What You'll Learn
A Boeing 747 burns 1 gallon of fuel every second
A Boeing 747, also known as the “Queen of the Skies”, is a popular choice for long routes due to its large capacity, long range, and large fuel tank. The 747 burns approximately 1 gallon of fuel per second, which amounts to 3,600 gallons per hour or 60 gallons per minute. During a 5-hour flight, a 747 will burn 18,000 gallons of fuel.
The fuel consumption of a 747 varies depending on the model and configuration. For example, the 747-400F consumes approximately 5 gallons of fuel per mile, while the 747-100 has a lower fuel capacity of 48,400 gallons. Newer models like the 747-400 have increased fuel capacity, holding up to 57,285 gallons. On average, a 747 can carry between 48,400 to 63,034 gallons of fuel, with some sources stating a more specific range of 52,410 to 57,285 gallons.
The high fuel efficiency of the 747 becomes evident when considering the number of passengers it can carry. At maximum capacity, a 747 can carry 568 passengers. Even if only 500 seats are sold, the plane is still more fuel-efficient per person than a car. For every mile travelled, each passenger on a full 747 only consumes 0.01 gallons of fuel.
The cost to refuel a 747 can range from $140,000 to $170,000, depending on factors such as fuel market price, route, model, fuel type, and taxes. The fuel efficiency of the 747 contributes to its overall efficiency, making it a preferred choice for airlines despite the high refueling costs.
With sustainability and climate change concerns, the 747's fuel consumption and resulting CO2 emissions have come under scrutiny. While the 747 is not considered the most fuel-efficient aircraft, its ability to carry a large number of passengers over long distances makes it a viable option for airlines.

A 747 can carry 48,400 to 63,034 gallons of fuel
The Boeing 747 is a fuel-guzzling aircraft, burning approximately one gallon of fuel per second. Over a 10-hour flight, a 747 may burn through 36,000 gallons of fuel, and during a five-hour flight, it can burn 18,000 gallons. This works out to five gallons of fuel per mile.
The 747 can carry a substantial amount of fuel, with sources stating a range of 48,400 to 63,000 gallons. This equates to 365,000 to 400,000 lbs, which is nearly as much as the weight of the empty plane. The exact amount of fuel carried depends on several factors, including the presence of an extra tank and the number of optional body tanks installed.
The amount of usable fuel in a 747 is the fuel that can be pumped into the engines during flight. There is also unusable fuel, which is residual fuel at the bottom of the tank that cannot be pumped out but can be drained. This unusable fuel is not accounted for as available fuel and is considered part of the plane's empty operating weight.
The 747's fuel capacity is impressive, and while the aircraft is being phased out in favor of more efficient models, it remains a significant player in the cargo market due to its large capacity.

Fuel costs: $140,000 to $170,000 to refuel a 747
Fuel is one of the highest costs for airlines, accounting for 20-40% of expenditure, and it is a cost that airlines have very little control over. The price of jet fuel has been increasing in recent years, and it is subject to fluctuations within the market influenced by global politics.
A Boeing 747 burns approximately 1 gallon of fuel every second, which amounts to 18,000 gallons in a 5-hour flight. Over a 10-hour flight, this figure can reach 36,000 gallons. This means that the cost of refuelling a 747 depends on a variety of factors, such as the length of the sector, taxi time, cargo weight, weather, direction of travel, and the price of jet fuel at the time.
For example, the jet stream in the North Atlantic can push aircraft to nearly the speed of sound, reducing fuel costs for flights travelling eastward. On the other hand, some airlines choose to fill up with enough fuel for 1.5 trips and refuel on the return journey, which may be cheaper depending on the airport.
Given the variability in fuel prices and the number of factors that influence the amount of fuel required for a flight, the cost of refuelling a 747 can vary significantly, ranging from $140,000 to $170,000.

A 747 burns 5 gallons of fuel per mile
A Boeing 747 is a large aircraft with a large fuel capacity to cover long distances. The 747 burns approximately 5 gallons of fuel per mile, or 1 gallon every second. This amounts to 18,000 gallons of fuel burned during a 5-hour flight. The exact fuel consumption depends on various factors, such as the aircraft's empty weight, payload, engine efficiency, flight path, and weather conditions.
The 747's fuel efficiency can be analyzed in different ways. On the one hand, when considering the entire aircraft, the 747 may not seem very fuel-efficient compared to other aircraft. However, when considering the number of passengers it can carry, the 747 becomes more efficient. With a maximum capacity of 568 passengers, the 747 is burning 0.01 gallons per person per mile, resulting in 100 miles per gallon per person.
The fuel efficiency of the 747 has been a topic of discussion, with some arguing that it is not as fuel-efficient as other aircraft. This has led to airlines favoring more fuel-efficient twinjet widebody aircraft. Additionally, the high cost of refueling a 747, ranging from $140,000 to $170,000, is a significant factor. However, the 747's efficiency has also been defended, with its large fuel capacity enabling it to cover long routes.
The 747's fuel capacity varies among models, ranging from 48,400 to 63,034 gallons. The earlier models, such as the 747-100, had a lower fuel capacity of 48,400 gallons, while later models like the 747-400 have increased capacity, reaching 57,285 gallons. The 747-400 burns around 10-11 tons of jet fuel per hour, which is about 22,000-24,000 pounds.
In summary, the Boeing 747 burns 5 gallons of fuel per mile, with a fuel capacity of up to 63,000 gallons. While the 747 may not be the most fuel-efficient aircraft per mile, its efficiency improves when considering its high passenger capacity. The high fuel capacity enables it to cover long routes, making it a suitable choice for airlines operating long-distance flights.

A 747 is more fuel-efficient per person than a car
The fuel efficiency of a vehicle is increased by better aerodynamics, reduced weight, improved engine brake-specific fuel consumption, and propulsive efficiency or thrust-specific fuel consumption. The Boeing 747 is one of the most popular long-haul aircraft, with a maximum capacity of 568 passengers. It burns approximately one gallon of fuel per second, which is about 14,400 litres per hour. This amounts to 18,000 gallons of fuel for a five-hour flight and 36,000 gallons for a ten-hour flight.
The fuel efficiency of a 747 is about 100 miles per gallon per person. In comparison, a typical car gets about 25 miles per gallon. A car with two passengers travelling from New York City to Los Angeles, a distance of 2,797 miles, would consume 112 gallons of gas, or 56 gallons per person. This is significantly less fuel-efficient per person than a 747.
The fuel efficiency of a 747 is further improved when it is fully occupied, which is often the case. In contrast, cars are usually occupied by fewer people, with an average of two passengers per car in the United States. Additionally, planes take a more direct path compared to cars, which may take various turns along their route.
However, it is important to consider that the comparison between a 747 and a car is not always straightforward. The fuel efficiency of a 747 can be impacted by the distance travelled, as longer non-stop flights require more fuel due to the weight of the additional fuel. This can result in a reduction in the number of available seats. On the other hand, the fuel efficiency of a car can be influenced by factors such as the type of car and the length of the trip.
In conclusion, when considering fuel efficiency per person, a 747 is generally more fuel-efficient than a car, especially when the 747 is fully occupied and travelling over long distances. However, it is important to acknowledge that the comparison between the two modes of transportation can be complex and dependent on various factors.
