- A pilot will choose to dump fuel only on very rare occasions. In the case of an emergency situation they can choose to dump, dirty up the plane or land heavy. Each has its pros and cons but here's why it's done in the first place.

Why Planes Dump Jet Fuel - วิทยาศาสตร์และเทคโนโลยี
Because you can't dump passengers, lol.
😂😂😂😂
lmfao
😭
This is why Trump is your President

Imagine planes dumping fuel that shape like stairs
Why imagine? We’ve just seen it!
Such cheap, crap video animations used by this channel.
Duh those stairs are how you get in the plane.
Lmao
United airlines dump passengers to reduce weight of the plane.
I thought it was the spirit airlines
That is so old but true.
Boeing...
Because the average American is overweight.
Heyyy
“But the Environmental Protection Agency just isn’t worried about it”
That applies to a lot of things.
Which EPA? The UN? Fuel is dumped worldwide.
Ephesians 6:10-18 Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; and your feet shod with the preparation of the gospel of peace; above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God: praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints. The bible is no old book. You have to really let Christ open your eyes; to see the world in shambles. Many people say it's a religion to lock up people in chains, and say it's a rule book.. why? Because people hate hearing the truth, it hurts their flesh, it's hurts their pride, it's exposes on what things have they done..people love this world so much, s*x, money, power, women, supercars.. things of this world. Still trying to find something that can fill that emptiness in your heart. You can't find that in this world.. only in Christ, the bible is no chains, it's a chainbreaker. Breaking your sins into pieces... Repent now, and turn back to the true Lord only.. God bless.
😊
But they are worried about diesels but like they said.
The .01% that planes do dump fuel is still 20 million gallons dumped in the atmosphere if that number still holds true in 2018 and even 2024. But the EPA is worried about diesels and not the 20 million gallons of jet fuel. Huh, I guess if you pay the EPA enough money, they don't care.
I’d like to add something... dumping fuel is rare because most of the time the quantity of fuel loaded in a plane is the fuel needed to do the trip he’s going to do according to the extra fuel, contingency fuel etc it has to have. Also the Boeing 737 can not dump fuel. What they actually do is flying at lower altitude or flying with flaps, landing gear to increase drag and therefore increase fuel consumption.
Or just do an overweight landing.
737 fuel overflow vent is what I witnessed apparently. The vents (NACA ducts), located near each wing tip, provide a small positive head of pressure on the fuel in all three tanks. This prevents a vacuum forming as fuel is used, assists the fuel pumps and reduces evaporation. NB if you overfill the fuel tanks, then this is where the ensuing fuel spillage will come from!
Mister Apple She just explained the reason why people would need to dump fuel... and what you said doesn’t negate that.
Well that's what the video says...lol
@Shubham Mishra Because he pretty much just rewrote the video's explanation. Why do you need to spam useless crap all the time?
Thousands of gallons a second... 15 minutes... hmmmmm
Looks like your the only one who realised the math isn't adding up.
The Real answer? This video is propaganda to reinforce your belief that commercial jets use fuel. In reality once started and warmed up no fuel is required for a jet engine to run. What?! The jet turbine engine can and does run.. combusting superheated compressed air.
"Jet fuel" is only used for cold starts.
So, this video is nothing more than.. hot air. Lol.

Answer: the plane loses weight so its easier to land on the water or land
Answer: the plane loses weight so it's below it Maximum Landing Weight.

@@ay_kay_en he try to say he is getting fire as a pilot and now work as s1 that fuel the airplane instead bechz he spilled too many fuel as a pilot. Thats why he use 'use' instead of used. But well, i never see "use to" use like this

