I was a 757 captain flying a "redeye" trip from Las Vegas to Newark the night of the Millennial Changeover, with a New Year's Eve, December 31st 1999 departure, and a January 1st 2000 arrival. To make it more interesting, the airplane had just recently been delivered to my airline by Boeing, and had just 100 hours of accumulated flight time on it. It definitely had a very noticeable and distinctive "new plane smell" about it. So, the Millennial Moment with all the dire predictions of computer failures, and a brand new, relatively untried airplane under me, what could possibly go wrong? Answer, nothing. It was a completely routine and uneventful flight in a gorgeous, brand new airplane. I actually got paid to do it!
"But Russian manufacturers paint them in yellow. We're actually not sure why."
Well, since the only reason to spend the money and effort to make the yellow zinc chromate green is worker safety, I think you found your answer.
China painted their aircraft yellow too for the base color
@@jayjay53313 humans are replaceable…
same with azbestos gas masks filters, "we need you to live now, not later"
@@argonaut_aero So are you replaceable .
It's the primer and the quality of primer varies. A220 aircraft has a dark green primer and are treated with chemicals before applying it. Composite materials inside the wings are of different colour, yellow, due to fuel presence. The color difference is the chemical composition of the paint. In any case, the primer has many uses, all serve to protect the metal alloy.
Also, Alclad is "corrosion-free" because it's 𝙖𝙡𝙧𝙚𝙖𝙙𝙮 𝙘𝙤𝙧𝙧𝙤𝙙𝙚𝙙. Corrosion is literally the conversion of a pure metal into a stable metal oxide, and Alclad's "protective layer" is, as you said, aluminum oxide.
Yes, but not all stable metal oxides are corrosion resistant to the same degree as aluminum oxide. I don't recall the exact reason for it however but I think it was due to the hardness of AlO3 compared to others like copper oxide and also the fact that acid rain won't dissolve aluminum oxide but will dissolve copper oxide
Much like stainless steel
Just don’t put mercury on it…
(It’s illegal in the US to carry liquid mercury through aviation security.)
@@NickCBax dude who the fuck even has liquid mercury in the first place unless your a chemist
@@NickCBaxThat's not true. It's perfectly legal... to carry a mercury barometer or thermometer if you're a representative of a government weather bureau or similar official agency, or to carry a mercury thermometer for personal use in a checked baggage, as of 49 CFR § 175.10. Special conditions apply.
While black paints impact on the air conditioning is fairly irrelevant at cruising altitude, the UV light absorption and associated heat is not. Parts heat up and expand due to that heat, from either UV radiation or friction, then those parts change shape. That is why typically aircraft companies only allow white paint on Wings and control surfaces. You can design for the way different colors cause your wings to act, but it is much simpler just make everyone have white wings and make the airline figure out how to incorporate the white wings into the the paint design.
If you have the money to buy a private jet, you have the money to service it
We operate the only two black ATR72-500 in the world, there are no more wear and tear on the AC than any other color. It's rubbish. They get a lot of photos taken, though :)
Exactly what I was about to say. Alternatively Americans naked planes would suffer from the least thermal expansion.
Nah, the real reason aircraft aren't painted black is because American police would shoot it and sprinkle some crack over it
That's what they all say when they try and hide their racism😭

When I was flying international trips into and out of Japan, for preflight weight and balance calculations, we used 170 lbs average weight for each American citizen, and 120 lbs for each Japanese citizen. That was twenty years ago. I don't know what the numbers are now.

