The airplane pilot must drop fuel immediately to avoid any problems during landing. This is important during an emergency landing. More information on this process can be found on the Fuel Dumping website.

Fuel dump or fuel dump is the traditional method used by aircraft pilots in an emergency before returning to the air base shortly after take-off. It is also used before landing for a short time to the destination or during an emergency landing to minimize the overall weight of the airplane.

This method is widely used by aircraft carriers in the United States and Great Britain.

Why is it necessary to dump fuel?

Airplanes typically have two different types of weight limits – maximum structural landing mass and maximum take-off mass, as specified by the fuel storage site. Full structural landing mass is always low and allows the routine airplane to take off at maximum weight, arrive with less weight and burn more fuel en route.

This is non-standard for non-standard aircraft as landing weight may be causing the problem. When an airplane takes off at its highest mass and lands before reaching its destination, it will contain more fuel than is needed for landing. This damages the structure and causes the plane to collapse before landing.

Given these problems, it is necessary to dump fuel, and all information related to dumping is readily available on the websites. Not all planes are eligible for fuel dumping, and you should become familiar with the planes that can drop fuel before landing.

Fuel Dropout Website: What Happens When an Airplane Dumps Fuel?

When an airplane pilot intends to drop fuel at an altitude, he presses a switch on the airplane to pump out the fuel nozzle by the wings. The engine fuel begins to dissipate over a large area and gradually evaporates to form fog. Fuel ejected from an airplane usually disappears to gas and then slowly to background gases.

However, when the plane is low to the ground, the fuel released by the plane remains in liquid form before it hits the ground. Dumping of fuel takes place overland or somewhere in empty places away from the population, as the process involves dumping thousands of liters of fuel ashore.

According to the Fuel Dumping website, fuel dumping is only permitted above 2,000 feet above the ground.

Which plane can dump fuel?

As mentioned, not all planes are able to dump fuel. On a smaller version of the aircraft, such as the Boeing 737, this is not required. Aircraft in the small version can burn fuel in the air, making many orbits in the air.

The larger version of the Boeing 747 is equipped with a fuel dump system so they can dump fuel to avoid problems when landing overweight.


The FAA is the official website where you can access all information related to fuel dumping. This fuel dump site investigates all incidents that have occurred as a result of overweight landing attempts.
