The Boeing 747 is a remarkable feat of engineering, with a fuel capacity of around 63,000 gallons (238,610 litres) weighing nearly 400,000 lbs, which is almost as much as the plane itself when empty. The debut version, the 747-100, had a capacity of 48,400 gallons (183,214 litres), and the 747-400 increased this by more than 9% to 57,285 gallons (216,840 litres). The latest model, the 747-8, has a capacity of 63,034 gallons (238,610 litres). The fuel capacity of the 747 has played a pivotal role in enabling the aircraft to cover longer distances, and the plane continues to fly on some of the longest routes globally.

What You'll Learn
The fuel capacity of a Boeing 747 is 63,000 gallons
The Boeing 747 has two main fuel tanks in each wing, reserve fuel tanks in the outer wing sections, and a central wing tank in the middle. The wing tanks are filled first for structural reasons, and then any remaining fuel needed for the specific flight is added to the central wing tank. Select models of the jumbo jet can also utilise the horizontal stabilizer as an auxiliary fuel tank to increase total capacity.
The four engines of the Boeing 747 burn approximately 1 gallon, or roughly 4 litres, of fuel every second while cruising. This equates to about 10 to 11 tonnes, or 3,500 gallons, of fuel burned every hour. Despite these large numbers, the efficiency of the aircraft is impressive, with a flight carrying 500 people resulting in 100 miles to the gallon for each passenger.
The debut version of the Boeing 747, the 747-100, could carry 48,400 gallons of fuel. Boeing has continuously improved the 747 over various model series, and with each new iteration, the fuel capacity has also increased. The Boeing 747-400, for example, increased fuel capacity by more than 9% to 57,285 gallons. The final 747 model, the 747-8, had a further 16% increase in payload capacity, with the 747-8i Intercontinental carrying 63,034 gallons of fuel.

The plane's range is 7,790 nautical miles
The Boeing 747 is a remarkable feat of engineering, with a fuel capacity of around 63,000 gallons (or 238,604 litres) and a range of 7,790 nautical miles. This large fuel capacity is a crucial factor in determining the aircraft's range and efficiency. The debut version, the 747-100, had a fuel capacity of 48,400 gallons (approximately 183,214 litres). The Boeing 747-400 improved on this with a fuel capacity of 57,285 gallons (216,846 litres). The latest iteration, the 747-8, has a capacity of 63,034 gallons (238,610 litres).
The 747's four engines burn approximately 10 to 11 tonnes of fuel per hour when cruising, which equates to roughly 1 gallon (or 4 litres) of fuel per second. During takeoff, the plane burns about 5,000 gallons (19,000 litres), which is around 10% of its total fuel capacity. The fuel is stored in two main fuel tanks in each wing, with reserve tanks in the outer wing sections and a central wing tank in the middle.
The 747's long range has allowed airlines to open up new and previously unserved direct routes worldwide. The plane's efficiency is also notable, with a full tank/max-rated distance of 0.12 miles per gallon, and a three-class config of around 56 miles per gallon, which is more efficient than a single person travelling in a car.

It has 2 main fuel tanks in each wing
The Boeing 747 is one of the world's most recognisable aircraft, with an impressive range and high passenger capacity. The amount of fuel that a 747 can carry depends on the model. The debut version, the 747-100, could carry 48,400 gallons of fuel, or approximately 183,214 litres. The 747-400F has a maximum fuel capacity of 216,846 litres (57,284 gallons).
The 747 has two main fuel tanks in each wing, with reserve fuel tanks in the outer wing sections. There is also a central wing tank in the middle. The wing tanks are filled first for structural reasons, and then any remaining fuel needed for the flight is added to the central tank. Some models can also seal part of the horizontal stabilizer and use it as an auxiliary fuel tank to increase total capacity.
The majority of the fuel is stored in the aircraft's wings, which allows the plane to remain balanced as the fuel funnels down symmetrically into the engines. This increases the storage capacity in the fuselage for cargo.
The four engines of the 747 burn around 1 gallon (approximately 4 litres) of fuel every second, or about 10 to 11 tonnes (3,500 gallons) of fuel per hour when cruising. 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.

The 747 burns 10-11 tonnes of fuel per hour
The Boeing 747 is a remarkable feat of engineering, with a fuel capacity of around 63,000 gallons (or 238,610 litres) and a maximum gross payload of 128.5 metric tons. This large fuel capacity is a crucial factor that determines the aircraft's range and efficiency. The four engines of the 747 burn approximately 1 gallon (or 4 litres) of fuel per second when cruising at altitude, which equates to 10-11 tonnes of fuel per hour.
The 747's high fuel consumption is a result of its large size and long range. The aircraft's debut version, the 747-100, had a fuel capacity of 48,400 gallons, and subsequent models have seen increases in fuel capacity, with the 747-400 featuring a 9% increase to 57,285 gallons. The latest model, the 747-8, has a fuel capacity of 63,034 gallons.
The majority of the 747's fuel is stored in the aircraft's wings, with two main fuel tanks in each wing and reserve fuel tanks in the outer wing sections. This allows the plane to remain balanced as the fuel funnels down into the engines symmetrically, increasing storage capacity in the fuselage for cargo or passengers. Select models of the 747 also use part of the horizontal stabilizer as an auxiliary fuel tank to further increase capacity.
The high fuel efficiency of the 747 means that it is more efficient per person than a car. On a flight carrying 500 people, the aircraft achieves 100 miles to the gallon for every passenger. However, the large fuel load of the 747 has also been a factor in several notable crashes when the fuel load was miscalculated.
The Boeing 747 has been a workhorse of the aviation industry, with over 100 customers purchasing 1,574 examples and logging more than 118 million flight hours. However, with improvements in engine efficiency and a move towards smaller, long-range aircraft, the 747 is nearing the end of its production run.

Boeing 747 production is stopping
The Boeing 747, also known as the "Queen of the Skies", is a wide-body, long-range airliner that has been in production since 1967. With its four wing-mounted engines, it can carry approximately 63,000 gallons of fuel, weighing around 400,000 pounds. This is almost as much as the weight of the empty plane itself.
The 747 has been a game-changer for global travel, allowing airlines to introduce new direct routes worldwide. However, its production is coming to an end. In January 2016, Boeing announced a reduction in the production rate of the 747-8 model, and the final 747 aircraft rolled off the production line on December 6, 2022. The last Boeing 747 was delivered to Atlas Air in early 2023, marking the end of an era for this iconic aircraft.
The decision to halt production can be attributed to several factors. Firstly, the 747's efficiency is being challenged by newer aircraft. While the 747 is still relevant in the cargo market due to its large capacity, the availability of long-range mid-size planes has reduced the need for huge planes that connect major hubs. Additionally, advancements in engine technology have made modern aircraft more reliable with fewer engines, eliminating the necessity of a quad-engine plane like the 747.
The end of 747 production is an emotional moment for those involved in its creation and operation. Kim Smith, Boeing Vice President and General Manager, expressed pride in the impact the 747 has had on global travel. The aircraft has spanned 54 years of production, with 1,574 airplanes built and over 118 million flight hours logged.
Despite the end of production, the 747 will continue to fly across the globe for years to come, leaving its mark on the history of aerospace and revolutionizing long-range travel.
