How much fuel does a 747 use in 1 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.
The Boeing 747-400F burns around 3,600 gallons of fuel per hour while cruising, which equals approximately 1 gallon per second or 60 gallons of fuel per minute. The Boeing 747-400F burns around a tonne of fuel during the 15-minute taxi between its gate and the runway.
For example, if we consider an airline flying medium haul flight of 2 hours with narrow body aircraft of about 200 seats, the efficiency is around 3.5l per 100PK for an 80% load factor, but it would go to 3.15l per 100PK with a 90% load factor.
Looking at light jets as a category, for example, they can consume anywhere between 134 and 222 gallons of jet fuel per hour based on the type of aircraft.
A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph). This means it can fly non stop for almost 16 hours!
Larger planes like the Boeing 747, on the other hand, have fuel jettison systems. If the aircraft tried to land without dumping the fuel first, it is considered an overweight landing attempt and could place immense stress on the airframe.
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).
Alternatives to driving or flying
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.
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.
Answer: The pilots have fuel gauges in the flight deck. There are also gauges for the fuelers. These gauges should read the same. Many airplanes have a manual system as a backup.
How expensive is jet fuel?
The price of jet fuel as of January 2022 is as follows: $2.46 (US dollars) per Gallon. 1 litre = 0.65 pence (pound sterling)
As of the beginning of 2022, on average, Jet A fuel costs $5.29 per gallon.
Even so, the typical range on a single tank of fuel for a private jet are typically about 1,500 miles for small aircraft. In most cases, this is enough to carry passengers to major destinations in the continental US without having to refuel.
A good estimate would be about 85% of the total fuel consumed would be done during cruise flight, with around 10% used during taxi, takeoff and climb and about 5% consumed during descent.
Second. That means that during a five-hour flight, a Boeing 747 will burn 18,000 gallons of fuel.
If it drops below the dew point, dew forms; if it drops below that and freezing, frost forms. In flight, the high speed air flow over the aircraft keeps its skin at essentially the same temperature as the air so it doesn't drop in temperature the same way.
Civilian and commercial aircraft generally don't have midair refueling abilities because of the expensive cost of outfitting commercial planes and training commercial pilots for mid-air refueling. Additionally, refueling commercial aircraft midair is largely unnecessary.
What is the longest flight in the world by distance? The longest flight in the world by distance is New York (JFK) to Singapore (SIN) on Singapore Airlines clocking in at 9,537 miles.
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).
Area and flight level
Specific areas have been designated where fuel dumping is allowed to avoid damage or harm where the fuel may drop; generally speaking, this is above seas or unpopulated areas above land.
Why do planes circle before landing?
Circling. Generally, planes will circle above airports for the same reasons planes sometimes need to perform go-arounds. This could be anything from weather to an incident on the runway. Pilots have to weigh their options between circling for a little while or turning back to land at a different airport.
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.
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.
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].
For the shortest trip, driving is more economical than flying. But for the longer cross-country trip, flying is far cheaper. And keep in mind that this only considers solo drivers. Families or friends traveling in one vehicle can save money by driving, even on longer routes.
One of the biggest fuel savings has come from flying aircraft more slowly. From the perspective of fuel consumption, there is an optimal cruising speed for each aircraft based on altitude. Flying faster increases the amount of fuel burnt.
Power to overcome it is proportional to drag times speed - so is proportional to speed cubed. To go twice as fast you have to push 4 times as hard at twice the speed, requiring 8 times the power. And 8 times the fuel burn.

