Airplane fuel efficiency

A plane like a Boeing 747 uses approximately 1 gallon of fuel (about 4 liters) every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters).

What's the most fuel-efficient airplane?

Otto Aviation says its aircraft is the "most fuel efficient" commercial aircraft in existence. The company announced it will soon be powered by hydrogen and offer "cheaper" travel for distances up to 1,000 miles.

How much fuel does a plane use in 2 hours?

The flight will consume an average of 5,016 litres of fuel in the entire journey of 1200 kilometres. Comparatively, a bigger flight like the Boeing 747 will approximately use 4 litres of fuel every second. This gives an estimate of 14,400 litres per hour and 240 litres per minute.

How much mpg does a plane get?

Aircraft efficiency differs, as do the conditions on different routes—a domestic airliner can get anywhere from 45.5 to 77.6 miles per gallon per passenger, with an industry average of about 51 miles per gallon of fuel per passenger.

Does flying slower save fuel?

Mostly fuel efficiency — less air pressure is less resistance to going forward, so less power and less fuel is needed to go the same speed.

Is flying more fuel-efficient than driving?

According to an ICCT report, on comparable trips in the United States, a plane gets 43 miles per gallon per person; this is less efficient than trains or cars, which get 51 mpg and 53 mpg per person, respectively.

How much fuel does a 747 burn per hour?

Boeing 747 fuel consumption If an Airbus A321neo burns 0.683 litre per second, Boeing 747 uses approximately 4 litres every second, which translates to 240 litres per minute and 14,400 litre per hour.

How much does 1 gallon of jet fuel cost?

As of the beginning of 2022, on average, Jet A fuel costs $5.29 per gallon.

How much fuel does a plane use per hour?

Most commercial planes burn several thousands of gallons of fuel per hour while flying. For example, the Airbus A380 burns over 4,000 gallons of jet fuell per hour when cruising. Most commercial planes hold several tens of thousands of fuel for that reason, with the Airbus A380 holding up to 82,000 gallons.

How much does it cost to fuel a 747?

The cost to fuel a plane largely depends on local fuel prices and the supply of crude oil. Going by averages, it would cost between $170,000-$200,000 to fuel a Boeing 747-8. The Airbus A380-800 costs more at $230,000-$260,000 to fuel.

Do planes use more fuel than cars?

This means 124,3 liters of jet fuel per passenger. In this case the fuel consumption per passenger on the airplane is even better than driving with 2 persons in a car. Or we need 152 Volkswagens to transport 344 passengers to New York and then we burn the same amount of fuel as the plane.

How much fuel does a 747 burn per flight?

While several more fuel-efficient aircraft are traversing the skies today, a Boeing 747 quadjet burns up to one gallon of fuel every second. Every. Second. That means that during a five-hour flight, a Boeing 747 will burn 18,000 gallons of fuel.

Can a plane run without fuel?

Fuel is a must for an aircraft. Without fuel, the engines won't work. If the plane runs out of fuel while in the air, the plane must be refuelled. Otherwise, the plane will crash.

Why do pilots drop fuel?

Why dump fuel? The reason to dump fuel is simple: to drop weight. Any given aircraft has a Maximum Landing Weight (MLW) at which it can land, and in most cases that weight is lower than its Maximum Takeoff Weight (MTOW).

What speed saves the most fuel?

7. The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it's illegal too).

Does flying high save fuel?

Finally, longer flights benefit from flying at higher altitudes; the thinner air reduces drag, increases engine efficiency, and saves fuel.

Does flying faster burn more fuel?

The same is true on an aircraft. The faster you go, the more fuel you burn. Drag, which causes the increase of fuel burn, is actually proportional to the square of the speed [addendum: energy to overcome drag is proportional to the cube of the speed].

How much fuel does a plane use per mile?

Surprisingly, on a per-passenger-basis, airplanes are actually quite fuel-efficient. According to Boeing, a 747 usually burns around 1 gallon of fuel (around 4 liters) every second. A Boeing 747 will then burn about 5 gallons of fuel per mile or 12 liters per kilometer.

How far can a 747 go on a tank of fuel?

It can carry a maximum of 238,604 liters of fuel and it has a range of about 7,790 nautical miles. A Jumbo Jet (Boeing 747-400) flying from London to New York burns approximately 70,000 kilograms of fuel.

How much does 1 gallon of jet fuel weigh?

Jet-A fuel density limits are established by the American Society for Testing and Materials (ASTM) Specification D1655. At 60°F the density limits are from 6.46 to 6.99 lbs/gallon. In a G450, this equates to a range of: 28,230 lbs at 6.46 lbs/gallon.
