What gives Airlines the right to dump their fuel
71
How long has this been happening ?
When jets first started flying with US airlines in the late 1950s, the FAA rule in place at that time stated, if the ratio between an aircraft's maximum takeoff weight and its maximum landing weight was higher that 105%, it had to have a dumping system installed.
Boeing introduced the 737 in the 1960s along with the DC-9 which was made by Douglas Aircraft company. Both of them were used for short runs so the dump system wasn't even in the equation.
Fuel dumping doesn't happen very often, in 2007 there was none recorded and in 2008 one dump happened. Bigger planes like the Boeing 747 has to dump if in emergency situations because if they don't they would be way to heavy to land.
Determining Where to Dump
Any time they have to dump they prefer to do it over water when possible, if they can't do this, they try to find areas that are unpopulated to distribute its fuel. It takes a short amount of time for the fuel to evaporate so they dump from 6000 feet or higher to get the proper amount of time to do the job.
It's hard to nail down the exact area that is being affected by the dumping, there are so many determining factors that are involved with those figures. They also say it depends on the quality of the fuel, the temperature, speeds, winds, humidity and more, but there is nothing concrete about what it's doing to us or the environment at this time.
Whirlwinds or fuel dump that is a good question.
A phenomenon in the form of a whirlwind may happen during a landing, which is sometimes interpreted as being a fuel dump. Leaving behind whirlwinds is normal for air crafts, and when the weather outside is humid, they become visible due to condensation of the vapor from the water that is in the air.
This is a rare event they say...
Despite the growth in volume, the number of causes in which aircraft had to blow there fuel has not increased in the past few years. Since 1990 around five cases of fuel dumps had been recorded. It is so few and far between they say there is nothing to worry about
Well as much as I have studied this subject, there is nothing being hurt by the amounts of fuel dumps that has gone on for the past 20 years. Any time you would like to see how much has been dumped please go to http://www.skyguide.ch/en/Dossiers/Dossier_Laerm_und_Umwelt/FuelDumping/

Hi stars, thank you for your wonderful comment. have a great night my good friend.
:)
wolfpack5, this has been a well known fact for years. Aviation fuel dumping has been practiced with commercial airlines for safety sake for a long long time.
If that is a concern for you, check this out.
You know these commercial airlines we see flying over head, and especially in the mornings, you can see a huge stream of exhaust in the sky, as they fly by, well thank goodness and thank God, that no terrorist has thought of this yet, but if they desired to do so, chemical or germ warfare agents could be burned off at the same time and released into the atmosphere, and if the plane is like 5 miles up or say 30,000 ft. in the air as the did this no one would be the wiser, until it was to late, and these exhaust streams cover quite a bit of distance and area as they disperse. Think about it?

Hi Dave, I dont really have a concern. I enjoyed writing this hub, learning things like this is cool. It was fun :)
Have a great night my friend...
Dave,
Chemical or biological agents released that high up would never touch the ground. It's the reason why this has not been tried by terrorists. Chemical and biological weapons must be release/detonated near ground level to have an impact on it's target.
I've been through too many military training exercises on this very thing to not make a correction to your post.
OneWhiteSquare, thank you for your comment. after reading up on this subject, I found that it just evaporates before it hits the ground. Im not worried :)
Have a great night...
Great hub. I learn something new everytime I come.
Hi granny's house, thank you for stopping by. I'm very happy you liked it :)
have a great night....
Wow, I had no idea and I fly all the time! This is good to know, thanks for sharing!
Good Morning my Lady, Very happy to see you here I didnt realize this was happening until I seen it on a web. Learn something new everyday.
have a wonderful weekend my friend :)
Usually i fly most of times because i love to travel. But i did not hear about this before. Thanks for sharing such a nice hub and information. Really its polluting the environment and we should not do this.
Thanks again for this hub.

Thank you for another wonderful hub. The knowledge you provide us as well as society is very useful. We need to protect our planet so that the world can be a safe place for humans and animals to live well. Your concern for oceans, seas, sea creatures, beautiful land animals, and your concern for a safe ecological earth system is a dire important matter. Every supportive word you say does save the lives of humans and wildlife because good people and wise people listen and learn. God Bless You and your family and wishing you a wonderful restful night in God's arms.
