De-Icing the A380

[deorasta]

the best job ever!



[yoDog421]

spray me next!!

[emiratesA380NCL]

was this dubai :P

[danimart85]

That's the best reason to fly in Nordic countries during winter! They don't have any trouble on de-icing!

[89Anees1]

Where is this???

[barthoedemaker]

why don't they use bigger pumps and spray nozzles..job done much quicker

[hyrrokinfamily]

I guess there's snow rectangles because of a hot liquid in the wings ? Hydraulic systems ?

[weetnietgeen]

@hyrrokinfamily exactly :) also electrical cables and stuff

[NextLvlProductions]

From Heathrow to ?

[1982FMJ]

it do wonder how much exhasut fumes or contaminted air are aircraft cabins contaminted with on flights. THe ground air supply system is often the worst in smell. Then again maybe its not that bad. I have not heard about much research done in this area. HAve nasa done research and tests into cabin air quality and tested the levels of contaminants. Are the results so shocking that they don't inform the public. THe passengers lungs probably asorb the worst of it helping the pilots lungs

[flyboy21141]

@1982FMJ okay... jet liners have extremely dense cabin air filters which make sure the air quality meets FAA regulations [VERY strict]. when cruising, the cabin has a steady oxygen flow enriching the air to keep passengers comfortable. the ground air supply is used when the engines are off, and bleed air intakes are offline, to keep the air conditioning systems of the aircraft running.

in short, the air inside your house is probably many times more hazardous than that of an airliner. ..

[1982FMJ]

@flyboy21141 its still crap

[1982FMJ]

@flyboy21141 be honest have you carried out any scientific research or analysed cabin air? if not then what you are saying counts for nothing.

[flyboy21141]

@1982FMJ uh well. i have a pretty decent understanding of aircraft systems, flight dynamics, procedures, etc, for i have flown an airplane from takeoff to landing before. i have stepped into aircraft cockpits and asked pilots such questions. and i have spent countless hours watching air crash documentaries. have you? if not, then right back 'atcha. also, again, there's an entity called the 'Federal Aviation Administration" that governs such things. look them up yourself.

[1982FMJ]

@flyboy21141 that doesn't mean cabin air is good for you still. you seem to be under the impression that cabin air quality is good.

[weetnietgeen]

@1982FMJ it can be good, but as i've learned, most airliners let the pilots use only 2 out of 4 aircopacks which means fuel economy but less healthy air... if you want the kind of air you breath on the ground you'll have to use atleast 3 packs but for the best result you'll have to use all 4 of them, but using all 4 means alot of fuel consumption and thus means more pricy tickets to pay for the extra fuel that has to be carried extra ;)

[1982FMJ]

@flyboy21141 Also most airline pilots are not really sure waht the long term health effects of cabin air might be. Remember that some passengers put themselves at more risk and fly long routes more often that pilots do. Pilots stick to the health and safety limits of how often they can fly not only for safety because they are flying but also as it is not reccomended to fly long haul every day like some bussiness people do

[TruthfuLie]

At what rate is the Icer-man paid (in pounds) to de-ice such big birds?

[mupsilaama]

The snow is in rectangles, because the wing has ribs and spars inside of it, that stays warmer than the fuel. The fuel is free like in a soda bottle, so the skin is cold there, where there aren't any ribs or spars. The temperature when flying is -56C, so the fuel will remain freezign even if the temperature on the earth is warm. And ofcourse metal will warm up pretty fast.

[slatestriker]

hes to far away from the plane to be truley effective you need to be at least 3 to 5 feet away from the surface that you are spraying

[bruno170397]

I think Its Water!!

[bagelboi66]

@slatestriker yeah that must be why it crashed.

[keduardop]

what is it that they spray?

