The Boeing 747 is a quadjet aircraft that can carry approximately 63,000 gallons of fuel, weighing around 400,000 lbs. During a flight, the 747 burns about 1 gallon of fuel every second, which equates to 36,000 gallons over a 10-hour flight. This amounts to 5 gallons of fuel per mile or approximately 10-11 tonnes of fuel burned per hour while cruising. The fuel efficiency of the 747 is often compared to that of cars and newer aircraft, with calculations considering factors such as the number of passengers, distance travelled, and fuel consumption.

What You'll Learn
A Boeing 747 burns 1 gallon of fuel per second
A Boeing 747 burns approximately 1 gallon of fuel per second. This equates to about 4 litres per second. During a 5-hour flight, a Boeing 747 will burn 18,000 gallons of fuel. Over a 10-hour flight, this figure rises to 36,000 gallons.
The amount of fuel burned can vary depending on several factors, including the aircraft's empty weight, payload, engine efficiency, flight path, and weather conditions. For example, a Boeing 747 flying from London to New York burned approximately 70,000 kilograms of fuel.
When considering fuel efficiency, it's important to take into account the number of passengers on board. A Boeing 747 can carry up to 568 passengers. Even if only 500 seats are sold, the plane is still more fuel-efficient per person than a car. For a flight with 500 passengers, the 747 burns 0.01 gallons per person per mile, resulting in 100 miles per gallon per person.
The Boeing 747 is a quadjet aircraft, and while it has impressive fuel capacity, newer twin-engine aircraft are significantly more fuel-efficient. The retirement of the 747 by some airlines can be attributed to the development of more efficient aircraft, as well as the reduced travel demand during the COVID-19 pandemic.

It can carry 63,000 gallons of fuel
The Boeing 747 is a fuel-guzzling aircraft, burning up to one gallon of fuel every second. During a five-hour flight, this equates to 18,000 gallons of fuel. On a longer, ten-hour flight, the plane might burn through 36,000 gallons of fuel.
The Boeing 747 can carry a maximum of 63,000 gallons of fuel, which weighs approximately 400,000 lbs. This is nearly as much as the weight of the empty plane. The fuel is mostly stored in the wings, close to the centre of gravity, to minimise changes as the fuel is burned and to reduce the bending moment on the wings.
The amount of fuel burned by the Boeing 747 during flight depends on various factors, including the payload, efficiency of the engines, flight path, and weather conditions. The plane burns approximately 5 gallons of fuel per mile, or 12 litres of fuel per kilometre.
Despite the seemingly high fuel consumption, when considering the number of passengers, the fuel efficiency of the 747 becomes more apparent. The plane can carry up to 568 passengers, and when reduced to 500 passengers, the fuel burned per person per mile is significantly reduced to 0.01 gallons. This equates to 100 miles per gallon per person.
With improvements in engine efficiency, the need for large, quad-engine planes like the 747 is decreasing. However, the 747 still has a role in the cargo market, and its impressive fuel capacity contributes to its capability for long-range flights.

A 10-hour flight would burn 36,000 gallons
A Boeing 747 is a quadjet aircraft that uses approximately 1 gallon (about 4 liters) of fuel every second. This amounts to 36,000 gallons (150,000 liters) of fuel burned over a 10-hour flight. This works out to be 5 gallons of fuel per mile (12 liters of fuel per kilometer) or 0.01 gallons per person per mile (with a 500-person capacity). In other words, the plane achieves 100 miles per gallon (42 kilometers per liter) per person.
To put this into perspective, consider that a typical car gets about 25 miles per gallon. A road trip from New York City to Los Angeles, covering 2,797 miles, would consume 112 gallons of gas for the vehicle. With two passengers, this equates to 56 gallons per person. In comparison, a 6-hour flight covering the same distance would utilize 5,325 gallons of jet fuel, resulting in 27 gallons of fuel per person for a fully booked flight of 200 passengers.
The fuel efficiency of aircraft can be enhanced by improving aerodynamics, reducing weight, and optimizing engine brake-specific fuel consumption and propulsive efficiency. The Boeing 747's successor aircraft, with their improved engine efficiency and lower engine count, offer greater fuel efficiency. However, the 747 remains a viable option for cargo operations due to its large capacity.
The fuel consumption of aircraft has a significant impact on airline operating expenses, contributing to a large portion of the ticket price paid by passengers. With sustainability concerns gaining prominence, the high fuel usage of jet aircraft, such as the Boeing 747, has come under scrutiny. Nevertheless, the 747's fuel efficiency in terms of gallons per passenger-mile remains competitive, especially when compared to individual car travel.

A 5-hour flight would burn 18,000 gallons
A Boeing 747 burns an estimated 1 gallon of fuel per second, which amounts to 18,000 gallons in a 5-hour flight. This works out to be about 3,600 gallons of jet fuel burned per hour.
The amount of fuel burned per flight can vary depending on several factors. These include the aircraft's empty weight, payload, engine efficiency, flight path, and weather conditions. For example, a Boeing 747 flying from New York City to Los Angeles would burn approximately 5,325 gallons of jet fuel in 6 hours. This is because the distance between these two cities is 2,797 miles, which is less than the distance of a 5-hour flight assuming a constant speed of 550 mph.
The Boeing 747 is a large, quad-jet aircraft that can carry up to 568 passengers. Its maximum fuel capacity is approximately 63,000 gallons, which weighs about 400,000 lbs, or nearly as much as the empty plane itself.
The fuel efficiency of jet aircraft has improved significantly over the years. For example, the Boeing 787 Dreamliner is a twin-engine aircraft that burns approximately 2,700 gallons of fuel per hour. This is significantly less than the 3,600 gallons burned by the Boeing 747 per hour.

It's more fuel-efficient than a car
A Boeing 747 burns approximately 1 gallon of fuel per second, which equates to 36,000 gallons for a 10-hour flight. While this sounds like a lot, it can carry up to 568 people, which means it is burning 0.01 gallons per person per mile. In other words, the plane gets 100 miles per gallon per person. This is a much better fuel efficiency rating than a typical car, which gets about 25 miles per gallon.
When comparing flying to driving, we can consider a journey from New York City to Los Angeles, which is approximately 2,797 miles. Driving this route in a car with two passengers would require 112 gallons of gas, or 56 gallons per person. Flying the same route in a 747 with 200 people would use 5,325 gallons of jet fuel, or 27 gallons per person.
The fuel efficiency of a plane is also impacted by its speed, as planes fly at much higher speeds than cars. A Boeing 747 can fly at 550 mph, while the average car speed is much lower. Additionally, planes take a more direct path, while cars may take various turns along the route.
Another factor to consider is the number of people transported. A Boeing 747 can carry up to 568 people, while the average car occupancy in the US is only two people. This means that a 747 can transport more people with less fuel per person.
While the emissions from planes and cars are in the same range, the emissions from planes in the upper atmosphere may be more harmful due to their particulate emissions. However, modern twin-engine aircraft are significantly more efficient than quadjets, and the average fuel burn of new aircraft has decreased by 45% from 1968 to 2014. Airlines have also implemented strategies to reduce fuel consumption, such as flying slower and using more fuel-efficient aircraft.
