Why Pilots Dump Fuel Before Landing
HTML-код
- Опубликовано: 29 авг 2024
- Picture this: you're nestled cozily in your window seat on a jet airliner when suddenly, you notice weird white spray coming out the back of the wing. Is something wrong with the plane? Are you going to crash? No need to panic! At this moment, the pilots are performing a standard procedure called fuel dumping.
Btw, it's by no means cheap. For example, a mid-sized Boeing 737-300 uses about two and a half tons of fuel per hour of travel. The price of jet fuel is more than $600 per ton, so that means that while flying such a plane, you spend approximately $1,500 per flight hour. So why do they do that?

SUMMARY:
- Most planes must be lighter when they land than when they take off, like more than 200,000 pounds lighter!
- If a plane doesn't use a certain amount of fuel before landing, it might hit the ground too hard, which can lead to some serious damage.
- From time to time, emergencies occur, and planes are forced to land way earlier than planned.
- Few people know that most fuel is stored in the wings of an aircraft. That's why, when a pilot flips a switch in the cockpit, a sophisticated system of pumps and valves comes into action, and special nozzles in the wings let out excess fuel.
- On the other hand, not all planes have this complicated system. For example, narrow-bodied planes like the Boeing 757 or Airbus A320 can't dump fuel.
- But if the plane's construction allows it, pilots prefer to eject fuel rather than to risk people's lives.
- Most fuel evaporates while still in the air and never hits the ground.
- It may seem terrible from an environmental pollution standpoint. But here’s one bitter truth: one way or another, when planes fly up there, all the fuel ends up in the atmosphere anyway.
- By the way, every plane must carry more fuel than is necessary just to cover the distance from point A to point B.
- On December 29, 2014, Virgin Atlantic Flight VS43, bound for Las Vegas, took off from Gatwick Airport. Shortly after, the pilots realized that the plane's right-wing landing gear had gotten stuck and hadn't retracted.
- After circling for several hours, the pilots finally ejected enough kerosene over the territory of southern England to return to Gatwick.
- One of the reasons for locating fuel tanks in the wings is to lighten the aircraft's fuselage, which reduces the pressure on the wing roots.
- If all the fuel was stored in the nose or tail of the aircraft, the center of gravity would change along with the fuel consumption, and it would mess with the plane's stability.

Thanks for answering a question I didn't even know I had.
Look for captain joe, Mentour pilot, and 74gear. They're pilots and have RUclips channels with lots os fun videos for aviation enthusiastic
@@joaquimgoncalves9412 i watch captain Joe
@@nonenone5326 Yeah this info is fake
The truth is for the fuel:
Its called the jettison procedure
The way fueling is:
Block fuel
Taxi fuel (in and out)
Trip fuel
Alternate fuel
Contingency fuel

@Ethan Lincoln Bendijo its "you're" not "your". Guess you're also not there yet
Yeah me too

@@Vaderist. so you're telling me "its/it' s" and "your/you're" are same kind of mistake? What a big brain you must have! 🥴🥴🥴🥴🥴🥴
Labib Chowdhury yes i indeed have a big brain UwU
I don't know that I'd describe this as a "standard procedure," exactly. Fuel dumping is unusual, and many commercial aircraft don't have the capability at all. Generally only the largest aircraft have the ability to jettison, and it rarely happens. In all the years I've been an airline pilot I've only dumped fuel on two occasions.
GlobeTrodden he literally says all of that in the video
@@knuffelbeer193 the commenter @globetrodden is referring to the fact that even though it isn’t common the volume that we see in the skies don’t account for the amount of that we see on a daily basis.
2:32 why are there wings on each window
Because it's a hologram
It’s the new AiRbuS A420
DCD11MC lol
So that you can see the hairy creature tearing at the wing like on the Twilight Zone 👹 ✈️🛫🛬🛬🛬🛬🔥
Lol yea
I found the voice over so calming and convincing that I was ready to dump my car fuel too😂😂😂😂😂😂😂😂😂😂.
2:33 when You're holding up a sign saying help! And your smiling...
Haha lol
I had no idea fuel was stored in the wings or that it was being released at times. Thanks Bright Side, always learning something new with your videos
SVT it’s where ever the fuselage is
lol your learning something but not very usefull info tbh alot of it is wrong i wouldnt thank soemone for giving me false information

I didn't expect that Jet fuel is so cheap. It's so much pain to refill my truck tank 😅😅😅
Well considering that airlines have to buy 40-80 thousand gallons of it per flight…
Dumping fuel is not a standard procedure! It´s in an emergency only. And fuel is dumped, not ejected.
Ahamay2012 We often dump kerosene at our pig farm, into local streams. Much safer than igniting. It naturally evaporates.

