The question is why ‘fuel dumping’ is done before emergency landing? The answer is that the weight of oil in the aircraft is very high, due to which there can be problems on emergency landing. Therefore, the weight of the aircraft is lightened by dropping oil.
Do you know that there are some situations when a pilot of a plane has to drop all the oil of the aircraft in the air. Pilots do this work by flying in the air. It is not that they wait to land on the ground. Although such work is rare, but in emergency the pilot has to do it. You must be thinking how difficult it would be to stand on the earth after that much oil of the aircraft was spilled. So the answer is that during the spill of the oil from the plane, it does not reach the earth, but rather the smoke blows in the air.
It can be understood by an incident. On 23 March 2018, a plane from Shanghai was flown to New York. A 60-year-old woman aboard in it suddenly worsened and began to have trouble breathing. The situation became unconscious. Therefore, the pilot was finding no other way than emergency landing. But it was hard work.
The crew member decided that 65,000 pounds of gasoline of the aircraft would have to be dropped into the air. This was done, then the emergency landing of the plane in Alaska could be done. After dumping oil of about 20 thousand dollars, the emergency landing of the aircraft took place and the life of the female passenger could be saved.
What happens to fuel dumping
The question is why ‘fuel dumping’ is done before emergency landing? The answer is that the weight of oil in the aircraft is very high, due to which there can be problems on emergency landing. Therefore, the weight of the aircraft is lightened by dropping oil. Then its emergency landing takes place. This method is called ‘fuel jettison’ in technical language. The plane is designed in such a way that it can land only with a certain weight. If the weight of the aircraft is high, then it is possible that it will push fast on the earth and cause big damage.
How much oil in the plane
The plane contains 5 thousand gallons of oil at a time, which is equal to the weight of three elephants. In such a situation, landing with full tank is very risky. Therefore, never land the plane with a full tank or high amount of oil. Before the plane takes off, the flight planners estimate how much oil will be used in a trip. During the trip, almost the oil runs out and the plane lands comfortably. Sometimes it happens that there is oil left in the plane before landing, then the pilot burns the oil by making rounds of the aircraft before landing and then landing it. In such a situation the pilot decides to dump oil in the air and land the aircraft.
When is emergency landing
During the flight, if someone has a medical emergency, there is a situation of death and in this situation it is not right to keep the aircraft on the flight, then the pilot decides to dump the fuel. Dumping does not mean that the oil is spilled but that the oil is burnt rapidly by circling the aircraft. But if a passenger dies, the oil of the aircraft can also be spilled in the air. It is decided by the pilot and crew members.