Why do Birds Poop in Mid Air
@Ziad Khaled ha ha
@@GabrielKnightz maybe not
@@GabrielKnightz
I would if i could.
😂😂😂😂
If they land without pooping, they will stress their bodies from the added weight and this could damage their legs or manifest itself as a problem on a future flight. They are not designed to land with a full poop load. It is expensive to poop mid flight and studies are inconclusive about the risks to health. The poop is meant to vaporise but sometimes it reaches the ground and lands on ur face. They should only poop mid flight when absolutely necessary.
I don’t think that woman’s life was worth all the damage that dumping raw fuel into the environment did.
Eric x its the crew’s responsibility to save people when in an emergency, your basically saying pilots should crash the aircraft instead of landing delaying other people.
to lose weight. done
Like in American dad when Roger is ridding a horse and start vomiting to go faster. Probably an obscur reference sorry
@@bazooka-sharks-parker lmao very obscure
Quick answer: fuel is heavy, and the heavier the plane, the faster it needs to land. The faster the landing, the more runway is needed. In an emergency case with no fuel dump mechanism, a pilot may choose to land overweight
Sometimes i feel like, the more i know, the less i want to know...
I think everyone knows why, but we just wanted to know why 5 minutes was needed to explain it
United Airlines: Greetings, dear passengers. The aircraft needs to execute emergency landing; therefore, we need to loose weight to ensure our landing is safe. Please, remain calm and be collaborative. Passengers from the economy cabin may unbuckle the seatbelts as a flight attendant will carefully select random people that will be dumped in order to loose weight.

@@j.sanchez187 or to anyone with a diesel engine or a kerosene heater.
Not a story. Smaller planes like the A320 and 737 which can’t dump fuel are by far the most used aircraft. They outnumber all other planes combined by over 2 to 1 in airline fleets
Don’t watch this watch captain joe
T7's Aviation yup
But I never run out of jet fuel.

