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.

OP's post isn't wrong (cos fuel dump also creates white trails), but it's very misleading. That is because 90% of the times you see those white trails, it's actually contrails and not fuel dumping; fuel dumping happens only very rarely.

As an engineer , there are some parts that does not add up in the write up , if he said the maximum take off weight is 312000kg and the maximum landing weight is also 312000kg , and that any over weight will indicate , it then mean that the air craft can't take off with weight exceeding the maximum so why dump expensive fuel if u take off with maximum and will land with same maximum , abi plane de add weight for air or some passengers go enter for cloud?

TechCapon:
I know what contrail is. Stop making fool of yourself. Are you saying that fuel dumping never occurs or what?

You should be ashamed of your crazy mind.

Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of its intended destination (emergency landing) to reduce the aircraft's weight.

I quickly confirmed online before I commented. Even the bible says after hearing "they continued examining the scirptures daily as to whether the things are true".

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.

We learn everyday. I ask a friend of mine just last week the reason for the white smoke he said the white smoke stand for peace. He said when an aircraft is flying above a troubled state or country(country like Nigeria with boko haram wahala), they release the white smoke. Thank for this info.

Yeah... it's always good to confirm, but hope you also tried to confirm what I said too about contrails being the more prevalent reason behind those white trails and not fuel dumping which happens very rarely (mainly during emergencies)?

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