I never even realized that planes did that until you said that
I love when my blocks are flying (like all Numberblocks)
Got recommended after a teacher sued an airline for dumping fuel over the school
Did the fuel land on the school?
Yeah. Did anyone get wet with fuel? Lol
Laura Kelly the New York case in wich united did it
2:22 a plane with 3 wings, impressive
😂😂
6 wings plus with tail
@@adzinagg6987doesn't count , the tail is a vertical stabilizer, the back also doesn't count as wings , its called horizontal stabilizers
I work on aircraft for a living, and once saw a misfire of the jettison system (fuel dumping system) inside the hangar on a 777-200. It hit the back hangar doors. Needless to say, that was one big clean up operation.
No wonder sometimes I think it’s raining then stops 3 seconds after
Lol
Thats called a micro burst, lol
@@mjstafford758 No, a micro burst is WAY different
Doge Smoker what s it

Dumping fuel in the air now i realized maybe that a one cause of big bush fire in australia during summer ..
Nuh thats not ..
ZEENKE It evaporates before it gets anywhere near the ground
You must not listen well
I saw them dump fuel and I also watched this video for that answer.
Thank you bright side!
I never knew a plane dumps fuel in the air. Thanks so much for the knowledge
I always believed that the fuel is dumped in an emergency so as when it lands it won't catch fire
Daniele Pelaia if that end if the plane is too heavy on landing they’ll dump fuel they don’t just do it because they feel like it’s very rare
I guess that’s how the amazon forest was in fire... fuel and something ignite it... it burns
It naturally evaporates before a fire can even start though
Nice video!
Video - Fuel dumping is not a commonly performed procedure.
Me - Why recommend me this RUclips?
Planes don't dump toilet water outside.
They store it in tanks which are emptied.
Plz don't compare planes with Indian railways 😂
@Prranjal Shrivaastav
People dump waste in toilet too, imagine something small & hard dumped by a plane 500m above ground hits a person.
Obviously it'll be an issue
At 1:56 and also at other intervals, u make us to watch that fuel consumes from center tank first and then from tip of wings. But actually, aircraft consumes fuel first from tips and then from center tank to maintain C.G and C.P of aircraft. But overall the video is good and it provide basic info to beginners in field of aviation
I saw a bird dumping USED fuel
Lol
2:34 look at the windows 3 wings...
Technically 6
ye
Imagine the amount of fuel dumped in the episode of Mr Bean animated series where he do a treasure hunt of a puzzle piece
yes i saw fuel dumping from ground.. but i thought.. engine need servicing just like our motor vehicles. but now i know the fact.
thanks
The truth is for the fuel:
Its called the jetison procedure
The way fueling is:
Block fuel
Taxi fuel (in and out)
Trip fuel
Alternate fuel
Contingency fuel
Final reserve fuel
[Upon pilots request, extra fuel]
Also if you go over the runway, its called a runway overrun.
you right jettison system
Never knew they dumped fuel thanks for this video.👍🏼💕🌷
I love you guys and always remember stay always on the bright side
If you see fuel coming out collect it and sell it.😂😂
The thing is I always thought it was electricity getting out of the cabin after a thunderstorm thanks for the answer!
also something else too
You give the impression that the inability for smaller jets to dump fuel presents an inherent danger but they simply don't need to.
In simple terms their max takeoff and landing weights are close enough that even an overweight landing in an emergency can be tolerated safely although there will be a thorough inspection afterwards.
Even larger aircraft like the A330 or 767 may or may not have fuel dumping capabilities depending on options
So many issues. For one, jet fuel isn't gasoline. Also, dumping fuel is a very uncommon procedure.
Yep... was crew on a military flight. Full load of fuel. Developed a problem on the climb out.
Only option was to dump fuel down to a safe landing weight. We still landed slightly overweight and the aircraft was immediately taken out of service for inspection.