Outstanding video.
On September 2, 1998 Swiss Air flight 111, which was an MD-11 aircraft, crashed off the coast of Nova Scotia killing all 229 passengers/crew on board because there was smoke in the cockpit and the pilot chose to fly out over the ocean and dump fuel rather than land immediately. Sadly that was the wrong decision.
The airplane would have been crushed.
Actually if you look it up, investigators believed that even if they had attempted to land immediately, the plane would have still crashed, due to the severity and heat found in what was left of the wreckage. You can also refer to TheFlightChannel's video on the crash
Most likely would have die either way. The plane was quickly in flames. That's the worst thing that can happen. They couldn't have landed, in one piece, with all their fuel. They made the right decision by following the safety procedure in place at the time.
It made no difference in the end
Well the chance of crashing from not dumping fuel are much higher compare to the chance of die from the smoke. This is just one of those unlucky attempt
4:21 wow my phone just got 7g's, Excellent service.
No matter how heavy jet fuel is, IT CANT MELT STEEL BEAMS!
This one time they had to dump fuel into the ocean because a passenger had a problem with a moana blanket and became unruly
Thanks
*peeing airplane*
Showing the autopilot panel for fuel planning?
I wasn’t actually expecting that answer
We use to have a DC-10-10ER and on a ferry to USA the crew had to dump approx 40K pounds of fuel over the English channel to make an Emergency (two engine) Landing in Stansted UK. I got to watch it being jettisoned out of the end of the wing like a fire hose!!!!!
There was an a380 (QR905) that was flying from Melbourne to Doha, it flew over my house and I watched it fly circle over the ocean. Apparently there was an issue with the landing gear right after take off and had to get rid of all the excess fuel. It took more than 3 hours for the plane to land safely back in Melbourne
Nice Animation on those stairs
Maybe in the future we could store fuel in several separate tanks that are shock proof, fall proof, and leak proof (maybe also equipped with parachute) that when they want to dump fuel they could just drop some of those tanks as necessary and later those tanks can be retrieved and used again.
0:52 5000 gallons of jet fuel. 1 gallon weighs about 6.8 pounds. That's about 34,000 pounds in fuel alone!
Sherlock
They dump gas so God can cook his steak in heaven
Good. He was getting jealous of Jesus’s lines of coke.
It sure doesn't dump thousands of pounds per second. The 777's fuel jettison system takes roughly 30 minutes to dump from a heavy fuel load (130 tons) down to max landing weight, and it varies the dump rate to respect center-of-gravity limitation while all that weight is being moved around. It also leaves about 1 ton above max landing weight to account for your fuel burn on the subsequent approach and landing.
We're trained to aim for max landing weight if time permits, or if not, 300,000KG works for an overweight landing. The landing gear can take the 'abuse' if needed, as in the case of a critically ill passenger.
Great content 🔥🔥🔥🔥
A spark would make a fantastic trail!
The design is based on maximum landing weight. And the regulations are very detailed. As the professor said in a inflight emergency all bets are off and if a overweight landing is done then so be it. Landing overweight can also have the potential for structural damage reduced by flying a much shallower approach angle and controlling the descent rate. Basically you are very gentle on the throttle and flight controls and very very carefully monitor the approach speed and angle.
It is also possible that some aircraft will need to burn off fuel but that can take a very long time especially with heavier international flights with not only heavy aircraft but heavy fuel loads. That’s when the question becomes of whether it is a emergency after all. You can circle several hours burning down to max land weight especially if there is no fuel jettison system on the aircraft. There will be many questions and lots of paperwork to fill out so Captains are very cautious of this fact. Some are no brainers like fire, loss of engine and some medical issues. Some are not quite so much. In the case of a heavily fueled international flight the problem itself might not be an emergency but the restrictions for the scenario might be DO NOT Enter ETOPS airspace. That restriction is common due to the potential of problem getting worse and being in the pre-verbial...”No Mans Land” between the oceans. Even though the aircraft may be certified for flight with loss of engine or system that scenario is based on the problem happening while I. The middle of the ocean. If you haven’t entered the ETOPS and are on either side of the ocean (Atlantic for Example. If the problem develops in the middle than fly to either side and land. If you are not up to the ETOPS area yet most airlines, aircraft manufacturers and regulatory agencies prefer you not risk it. Yes you can spend five or six maybe more hours holding offshore of the origin country and wind up back to the original airport where you came from. Depending on the airline and logistics it might be better to return back to origin airport.
Example a British Airways flight from London to the US having a problem might elect to return to London for repair and passenger accommodation. The same scenario for United or Delta flight leaving the US for Europe might elect back to the US origin airport.
When you are passed what is called the Equal Time Point then you are pretty committed to one side or the other. ETP is the point where it is the same amount of time and distance to go back to Landfall whichever side you are on. Note I said landfall which basically means a runway suitable for that aircraft. It might not be origin but a safe landing airport and runway. A Lufthansa flight from Germany to the US might divert to Ireland. A United flight to Europe might divert to Canada or the Maritime Provinces (Gander, Goose Bay, Halifax etc. This doesn’t fix the problem but gets the aircraft safely on deck then worry about the passenger accommodation....Rescue flight, return back to US/Europe etc...
would it be possible to prevent landing overweight in the first place? like stronger structural elements + prevent overloading?
Jet fuel smells good in the atmosphere.
$20,000 of fuel dumped into the environment, in the name of potentially saving the life of a 60 year old?
just doesnt make sense in my book...
If that was your mom what would you do?
@@jaedenmarsh1156 they also said that 2million gallons a year a dumped... thats a lot. sure its not always for some grandma, often i'm sure its because of weather. but i'm saying a 60 y/o grandma with health problem is no reason to be so financially wasteful and environmentally destructive.
and yes, if it was my mom, i'd have the same feelings; if it was me, same deal. human life is not that precious - our planet IS.
I thought there was the deal where it takes longer for the plane to stop when too much fuel is onboard. If it takes longer to stop than you have runway for, that is bad. I remember the documentary on the Quantas A380 uncontained engine failure mentioned one of the flight crew calculating how much runway they needed to stop the plane as they were fueled up for a long haul flight and they needed a long runway to stop with their heavy fuel load. I remember hearing they stopped within 100m of the calculated distance. For example wouldn't want to land at Midway airport in the Chicago area, especially in the winter time with an overweight plane. The last time I landed there in the winter time the pilot gruffly plopped the plane down at the outer edge of the runway after a steep descent with the speed brakes on (barely flared at all), then took the whole length of the runway braking hard with the thrust reversers roaring like I have never heard them roar before only to make a sharp, fast turn at the other end of the runway before slowing down the rest of the way. Especially a place like there if it takes longer to stop because there is too much fuel on the plane, you are just going to slide off the end of the runway. (And planes have been known to slide off the end of the runway there, at least in the winter time.)
Yes... that was Qantas flight 32 out of Singapore. The crew did a good job to land the aircraft safely will all onboard but more credit must go to the Airbus A380 engineers and designers who created an aircraft capable of withstanding such a catastrophic engine failure and landing safe without it losing control, breaking up and falling from the sky.
Anybody know the song at :30
Everybody gangsta untill they realize the tank are empty..
That explains why it rains even without clouds in the sky
plot twist: the dumped fuel is really all your crap in the aircraft lol
Yes omg 😱 I just thought of a great idea!!!!
The Fuel Cost: $20,000
A Life costs: $6M-$10M
Lol good timing
Air planes: Dump fuel
Covid:
what was the flight the women was on in 2018?
Just something to add here... when someones sick or something, pilots don't think about fuel dumping right way. They need to find a suitable airport first and then think about fuel dumping
I witnessed a Boeing 737 dump fuel via the NACA ducts over Balboa Park at low altitude just after take off and it did not do a return to runway. Facts straitened. Its still a fuel dump pups.
Boeing 737s cant dump fuel by pilot control. What you saw was fuel spilling out through NACA vents from the surge tanks. Not dumping fuel persay.
United state government: did someone say dumping fuel?
JetA costs like $5 a gallon that is extremely expensive and ineffective. So ya you're correct.
Why not just dump the plane and let the passengers just parachute back down to earth 🤣🤣
The reason plane crashes are 95% survivable is because most are minor incidents on take off or landing. The classic shit-goes-way-wrong calamity you imagine when thinking of a dramatic crash is nowhere near 95% survivable.
I’m curious about what would have happened on 9/11 when all planes were forced to ground. Did they dump? Did they land heavy? It must have been a feat to accomplish that.
I heard on the radio, a plane recently dumped fuel over a school near LAX causing numerous breathing problems between staff and pupils, that's not good at all..
Pilot certainly haven't better option in given moment, so had to make less painful choice.
Just imagine you having a normal day and all of a sudden a shit ton of fuel falls from the sky
That's never going to happen since planes moving very fast so the amount of dumped fuel scatters
Imagine standing under that with a lighter on

