​Why Planes Dump Fuel Before Emergency Landings?

NewsPoint

​​Passenger & Crew Safety​

The primary objective of fuel dumping is to prioritise the safety of passengers and crew members. By reducing the risks associated with a heavy landing and potential structural damage, fuel dumping helps safeguard the lives of those on board.

​​Safety Of Landing​

Dumping fuel helps reduce the weight of the aircraft, ensuring a safer landing. The plane needs to be lighter to avoid exceeding the maximum landing weight limits.

​​Prevent Structural Damage​

Landing with a fully loaded fuel tank can put excessive stress on the aircraft's structure. By dumping fuel, the risk of causing damage to the landing gear or other critical components is minimised.

​​Control Center Of Gravity​

Fuel dumping helps maintain the aircraft's centre of gravity within safe limits. It ensures the plane remains stable during landing, reducing the risk of instability or loss of control.

​​Airframe Stress Reduction​

The act of dumping fuel reduces the stress on the aeroplane's airframe, including the wings, fuselage, and other structural elements. This helps prevent potential damage during an emergency landing.

​​Fire Hazard Mitigation​

In some emergency situations, there might be a fire or the potential for fire on board. Dumping fuel at a high altitude helps disperse the fuel, minimising the risk of an inflight fire or explosion during landing.

​​Environmental Considerations

When fuel is dumped, it evaporates before reaching the ground. Although it is an unfortunate necessity, efforts are made to dump fuel at higher altitudes to minimise the impact on the environment.

​​Avoiding Excessive Fuel Load​

Landing with a full fuel load can be dangerous, as it increases the risk of fuel leaks or spills. Dumping fuel reduces the amount of flammable liquid on board, reducing the potential hazards during an emergency situation.

​​Regulating Landing Weight

Aircraft have specific weight limitations for landing. By dumping fuel, the plane ensures it remains within the prescribed weight limits, avoiding any strain on the landing gear or other structural components.

​​Enhanced Manoeuvrability​

Dumping fuel helps improve the manoeuvrability of the aircraft, making it easier for the pilot to control and stabilise the plane during the emergency landing.