As an aside, most airports will have a pattern/area for aircraft to hold/orbit if they have to dump fuel.
8:26 But hey now don’t go dumping your fuel now. 🤔
Your voice is amazing.
Dumping fuel is a very rare incident. A pilot can fly a whole life without ever dumping fuel.
@ Fuel dumping isn't very common as the only time it is used is for emergencies where the airliner need to land early. Yeah you flown your whole life but you probably never been on a plane that had to dump fuel, as a high percentage of flight are are successful
Thank you for telling me that why other airlines land normally and why Ryanair doesn’t
My self know that, why they do dump fuels coz i have experienced with aviation. However this is very important video who really don't have any idea about fuel dump...
i dont agree the video has alot of false information you can go watch captain joe, 747 gear, mentour pilot etc. they are real pilots and they explane it was better
"But heyyy.... " haha I love the intonation.
Me coming in to this video: They do that?
Such an important thing I got to learn today
I'm not FIRST.
Not even LAST
But when BRIGHT SIDE uploads i'm pretty SURE.
That I will click it FAST! 😤
cool rhyme
Congratulation for 40 million subscribers. Your videos are awesome.
The video is wrong. Planes does not dump fuel during the flight. Levitation fuel is only consumed 80% of the fuel for take off purpose only. How it works is the fuel is filled in both wings and it's not a jet fuel, they are using rocket fuel in both engines. The rocket fuel is mostly liquid hydrogen which makes the plane easily take off from the runway, so pilots uses the term levitation fuel. Without levitation fuel, the plane will not be able to get off the runway into the sky. During your midflight travel from one city to the next, the plane is already on reserve fuel and consumed only 5% of the reserve fuel to make it to the next airport for them to land. That is why you don't see fuel dumping during your midflight and landing.
Also, the video states certain information, some of them are inaccurate. Wings do bend during midflight travel which is why wings don't break. There is nothing about dumping fuel to make it lighter, the plane is already lighter after take off from the runway due to levitation fuel consumption.
Finally, the plane's wheel are not impacted by the fuel. It doesn't matter if the plane has 80% fuel left, the wheel is fine regardless of the fuel intake. Wheels are made by different parts that doesn't break the wheel and its legs, it has nothing to do with fuel.
If you are wondering about plane, do your research before you come up with your results before you make the video and this video is not cited properly so the information is full of inaccuracies. Always cite your work when doing the video on RUclips.
🥺I appreciate the truth!
Well said sir. You're an Aircraft Mechanic or related to aviation industry?
@@kinoadriangonzales6260 No. I flew on plane many times and I know those things.
@@pantherzone2008 Oh. I thought you're in Aviation Industry. 🙃
you played too muck ksp
Till now I was not evening knowing the fuel was stored in of its wings 😂
Thanks bright side for the knowledge 🥰
6:02 that’s not an 747 that’s a *A340*
I do see it everytime with my connecting flights, thinking that the plane is just performing a cloud seeding procedure, but that was completely a myth. But hey BRIGHT SIDE, thanks for this video, I learned something important about fuel ejection of airplanes at flight. 👍👌
What you see isn't the fuel dumping
2:21 how many wings does that plane have😂😂😇
It's a plane from 2040!
That many wings: Yes
Factory: how many wings you want?
Airline:Yes
Dear god, the real question is with that many engines and several wings, how fast? 😂
DetroitIsMyDaily OMG🤭🤭
Thanks for reminding me things i learned from flight sim
We noticed mystery oil spots on our driveway and autos. And planes have been rerouting over that area. SOme people have called them chem trails. NOW we have our theory documented. THANK YOU
That's always good for the air
Hmmm Not plane but I Dump My Fuel a lot in the Mid Air..😂