"EPA isn't worried about it" as the EPA guildelines regarding fuel dumping are (at least in part) written by the aviation industry.
What if someone requested a Mcdonald drive thru during mid flight?
Yeah... why not get the passengers to drink the fuel to reduce the plane weight.
Saudi Arab gonna love it.
No wonder my plane likes to think that it’s a beyblade
Safety comes first. Even if it were illegal if the pilot could justify it for the safety of the aircraft they likely wouldn't get into trouble with the FAA. As for their airline that's a different story. That $20k in fuel may have been picked up by an insurance company but it may have also just been eaten by the airline.
Cool good to know

...well, they’re not gonna dump whale oil now, are they?
Flipping, and then forgetting I flipped the dump switch is just one more reason I could never safely be a pilot.

If a plane is grounded for inspections because of a heavy landing it’s going to cost a lot more in distributions then dumping fuel.
OHHHH THATS WHAT THE TRAILS ARE
How does Boeing know? 🤧

They're barely flying now
Even with cessanas and twin otter
i saw a dump ignite. fireball 50x bigger than the plane, happened sydney australia mid nineties, never heard anything about it
Yeah happened from time to time. The plane was a military F1,11. Little airshow thing they did from time to time called dump n burn. It looks awesome. Perhaps you looked in the wrong part of the paper. Instead of the shock / horror bit, you should have looked at the footy grand final bit.
Yet if my car did this the fines would be astronomical.

Good example of human right going before money in this case, to bad this isn't always the case.
It isn't the airlines job to save passengers that know themselves they are an extremely high risk and still take the chance.

Put a rocket engine at the back of the fuselage that is modified to burn jet fuel. Burn fuel faster and get there quicker. It’s a win win
Make another video on why planes spray aerosols into the atmosphere to modify the weather...Geo-engineering!!
Don’t waste our oil, it’s expensive yo
Make a capsule for it
rather silly to be perturbed much by fuel jettisoning.. when.. till not so far back in the past.. even dumping "dump" (human waste) wasn't really banned in the strictest sense.
because if they land over Maximum Landing Weight then the aircraft will be grounded for a long time as thorough inspection needs to take place. Many airlines rather dump fuel than to lose revenue like this as long as there isn't a risk of fire due to the emergency.
Not really, airlines actually lose revenue dumping fuel if you rewatch the video.
They say rare occasions , but every time I look up all I see is the fuel steaks in the sky
This is because of the temperature difference. It is much cold at higher altitudes and therefore the hot exhaust gas produces the streak. Imagine if you were to blow out slowly on a cold day.
Contrails. At certain altitudes and certain conditions, any airplane leaves condensation trails, visible in WWII shots of planes that didn’t have jet engines or fuel jettison. If you’ve ever seen what looks like a drop of rust on your car that just wipes away, that’s jettisoned fuel.
I see a plane with a white trail behind it at least like once a week
i wonder how companies like southwest can still make money if theyre dumping so much fuel.
even having to pay all the workers there.