@@NotWhatYouThink I'm from the UK and once travelled around Europe (pre-brexit). I met lots of people and I remember some girls in Croatia asking me, while giggling, if everyone in Britain was fat. I was like nah that's America! Then I got back to England and all I could see was fatties all around me.
At least the video clip showed a hot chick, so I definitely wasn't offended at all.
I guffawed!
We aren’t all fat in the US
9:10 I see what you did there, and I'm appalled. That's TWO Americans, buddy! Give us the credit we deserve!
😅
Americans may be fat but you have to be able to tell the difference between 1 obese person and 2 fat people. It's basic algebra over here smh.
Depends on the age of the American. Usually the older we get, the heavier we get, but the rule is not hard and fast or even fat-free.
America must always be number 1
@@stormer9763 Somoa has them beat cold. The average person from Somoa makes an average American stop and go 'oh daaaaaaaaaaaaaamn', and the bigger ones often provoke a 'oh heeeeeell naaaaaaaaah'.
However, you can still blame America for that one though.
As a result of a trade deal, Somoa imports an absolute ASSLOAD of turkey butts from the US. Turkey butts are extremely fatty.
The SR-71 Blackbird, for example, was painted black because the color actually helped to radiate more heat away from the plane as air drag and compression heated it up to immense temperatures
Huh that's cool. I figured it had something to do with a type of radiation since they fly so high. Free particles or whatever.
I though it was a really dark purple?
@@fourdisconnectedcircles9386 no, pitch black
Technically it was not black. All the pilots called it the Habu not the Blackbird.
I have no idea who to believe in this conversation.
Just as an aside, it used to be (no longer sure if it is the case because it has been a while) that one of the primer coats on US nuclear submarines was yellow. Basically the same yellow that you see in one part of the clip here in the paint can. This got covered by a layer of adhesive and then the tile coating... but for a while we all walked around singing the Beatles song ;)
My favorite part was the C° 🤝 F°. I'm glad that they can agree on at least one thing. 11:43
The c and f scales are equal at minus 40.
The green on the exterior of Boeing planes is an acrylic coating that protects the skin panels during the assembly process. It gets stripped off prior to painting. All aluminum exterior panels are anodized, which forms a layer off oxidation that protects the top layer of each skin panel. Anodizing is used extensively in aircraft manufacturing.
It's surprising just how often airplane's paint gets stripped off and then painted back on
I work for an airline company just across the runway from American's Tulsa Heavy Maintenance facility, and I know a bunch of American Airlines A&P and engineering guys. They tell me that the reason American started painting their aircraft is because the carbon fiber body aircraft MUST be painted to protect the material from the elements. But American did not want half their fleet in one livery, and the other half in another, so they started painting all the aircraft to keep the look uniform across the entire fleet.
The UV light from the sun breaks down the epoxy resin holding the composite together. UV is much harsher at altitude where planes fly. It's already hard to predict the residual strength of damaged composites, trying to account for widespread damage for residual strength and flight safety would be more cost than it's worth. Better to paint it and prevent it altogether.
he said that in the video.
as for other comment, hyper cars run around with no coating. Hell the Toyota Yaris GR had a raw CF roof. So not sure how a super expensive 787 could be constructed with a CF epoxy that cannot handle UV.
@@Power5 It is not raw carbon fibre. It has a clear coat.
@@jamesrichardson645 yeah I remembered incorrectly. Been a while since I watched a video on it. It is a forged CF roof but then they wrapped it with a fake looking CF weave type wrap for reasons.
@@Power5 the difference of 30,000 ft of atmosphere. more uv gets absorbed
5:34 ahh yeah the world famous bomber the f4U corsair
And totally not the B-29
I thought the Aloha Air accident was due to repeated stress due to many more rakeoff/landing cycles that a short distance aircraft experiences compared to industry norms.
The green tinted coating on new unpainted Boeing aircraft is a temporary acrylic coating. The individual skin panels come already coated from suppliers. This is standard for almost all aluminum sheet metal.
The corrosion protection primer BMS 10-11 comes in both green and yellow. I have many pairs of jeans stained with the stuff.
you also have to paint CF because epoxy is UV sensitive.
and a lot of places you see "that carbon fiber" look, have extra steps to cover the CF in something not transparent to UV but translucent for visible light (which is more expensive than paint)
that or they make it out of CF, and then use a hydrographic water transfer to cover it with a picture of CF, so you think you are seeing CF, and it is CF, but your arnt actually seeing the CF.
Yep about the epoxy and UV
Former wooden boat builder here.
100% There are even manufacturing process control specifications that regulate when we can open doors and what type of light bulbs are installed in areas that produce aerospace composite parts. Raw exposed carbon is rarely left unprimed and relegated to areas of the inner structure that will rarely if ever be exposed to sunlight. If a part is suspected to have been UV damaged an acetone rub test is conducted where if the white gauze develops any sort of greenish black residue from degrading resin, the part will be rejected for assembly and scrapped.
8:00: That green coating being washed off is a water soluble covering added before transit from Kansas to Washington. It is not zinc chromate primer.
What gets missed here is that the carbon fiber re-inforced plastic of the 787 needs to be painted because it will degrade under the UV rays of sunlight, so that would be the reason you won't see pretty black carbon fiber planes.
