Burn fuel is generally used more during takeoff and landing compared to cruising. During takeoff, aircraft engines operate at full thrust to lift off, consuming significant fuel. Landing involves a different fuel consumption profile, as engines are usually throttled back, but the overall fuel usage during takeoff and landing phases is still higher due to the increased power needed for takeoff and the additional energy required for approach and descent.

What is the difference between takeoff weight and landing weight of aircrafts and how it calculated?
Takeoff weight is the total weight of an aircraft at the moment it lifts off the ground, which includes fuel, payload, and the aircraft itself. Landing weight is the weight of the aircraft at the moment it touches down on the runway, which is typically lower than the takeoff weight due to fuel burn during the flight. These weights are calculated based on the initial weight of the aircraft, fuel consumption, and payload changes during the flight.
Why airplanes burning off fuel before landing?
they do that if it crashes or doesn't make a proper landing and if it catches fire there is no fuel to burn and there is a lot less chances of it blowing up
Why is a rich mixture used during take off?
A rich mixture during takeoff provides more fuel to the engine, ensuring ample power output for a quick and efficient climb. The extra fuel also helps cool the engine during the high workload of takeoff.
What is fuel capacity does a hawker harrier have?
The Hawker Harrier has a fuel capacity of approximately 3,000 liters (around 792 gallons) when using its internal fuel tanks. This capacity can be increased with the addition of external fuel tanks, which can enhance its range and endurance during missions. The aircraft's design allows for efficient fuel management to optimize its vertical takeoff and landing capabilities.
Why is jet fuel measured in pounds?
Jet fuel is measured in pounds because it is a unit of weight that is used to quantify the amount of fuel loaded onto an aircraft for safe operation. By measuring jet fuel in pounds, it allows for accurate calculation of the weight and balance of the aircraft during flight planning and ensures that the aircraft stays within its weight limitations for takeoff and landing.
Do aircraft dump fuel before landing?
Not normally. This is an emergency procedure sometimes done because the maximum takeoff weight is usually larger than the maximum landing weight on aircraft carrying large passenger or freight loads. The dumping of fuel is one action that can be used in an inflight emergency; however, I can guarantee that the takeoff weight of ANY aircraft (unless refueled in flight) is ALWAYS greater than said aircraft's landing weight. Fuel used enroute will always reduce the gross landing weight. Aircraft are generally serviced with enough fuel to make its primary destination and an alternate runway (due of emergency). The landing weight can be adjusted by dumping fuel (normally) in case of damage to the aircraft or destination runway conditions (snow/ice, rain) requiring a lighter aircraft gross landing weight. Naval aircraft operating from Carriers routinely dump fuel to adjust for landing conditions (wet deck, reduced landing area, slower ship speed into the wind, etc...).
How is the fuel consumption of Boeing 767-300er?
The exact fuel consumption is variable as certain periods such as takeoff and early cruise will burn more fuel. That being said, at cruising altitude a 767-300ER with the RB211-524H power plants will burn around 4200 kilograms per hour.
Do space shuttles use fuel?
Space shuttles use fuel when taking off and for control while in orbit, deorbiting, and landing. The main takeoff engines use liquid hydrogen and liquid oxygen, and there are two solid-fuel rocket boosters. In orbit, the shuttle uses thrusters that burn hydrazine and nitrogen tetroxide.
How much fuel does an f 16 burn?
An F-16 fighter jet typically burns around 3,000 to 5,000 pounds of fuel per hour during combat operations, depending on factors such as speed, altitude, and mission profile. In a more efficient cruising mode, fuel consumption can drop to approximately 1,200 pounds per hour. However, during takeoff and high-speed maneuvers, fuel consumption can spike significantly. Overall, the exact fuel burn can vary widely based on the specific mission and operational conditions.
Why do aeroplane takes wheels inside when flying?
The landing gear is retracted after take-off. This is because, when the plane is flying at great speed the landing gear produces a lot of drag. This slows the plane down. So the landing gears are retracted.
What is the fuel used in space shuttles while landing?
The space shuttle only use the liquid fuel that is onboard to start the decent process. They burn their engines to slow down just enough for the earths gravity to begin pulling them back to earth. After that, they are simply big gliders.
Do commercial jets dump its fuel before landing?
In general: no, not on a normal flight. Any fuel "left over" in the tanks will be used for the next flight. Airliners only dump fuel when they are too heavy to make a safe landing - and this situation only occurs when the landing happens much earlier than planned, such as a diversion or an emergency landing. Not all commercial airliners can dump fuel, some have no option but flying around for a while to "burn off" fuel before being light enough to make the above-mentioned early landing.