How do you say its not boing airbus ?
I was talking to a farmer who had a cornfield close to a major airport. One day, while inspecting his field, he found small yellow dots all over the leaves of a large swath of the corn. He was in his 60s, a lifelong farmer, and had seen just about every pest and crop disease around, but had never seen anything like this. He asked around to other farmers to see if they had any ideas but came up blank. He eventually called the Ohio State University's agricultural extension office in his county, and an agent came out. It turns out an aircraft had made an emergency landing a week or so before due to a medical emergency and had to dump fuel. The altitude they did it from was too low for the fuel to entirely evaporate, so droplets ended up drifting down onto the leaves and causing little pinpoints of damage where they hit. He said he thought he'd seen everything, but that day proved him wrong.
7:22 weird flex but ok lol
Maybe next you should do a video on why there’s wheels on an airplane.
I'll save u guys some time, it's harder to land a plane with all the extra fuel because it makes the plane weigh more.
Video explained in less then 2 seconds
Commercial jets also have center tank(s)....the fuel is not just stored in the wings.
*most* of the fuel. Lots of planes have a tank or two in the fuselage, but the size is minimized to conserve baggage space.
I live in the flight path to LAX, and notice this happening from time to time with some of the planes.
I'm a student learning and training to be an aircraft mechanic and there is a lot of fascinating facts you never knew where happening while in flight
My dad has dumped fuel on his way to Honolulu once
No one was happy for the vacation delay (he was the first officer)
Awesomely animated
I liked ur video,big fan of urs bright side
TEKKING GAMING this channel it mostly has quite a bit but at least this one is kind of right
i have seen fuel pouring out of the wings on take off
People below the airplane:Why is it raining fuel?
No, I've never seen, but I'm glad now I know why.
Another great video from Brightside.
Me opening the window because is hot
Everyone else in the plane:
: 😱😱☠
You can’t even open the window you have to break it open

You can get succed out
You make amazing information videos!
Answer: so then they don’t cause a fire and big plane explode
That's what I thought.
Victør that's what I thought
Agata Malecka lol I didn't even see you say the same thing until after I said it But lol
Now I know why that rain tasted weird near an airport I was at
He’s my fav voice who else ?😭
I've learned many new things today.. Nice video
That’s why tickets cost so much, they dump thousands of gallons of fuel
no its not because of that its becaus jet fuel is expensive they dont dump thousands of gallons fuel dumping inst very common
Very informative. Keep going. 💪💪💪
Who else went to look up videos of plane dumping fuel after this video
me
Jameson Bobbert
I have one on vhs where we dumped full tanks 10 min after takeoff over the great lakes
i always thought this was myth good info 👍
YEAH I SEE ID FROM AN MY JOURNEY TO QUATAR I'M EXPECTING A REPIY
you saw a fuel dump?
sure cuz its not very commen it may be something else too so its a very low chanse its actually fuel dumping and did you land at a different airport cuz if you dumped fuel you probably landed at a different airport and in tht case your pilot would do a PA about the situation and tell the passengers that they cant go to there destination because of an emergancy did these things happen?
Now I know. No need to worry. Thanks
its dangerous when throwing fuel on the sky
@@mgsaviation9292 its dangerous for living things in ocean too
@@mgsaviation9292 so you must know exactly of what ocean you've dump the fuel so you can put that so called bacteria to remove them though
@@joanapotvlogs yup i was flying to Zakynthos turtle island thats protected by goverment and the pilot started to dump fuel...
@@mgsaviation9292 I was flying with Smartwings which is Budget airline xD
Crashing a plane is more dangerous
I watched a plane dump oil (fuel) in the movie 'Flight'. Never saw one in real life!
Title is misleading, or clickbait if you will, you make it sound like pilots dump fuel before each and every landing when the truth is that its only done in an emergency..
Or from poor fuel planning or if the flight has a stronger than expected tailwind.
@@researchcapt I guess thats really rare, Ive never seen that case
Very informative. Thanks
1:11 I am beginning to think that no one cares what planes do to the environment
peoples in my country thought its a space craft because its fuel path, but after i watch this i can explain to peoples in my country especially my friends and my family
Who else noticed when he said captain kirk 😂
I love the bright side sooooo much they taught me a lot of w
2:21 explain those 3 wings.
This is something new to know
The guy that dropped his cigarette by the airport

The Rino Channel Gaming it evaporates before it gets to the ground
3:45 omfg it just exploded when it touched grass lol
I've only seen it once despite flying over 1,000 times.
6:58 each window has a separate wing for itself? Dayum😂
Some country with oil exist:
America: IT'S MY OIL NOW FOOL!!
also America: dumps fuel because it's too much for their airplanes.
Its interesting...that about fuel dumping
This must pollute the earth so much.
Does it go on people.. or the fuel just lands on the runway or...?
