Have you ever looked up and saw an aircraft flying with long white lines like gas behind it ? I’ve seen it many times and what the aeroplane is doing is called fuel dumping. Now you’ll be wondering why pilots will dump fuel considering the fact that aviation fuel is very expensive and also causes serious pollution to the environment. In this post techcapon be explaining to you why it is necessary for the pilots to dump fuel sometimes.



Now this also includes our local airlines in Nigeria like DANA, AERO etc. Although fuel dumping is more common with airlines that travel long distances and make international flights. Before take-off, the airline do the maths. They calculate how much fuel is needed to the aircraft to complete their journey and they fill the aircraft tanks with enough fuel to make the complete their journey. There are some terms I’ll like to explain in this post for you to understand how it works.

Dry operating weight: This is the weight of the plane without fuel, passengers or luggage.

Payload: This is the weight of the passengers and their luggage

Zero fuel weight: This is the weight of the fuel needed to reach their final destination including reserve.

Dry operating weight + Payload + Zero fuel load = Take-off weight

Take-off weight MUST always be greater than landing weight



The major reason why pilots dump fuel is because the landing weight of the plane exceeds the maximum. Inside the cockpit, pilots have a meter that tells them the weight of the aircraft at all times. For example, Boeing 747 aircrafts have a maximum landing weight of 312000kg.

Anything above that weight will cause the aircraft to suffer serious damage during landing or even crash during landing. Infact, if the maximum take-off weight is above 312000kg, the cockpit will blink red lights and give the pilots warning. The question on your mind right now will be, if the airline calculates how much fuel is needed to arrive their destination, why dump fuel before arriving ? The answer is simple.

EMERGENCY

For example, a plane that’s suppose to fly from Lagos to New York city loads enough fuel to reach their destination. Everything is going fine then suddenly a pregnant woman who is on board goes into labor. If there’s no nurse on board and the flight attendants cannot handle the issue, the only choice will be to make an emergency landing.

The flight crew will alert the pilots on the situation and the pilots will have to land in the nearest airport. The first thing the pilots will check is the weight of the aircraft. For an aircraft that has enough fuel to reach New York, of course the landing weight will be far above normal. In this scenario, the pilot must dump enough fuel in order to reduce the weight of the aircraft before landing.



The pilots have no choice. There are 3 things that add weight to an aircraft. Passengers, luggage and fuel. Obviously the pilots cannot dump passengers. Neither can they dump cargo (except in very rare cases), the only option is to dump fuel.

The pilot will dump the fuel, make the emergency landing in order to get the pregnant woman to the hospital, refuel before they can continue the journey. Of course dumping fuel is a big loss to the airline companies. They lose big money anytime these things occur but it’s better to dump fuel than land an overweight aircraft thereby damaging the aircraft or jeopardizing the lives of everyone on board.

Really?


I am also thinking that for the long flights or international flights, the plane is filled with excess fuel in the event that their is an emergency on getting to the destination. In that case the flight may be diverted to another airport and that will require additional fuel. So but if everything go well, and the plane is to land normally in the proposed destination, the excess fuel added in case of emergency will definitely have to be dumped. ...right?

Nice lecture, now i know what fuel dumping means! Thanks!

Ok nah...

hw

it would be disastrous crashing with the fuel..

Nice lecture, now i know what fuel dumping means! Thanks!

ur welcome

Ignorance is really a disease.
When I was younger, anytime I see that whitish clouds from an airplane, I always thought it was a jet moving very fast.
Thanks bro for enlightenment

Interesting

Thank you for this. . .

shows technology is still a baby, dumping fuel is still d solution.

kinda feel like engineers n fuel sellers working hand to hand here.

U deserve a bottle of cold beer op. Tank u very much

I know our ladies will not read this

Very educative..

Educative... Well done.

will the pregnant woman be charged for the dumped fuel

More of this please. Thanks @ OP

This is the sort of thread that should be on front page, informative and educative

Great lecture. I have learnt new thing today.

White clouds behind airplanes aren't fuel, don't let the OP mislead you.

Those white streaks planes leave behind are actually artificial clouds. They're called contrails, which is a shortened version of the phrase “condensation trail." Airplane engines produce exhaust, just like car engines do. As hot exhaust gases escape from a plane, the water vapor in the fumes hits the air.

TechCapon, stick to your tech blogging about chargers and earpieces and stop misleading people. You think pilots dump fuel indiscriminately? Nigger thinks aviation fuel is tap water.

The reasons arent satisfactory. Upon all the content of flight na only fuel you wan dump to reduce weight ?? I 'll research on that...

Good one

somto10:
I never enter plane b4 na
hw i go take kno?

You don't have to enter a plane to see and understand what the writers just explained in the sky

Techcapon!!!!!!!!!!!!

We go fight oh. Abeg nor de run away abeg, posts like this are the reasons I come to frontpage

Not Timaya is fighting Tuface or DBanj is on his way to Haiti and all those other bull crap!

Interesting

overdrive:
will the pregnant woman be charged for the dumped fuel

no! never! its the baby that'll be charged...

OP IS TOTALLY WRONG.... PLEASE DON'T MISLEAD PEOPLE. DO YOUR RESEARCH BEFORE POSTING

Educative and informative

What you saw was from the airplanes engine gases hitting the air. Not one dumping of fuel.