I hate it when you're watching one of your favorite education channels on a topic you know a little bit about, and just see them get things wrong. Makes you wonder how much else they get wrong.
@@JeremyLogan yep. Same with news stories. I grew up in aviation and most stuff you have to take with a grain of salt.
That’s why I love the channels by actual pilots though. Just gotta pick your source.
Yep for the best accuracy seek the channels of actual professional pilots, scientists, doctors, historians. This channel speculates a bit, but it seems pretty accurate overall.
To be specific, Carbon Fiber is NOT affected by UV radiation, but the epoxy matrix composite used to bond it all together is.
Carbon fiber construction is not corrosion immune as suggested here. You are right that it is much better, but there is still a huge importance placed on galvanic corrosion. Carbon fiber is conductive afterall, so dissimilar materials can pose a huge problem. However, it is a big difference in the amount of money spent combating corrosion like you mentioned.
Galvanic corrosion requires different approaches to combat it though, so I guess it's a bit off topic for this video. Also, if you want to be pedantic, usually with galvanic corrosion the carbon fiber remains totally intact - it's the metal parts (like fasteners) connected to the carbon fiber parts that degrade, if the plane hasn't been constructed properly to mitigate it.
I made parts for Boeing, fairings, molar flares, lens housings ect. that green exterior layer is a semi-gummy protective layer to help resist scratches. We would polish the parts to a high shine on the exterior face, and paint the anti corrosion color on the inside (which always smelled like roasted peanuts to me for some reason) and then spray the polished side with this gummy green paint and then wrap in blue film and foam for shipping. At the 8 minute mark they are hosing the plane down to reveal the polished exterior side with what probably Acetone which is what we would use if we messed up the protective coating and had to spray again. Just wish the job paid more, was a good gig but doesn't matter much if it doesn't pay the bills.
The dark green you see on 737 fuselages on freight cars and prior to assembly is a temporary coating which is washed off before painting, not zinc chromate primer.
the translucent green shades on the fuselages of the aluminum Boeings is an anodize coating, it's not paint. It's cleaned with a solvent before painting. The pastel green coating is Hexavalent chrome, which is very toxic... the white interior paint is epoxy white, used to help prevent corrosion from the lavatories leaking and such.
As a college kid in the 1960s, I worked in a paint shop at Boeing's Renton plant, building 727s, 720s, and C-135 "looking glass" versions of the 707. Everything that came through our shop was painted zinc chromate green, but Boeing referred to it as SRF, meaning solvent resistant finish, no reference to corrosion resistance which it must have also been.
Heat does affect aircraft structures. When the B-29 was built in Georgia during WWII the plant had to be air-conditioned. The heat was bad for the workers and the aluminum expanded too much resulting in loose rivets when the aluminum was cold.
What you are seeing is the primer coating.
While the yellow/green/and sometimes brown color of these primer coatings come from the added chromate corrosion inhibitors (Barium Chromate and Strontium Chromate are modern choices), the primary function of this coating is not to be the main corrosion inhibition mechanism.
Aluminums are already treated with a chromate based chemical conversion coat BEFORE this green coating is applied. They've simply added chromates to the primer in order to help corrosion performance even further. The main purpose of the coating is to adhere to the metal with a strong bond because paints and pigments generally do not. It is also designed to be abrasive resistant, scratch resistant, flake resistant, impact resistant, and it is intended to provide a physical barrier (not just chemical) to keep electrolytes and oxygen away from the aluminum metal. In the case of fuel tank interiors, it needs to also be chemically stable against the harmful fuel additives as well. Then the topcoat goes on which protects the plane even further, though that's the layer that's primarily intended to be pigmented and provides less protection than the primer. The interiors are primed but not painted because the physical barrier against abrasion, scratching, moisture, and other mechanical damage from human interaction helps as well.
10:17 If I’m not mistaken, the reason the rudder is painting is so that it’s perfectly calibrated in the factory and can’t do so if it’s painted in the regular paint shop like everything else. The primary reason is not that it’s a composite
Paint on a plane weighs like a ton
@@AgentOffice Did you read my comment?
@@JayJayAviation yes I was agreeing, they need to balance that weight
@@AgentOffice I meant the calibration of the rudder deflection
Fiber parts have to be painted a light color or the sun will degrade the epoxy. This has nothing to do with calibration, that's why god invented trim tabs.
Air New Zealand paints the first aircraft of each model series black, I.E the first A320 to enter service was black, all other A320 are white.
Every Electron rocket starts out black and ends up white...due to ice. 🤪
"Which is equivalent to 6 Americans, I'm joking of course, 3 Americans" killed me
Pretty cool seeing WestJet being used as the painting example. They always have a few 737's parked near the vehicle exit at YEG terminal; and I know an instrument tech that works for them.
At times, the different colors of zinc chromate were used to indicate how many coats of primer had been applied. Yellow might have been first, followed by a coat of green, for example.
Could also indicate missed patches/uneven application as the yellow will show up a bit more readily.
The air newzealand planes look sick