[aviationfan6776]

SPRAY THE WINDOW

[tierren]

HEY THATS ME !!!!!!!!!!!!1

[TheRockstars11]

VI route V2 Posative rated climb gear up

[jjry222]

tis true. it is illegal to take off having contamination (ice, snow, sleet etc) adhereing to the planes surfaces.

and you always de-ice the entire wing... and you do it symetrically on the a/c

[grooveclubhouse]

hey buddy! you missed a spot! the whole wing man! i see someone was asleep during the ice identification training vid. lol

[greenmaker25]

you dont deice the WHOLE wing.. there is not need to. lol u deice the parts tht move.. hence wht he is doing!! :)

[SurpriseItzDJBen]

...do you want people to die?.. lol.

[tickle2012]

I can urinate and de-ice quicker than that....

[grzesieksz]

llllllllllllol

[gurubaba95]

put in some music it would be great because its really very quite when the engines are not running

[syafiqpilot]

hey will there be snow in london on the december?

[jasleil]

ｈａ　ｈａ

＂Ｃｏｍｅ　ｏｎ　ｓｈｏｏｔ　ｍｙ　ｗｉｎｄｏｗ．＂

[helreaper]

the companey who de-iced this A380 did not and still dont have the right rigs for the job it took them over 2 hour to de-ice the plane and all the other companeys did was take the piss out of them at the moment there will be only one companey in LHR ready for de-iceing the A380 when the EK one comes in and the reason we at LHR dont have fancy drive through spraying is because its never that f**king could her to have one

[kuyakev]

would the a380 be able to takeoff if it wasnt de-iced?

[gurubaba95]

nope it wont take off because ther would be snow on its wing and important parts example if there is ice on the wing there would be now air flow.

[Donz5885]

All the aircraft need to be de-iced first before take off. That's on first priority because the ice could disturb airflow on airliners wings.

[Mjws2907]

Possibly, but the main reason to de-ice it is to clear the control surfaces of the a/c, you don't want to take off and find out you can't turn because the ailerons are jammed because of ice.

[floatplanepilot2]

Wrong, you de-ice the entire wing because frost the consistancy of sandpaper can cause 30% loss of lift and a 40% increase in drag. It is illegal to take off with ANY frost, ice or snow on any part of the wing.

[Mjws2907]

He asked if it were possible for the A380, and loss of control surfaces b/c of ice is a real danger, but yeah, I didn't think of drag issues, it being legal or not is not in the envelope of the discussion. But since you're the expert, could the A380 take off with it's T/W ratio, 30% less lift and 40% more drag?

[muhuskerfan32]

@floatplanepilot2 light frost on the underside of the wing from cold fuel is legal to take off with

[phobal]

@floatplanepilot2 It's illegal to take off with CONTAMINATION on the wing. However, you can take off with snow on the wing if PIC is convinced it will blow off.

[1ohtaf1]

yeah but the ailerons or flaps wont jam as easy as the wing lossing lift from the ice or snow.

[biggestMetallicAfan]

What???

NoNoNo, you de-ice because the ice disrupts the smooth airflow over the wing, decreasing lift like crazy, and making a hell of a lot of drag.

[bazman85]

thats a totally shit de-icer, you should see the things they use in amsterdam, you'd think a big airport would be better equipped.

[Sokamok]

I would recomend a Vestergaard de-icer. Much more sufisticated and relyable.

[filiremix]

Hehehehehe i just pressed the block user button :P

[filipinoboy147]

lol xD

[sidhanthmelvani]

I suppose the white stuff on the plane's wing is snow? Why is it in rectangles?

[filiremix]

Yes, it is snow, but i have not got any idea as to why it is rectangles, sorry.

[dru4m]

Assuming the A380 uses engine bleed air for heating like other jets, the rectangles are probably from the ducts in the wings used to keep the fuel warm, just a guess.

