What is the requirement of fuel dumping?

Welcome to today’s blog.....

Let’s talk about what is fuel dumping on the aircraft and in what situations it is allowed? Fuel dumping is a process of ejecting an extra amount of fuel in travel. This phenomenon is required in several conditions such as emergency landing, engine failure, technical malfunctioning, and overweight landing. The total flight weight is calculated before, the flights take-off which are as follows: Dry operation weight (Laden weight) + payload (cargo+passengers) = zero fuel weight + calculated fuel for destination = Take-off weight.

For every aircraft, there is a maximum landing weight allowance provided by the manufacture which is a threshold value of the weight. If the flight carried weight > threshold value, i.e., overweight landing and vice versa. So the pilots have to maintain the flight weight lower than the threshold provided, to have a safe landing. Due to extra weight (overload), the pilots decide to dump the fuel in the air so they reach the required weight for landing. For instance, you are traveling from the USA to Europe- Germany during the flight the pilots realized that there is technical malfunction so they have to make an emergency landing in Dublin or to any nearest airport. However, the fuel they carried from the USA was up till Germany, therefore, they have to inform ATC about the situation, and then they can dump the fuel recommended at higher altitudes so it doesn’t reach on the ground. 

I hope you find it interesting. See you on Monday.