Small world, I was suggested this video while waiting for the first coat of greenish yellow zinc chromate aluminum primer to dry on a batch of my Guitar amplifier chassis and panels.
So that dark green coating on the exterior of Boeing airplanes it's called a temporary protective coating "TPC" as you included, It is not a paint it's removable with solvent. Is to protect the thin clad aluminum on the exterior during manufacturing. Typically Yellow corrosion protection is used in fuel tank areas, green and on fuel tank areas.

@@brenatevi Ah I misclicked 8 instead of 3 thanks for the heads up
Thank you very much!!! The story of the zinc chromate green and yellow was very interesting even for an aircraft modeller like me. Your explanation solved many questions I had on the subject.
Would it be perhaps possible to make a video and explain why such a sharp difference between shiny aluminium and dull aluminium - magnesium panels on the B-36s and even on early B-52s? The magnesium was a lot used on the B-36 apparently, how is that possible? If I remember correctly magnesium is highly flammable!
Anyway, a big thank you for your nice videos!
Very informative, thanks. I never knew that beautiful shiny metallic green in fresh-from-the-factory aircraft was paint. I somehow thought the special alloys manufacturers would use nowadays perhaps had that colour naturally. My knowledge on aircraft cladding stops at WW2 Aluminium!
The Mach 2 Concorde was always white to keep it cool. It still stretched 6 to 10 inches in length due to this thermal expansion.
Because of friction at high speeds not the sun lmfao

Your humor as always gets me
Aircraft become really hot while on the ground. I know; I used to work on them. While it sits at the gate, the surface can get really hot under full sun. While in flight, it gets really cold. The hot-cold cycle of each flight fatigues the aircraft over time. Painting it white reduces the temperature range between on-the-ground and in-flight, resulting in longer life than if it had been painted dark. We even received a company-wide email with this rationale from Boeing advocating our airline (and others) switch to white. This was close to 20 yrs ago; just a few years after 9/11.
Ohhhhh, that last clause. Reeeeally wish you'd stopped at 'ago'. Now where did I leave my prunejuice?

I’m an a&p apprentice and work mostly on 40-50yo aircraft. A lot of them have the yellow primer but we clean and then spray the surfaces with green primer following a coat of dinotrol. It’s amazing how little corrosion these planes have
dinitrol? have some spray cans for the cars we have here :D
Simple. The green plumage is the hatchling colors. When they mature they’ll take on the adult coloration.
8:46 Aluminium Oxyde technically isn't corrosion-resistant. It is simply already oxydized (corroded) which means that it cannot be corroded any further
Al2O3 is corrosion resistant otherwise sodas and alcohols wouldn't last in them. There is a metal that will cause Al2O3 to act like rust does but I don't remember what it is.
@@LadyAnuB What I meant is that it's corrosion resistant mainly because there no more material able to be corroded on the surface.

@@orsaz924 This strict way of looking at it is spot on. It's already pre-corroded to a good depth. 😀

Great video and research. I had no idea what was the history of the Green Zinc Chromate coating.
It's off for it's first permenant paint job, that green surface finish washes off with solvent. I used to paint brand new aircraft with this temp sf on. The yellow was an epoxy primer which had to be re-done due to moisture absorbsion by the time it arrived anywhere.
Just recently subscribed to your channel and glad to see aviation being focus on this weeks videos!
The Boeing aircraft you are referring to are actually are coated with a lacquer to protect the outside metal from scratches during the manufacture and transportation. It's referred to as Spray Lac or Spray Lat, depending who you ask.This coating is removed just before the airplane is painted. Even after first test flights. This is why airplanes can be seen flying with this coating on.
super cool seeing that old school American livery on the 737. I've actually piloted that aircraft shown at 0:20!
I watched another video recently regarding the painting of aircraft. It said that tests by U.S. Army Air Corp during WWII concluded that painted aircraft required considerably less power to maintain cruising compared to unpainted, bare aluminum. The weight of the extra fuel required was a few times more than the weight of the paint. I'll have to search and try to find that link.
Saw the same video. The paint around the rivets help smooth the air flow which reduces drag which requires less power which saves fuel.

