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.
How much fuel does a Boeing 737 burn on take off?
A Boeing 737 typically burns around 2,500 to 3,000 pounds of fuel during takeoff, depending on factors such as the specific model, weight, and environmental conditions. This equates to approximately 1,200 to 1,400 liters of fuel. The fuel consumption can vary based on engine type and operational procedures. Overall, takeoff is one of the most fuel-intensive phases of 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
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 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.
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...).
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.
How much fuel takes when 737 taking off?
The fuel consumption of a Boeing 737 during takeoff varies depending on the specific model and load conditions, but it typically burns around 3,000 to 5,000 pounds (approximately 1,360 to 2,270 kilograms) of fuel during the takeoff phase. This amount can be influenced by factors such as aircraft weight, weather conditions, and engine type. Overall, takeoff fuel consumption represents a small fraction of the total fuel used for a flight.
Why is landing gear retracted immediately after take off?
Landing gear is retracted immediately after takeoff to reduce aerodynamic drag, allowing the aircraft to gain altitude and speed more efficiently. Retracting the gear also helps streamline the aircraft, improving fuel efficiency and performance during the climb phase. Additionally, it enhances safety by minimizing the risk of damage or malfunction related to the landing gear system during the critical phase of flight.
How much fuel does a 737 use for takeoff?
A Boeing 737 typically uses between 1,800 to 2,500 pounds of fuel during takeoff, depending on the specific model, weight, and environmental conditions. This translates to approximately 270 to 370 gallons of jet fuel. Factors such as payload, weather, and runway length can affect fuel consumption during this phase.
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.
