11 tonnes (3,500 gallons) of fuel per hour. Takeoff is the most fuel-intensive aspect of each flight, with the aircraft burning up to 5,000 gallons (about 19,000 litres) during the process.