[crazyshanerboy]

@filiremix it forms like that becuase of the fuel cells in the wing get super cooled and the ice forms where its coolest

[gudskyld]

@filiremix Quite simple, the rectangles are the part of the wing that is hollow, so the air in the wing cavity is cooler than the temp of the ribbing, allowing the snow to remain. The lines in the snow are above the ribbing, which is made of aircraft aluminum--an excellent conductor of energy (and heat), thus conducting the heat of the aircraft out to the wingtips. So the snow over the ribbing melts.

[gudskyld]

@filiremix Quite simple, the rectangles are the part of the wing that is hollow, (gas tanks or other) so the air (or fuel) in the wing cavity is cooler than the temp of the ribbing, allowing the snow to remain. The lines in the snow are above the ribbing, which is made of aircraft aluminum--an excellent conductor of energy (and heat), thus conducting the heat of the aircraft out to the wingtips. So the snow over the ribbing melts.

[Tommiclio]

@filiremix My guess is heat....the patches of snow maybe are where its less cold....

[Sven2Perroy]

@filiremix simple, the snow that you see here is simply covering the holes in the frame of the wing.. because making a plain wing would definitely make the plane unflyable hence the frame is designed with holes in it. with super solid and light material, you got no problems.

the fascinating things about engineering!

[aeroguino]

@filiremix I think those lines are the area that has wing spars and ribs underneath the skin, though i don't know how exactly they prevent the snow accumulation above the skin because I doubt that they have deicing functionality

[flyer737sw]

@filiremixThat is where the supports are underneath the skin of the wing. Since this metal is thicker in these areas, it is hard to cool to freezing temps.

[kryptoniterxn117]

@sidhanthmelvani it is rectangled bc snow melts on the warmer parts of the wing that is attached to the skeleton underneath. And so the unmelt parts (your rectangles) are just skin and hollow inside, the colder areas that dont melt the snow.

[jmister22]

Probably hot air from the engines flowing Inside pipeing inside the wing to melt the ice.

[Macky91SWE]

@sidhanthmelvani its in rectangles because the wing heat is on and it doesnt cover the whole wing just parts of it like on a car window (The small lines)

[poskyflyer]

@sidhanthmelvani the clear spots on the wings is right above where the wing heat is put to, not sure how its done on the a380

[TheAviationCenter]

@sidhanthmelvani There are metal structures that generates heat inside the wing structure, so it depends on how the heat flows inside... If the metal structure is one across each other, it will make a rectangle shape and when heated, it makes these funny shapes! So this is the De-Icing system from the aircraft, and the liquid that the man is throwing is Glycol! I hope I've helped you :D

[phobal]

@TheAviationCenter It doesn't look like glycol, it looks like water, which is ok for deicing if it's above freezing. Or this is a blend of 5%glycol 95% water or something.

[aircraftwiz]

@sidhanthmelvani Because the fuel took longer to warm than the solid stucture that braces the wing to you can actuly see the outline of the wing's internal struture... 3 years but somebody finaly solved it....

[iSOBigD]

@sidhanthmelvani The plane usually has fuel in the wings and it has many compartments...the warmer parts of the wing didn't have snow accumulate on them, so you get these nice shapes...

[TheJamesloy]

@sidhanthmelvani because of the fuel

[catalinghita]

@sidhanthmelvani because the fuel tank in the wing is honey-comb shaped, and the fuel is always colder than the outside temp.

[65Bubba65]

@catalinghita its a lie

[catalinghita]

@65Bubba65 ok, so it's not always colder, except if the plane is making a quick turnaround or the OAT is well below freezing, the question was about the shape of the snow spots, and those are determined by the shape of the fuel tanks in the wing

[itsthatguywithtwotoe]

lol ur both dickheds, and both is hassan.

nice vid, lol at the 1 de-icing machine part.

[filiremix]

Well if you are sad enough to watch it Hassan :D But thanks for the first comment on the vid. For that you earn a nice green thumbs up. See you at school bellend.

[thelastpharaoh]

john parry u nob takin a vid of a plane takin of MMMMMMMOOOOOOLLLLLLLLEEEEEEEEE­EEE
