The Boeing 747's fuel capacity of around 63,000 gallons translates to an impressive weight of nearly 400,000 pounds. This weight is almost equivalent to the weight of the empty plane itself. The majority of this fuel is stored in the aircraft's wings, which helps maintain symmetry in fuel delivery to the engines and maximizes storage capacity in the fuselage for cargo and passengers. The placement of fuel in the wings also minimizes the bending moment, reducing the overall weight of the aircraft's structure.
The Boeing 747's fuel burn rate is approximately one gallon, or about four litres, per second. This equates to around 3,500 to 3,800 gallons of fuel burned per hour at cruising speed. The actual burn rate depends on various factors, including passenger capacity, engine type, speed, and aircraft weight. Takeoff is the most fuel-intensive part of a flight, with the 747 consuming up to 5,000 gallons during this critical phase.
The fuel efficiency of the Boeing 747 has been a subject of debate. When compared to a car on a per-passenger basis, the 747 can be more efficient. For example, on a flight from New York to Los Angeles with 200 passengers, the 747 would consume approximately 27 gallons per person, while a car with two passengers for the same route would use 56 gallons per person. However, when considering the overall efficiency of the aircraft, the 747 may not perform as well, with a fuel economy of around 0.12 to 0.18 miles per gallon.
The Boeing 747's remarkable fuel capacity enables it to undertake long-haul international flights. With a full tank, the 747-8i variant can achieve a range of 8,000 miles or more.

The plane has four engines that burn through a lot of fuel—approximately one gallon, or about four litres, every second. This equates to about 3,500 to 3,800 gallons of fuel per hour when cruising at altitude. The 747 burns approximately 5 gallons of fuel per mile (or 12 litres of fuel per kilometre).
The 747 has a maximum fuel capacity of around 63,000 gallons, which weighs about 400,000 lbs. This is nearly as much as the plane itself when empty. 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 design helps to balance the plane and increase storage capacity in the fuselage for cargo and passengers.
The exact fuel capacity and burn rate can vary between different models of the 747. For example, the 747-200 and 300 have a fuel capacity of 52,410 gallons, while the 747-400 can hold 57,285 gallons. The latest passenger version, the 747-8i, can carry 63,034 gallons, and the cargo version, the 747-8f, can hold 59,734 gallons.
Despite the high fuel consumption, the 747 is actually quite fuel-efficient when you consider the number of passengers it can carry. A full plane with 500 passengers would be burning 0.01 gallons per person per mile, resulting in 100 miles per gallon per person.