| Boeing 747 | $37,917.72 | $235,340.64 |
According to The Occupational Outlook Handbook, the US Bureau of Labor Statistics posits that for an airline pilot the annual salary ranges between $80,920 and $208,000.
Small piston-engine powered aircraft often have a single tank fuel system. On newer aircraft, two fuel tanks, with one in each wing, are more common. A two tank system requires additional components to allow controlled provision of fuel to the single engine.
Do pilots have to pay for fuel?
Most airlines will work the total fuel required, which is presented to the pilots, through their flight planning system. The pilots will then make a decision as to whether they require any 'extra' fuel.
There is also what is called "contract fuel". Basically there is a company that is a middleman, a fuel supplier who pays the airport fuel company and then rebills the airline. The pilot has a card that identifies them as a client of the fuel contractor. For example, check out AEG Fuels, a typical fuel contractor.
Not always. Small aircraft pilots usually do, but airliner crews set takeoff throttles to achieve safe operation while saving fuel and engine(s) wear.
A small plane can have a fuel capacity of 4000–5000 liters, a mid-sized plane can have 26000–30000 liters, a wide-body jet can have 130000–190000 liters, and a very large jumbo jet can have 200000 liters to 323000 liters.
Jet A fuel consistently costs less than 100LL due to its simpler refining process, ease of transportation (via pipelines because it does not contain lead), and economies of scale from the volume of demand.
The word's shortest nonstop flight is a tiny hop between the islands of Westray and Papa Westray in the United Kingdom, a mere 1.7 miles (2.7 km) apart.
Just as the crude supply shrinks, demand for fuels refined from it is growing. The worldwide return to airline travel has driven up demand for jet-A, but the booming freight and shipping markets are clamoring for diesel fuel. Limited supply means both industries are paying more for fuel.
Airlines receive nearly 60% of their revenue from passengers directly (the other 40% comes from selling frequent flyer miles to credit card companies and other travel partners like hotels and car rental agencies). That revenue includes the cost of airfare, fees, and other travel expenses the airlines charge.
The reason behind ATF price being lower than that of petrol and diesel is the way tax on these fuels are calculated. Just like the conventional vehicle fuels, ATF too attracts both central and state taxes, and it varies from state to state due to different VAT rates.
Planes continue to glide for long distances even after running out of fuel. At some point, though, the fuel would have run out. An aviation expert said most new-generation aeroplanes would continue to glide, even after all the plane's fuel reserves had been exhausted.
Do planes ever stop flying?
Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.

A Boeing 747 can hold approximately 48,400 – 57,285 gallons of jet fuel depending on the model of aircraft (model series 100 – 400). This is 183,214 to 216,847 liters of fuel or about 180 to 213 tonnes.
Fuel jettisoning systems can dump thousands of pounds a second. Most can get a plane back down to its max landing weight in 15 minutes or less, and it's usually as easy as flipping a switch in the co*ckpit.
It takes about 45 minutes to one hour to fuel the aircraft, and the process begins no later than 90 minutes before the flight. (At 80 minutes, an airline's operations team will call the fuel team to check in; chop chop!) The fuel is pumped at a very fast clip.
For comparison, the F-15 is $40,000, the F-16 is $23,000, and the A-10 is $20,000 per flying hour.

A Boeing 747 burns approximately 10 to 11 tonnes of fuel per hour. Per second, this equates to approximately 1 gallon (about 4 liters) of fuel. This is approximately 5 gallons of fuel per mile (12 liters per kilometer).
The average hourly rental rate of the Boeing 747-400 is around 30,950 USD per hour.
A jet aircraft uses a phenomenal amount of fuel. While several more fuel-efficient aircraft are traversing the skies today, a Boeing 747 quadjet burns up to one gallon of fuel every second.
How much does a 747 burn fuel?
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). According to Boeing's Web site, the 747 burns approximately 5 gallons of fuel per mile (12 liters per kilometer).
A 747 can seat 380 to 560 people, depending on how an airline sets it up. A full one is a moneymaker. But an airline that can't fill all the seats has to spread the cost of 63,000 gallons of jet fuel — roughly $200,000 — among fewer passengers.
The good news is that pilots are supposed to dump fuel at a safe height above the ground and away from other aircraft, and in addition, over as remote an area as possible. In the case of Heathrow, for example, most fuel dumps have occurred over the sea.
In fact, it is normally done only in emergencies or when a pilot needs to land a plane quickly for some reason. It is not a standard procedure. One example of an emergency is a passenger who is experiencing a medical emergency, therefore, making it more serious to land the plane quickly.
As of the beginning of 2022, on average, Jet A fuel costs $5.29 per gallon.
Fuel is one of the highest costs for airlines, accounting for 20-40% of expenditure depending on price and region.
Air traffic represents less than 2-3% of the global CO2 emissions whereas road traffic accounts for around 10% of these direct emissions. Still, planes remain among the most polluting means of transport, together with cars.
On a daily basis, the average cruise ship uses around 140-150 tonnes of fuel, or 30 to 50 gallons per mile. Like vehicle travel, hitting higher speeds increases drag which results in more fuel usage. Generally speaking, the majority of cruise ships find that 21-24 knots to be the most efficient speed.
Hawker 800XP is a midsize jet that burns the most fuel per hour. On average, a Hawker 800XP can burn about 291 gallons of fuel per hour. On the other hand, the Learjet 60 is another midsize jet that consumes around 215.10 gallons of fuel per hour.