Yes, primer on an aircraft is there to prevent corrosion/oxidation but also a huge reason is also to act as an insulative layer between bare metal surfaces. This is especially critical in tank (fuel tanks of wings). In addition to this special in tank primer, most fasteners inside of the wings get cap sealed to insulate them further from the inevitable lighting strikes and St Elmo's fire that transport category aircraft are certified to endure. All of this falling under the category of EME (electromagnetic effects). EME and corrosion are specialized areas of aerospace engineering set up to establish the specifications and manufacturing processes designed to keep a plane flying safely over the course of it's useful 20+yr life before fatigue sets in. Composite and traditional metallic structures have drastically different standards to accomplish safe electrical bonding between surfaces and assemblies.
Your shorts are alright, but I really love your long form videos!
As someone who works for Boeing (spirit aerosystems) I see these big green “pickles” daily and deal with them constantly, the paint is still highly carcinogenic😅

It's fun to see scenes from around the Boeing 737 plant down the hill from my house. Yes, sometimes I have to wait at railroad crossings to watch green fuselages travel to the plant for final assembly.
There's benefit in cleaning/polish in fuel savings. I knew a 747 pilot who swore up and down about American waxing their 747s saving something stupid like 10% fuel and flying faster.

Circuit boards are green for the same reason! nobody likes staring at something super close-up for a long time, so the green helps.
That is not true at all. All you're doing is quoting a comment made in a Quora post made by some random user who knew nothing about it.
Circuit boards are usually green because they are covered in a solder mask made of epoxy resin and the original formula resulted in a green color. After a couple decades they eventually figured out how to make the solder mask in other colors but green is still the most common mainly because that's the default and cheapest color to use with printed circuit boards. PCB's can now be manufactured in almost any color you want, but those colors often cost more then the traditional green.
I was a structural maintenance guy in the Air Force and we used to get parts for our F-15s like that. We had to prime and paint them to go on the planes.
I guess that the "interior green" of WWII US planes was because of zinc chromate plus the need to avoid yellow for a more eye-relaxing green.
Also, Japan used a sort of turquoise similar to the Soviet planes interior.
11:00 cabin humidity? How do composites affect cabin humidity? Is it because now we can have higher humidity in the air without worrying about corrosion on the plane?
Yes exactly
Composites still suffer from fatigue. It just takes such a higher number of load cycles to failure that it's effectively a non-issue during the plane's entire life - theoretically.
One of your best videos!
6:00 If I had a nickel for each time classified military documents were leaked on War Thunder I'd have 6 nickels. Which isn;t a lot but it's weird it's happened 6 times.
alright I want to count them all, let's start with eurocopter tiger, not actually leaked but the guy who helped war thunder developers with the model got into some trouble, next the challenger 2 with a mechanic leaking the actual turret speed and some other stuff, leclerc with the famous autoloader and the type 99 with the sabot round specs being leaked. add all the remaining shit and correct me if I'm mistaken
If they add the SR-71, there’s a chance they might leak its actual top speed, which is still classified to this day.
I build scale model airplanes, and the interior of every plane from WWII is painted either zinc chromate yellow, zinc chromate green, or a combination of the two. RAF planes have their own interior green color, as do Russian planes. The colors simply called "RAF Interior Green" or "Russian Interior Blue/Green". The amount of money I've spent on bottles of these colors is insane. So glad to see a video explaining why this is done.
Great video, IMO.
I learned a lot.
Thank you.

Having worked in the aircraft industry for a few years, I believe you are talking about zinc chromate primer, you say yellow but it looked like it was more of a chartreuse ( slightly greenish yellow). I paused the video to add my comment, posted just before you said it.
Hexavalent chromium is highly carcinogenic. Interestingly, a different form of chromium, in tiny quantities, is an essential nutrient.
Even composites require either coating or pigmentation. Usually coating is preferred to pigmentation for high performance composites as pigmentation may interfere with the bonding of the resin to the fibers. The coating is needed to provide protection from surface corrosion due to ultraviolet light which will attack the resins used in the composites. The downside to this is it can make inspection more difficult.
The aloha airlines incident also had the two part glue that is used to atached the panels on the airframe had also become old and failed new and better glues are used today.

American airlines = built different
I was a painter at American airlines in the 90s. The people buffing the aircraft were having shoulder problems. I watched the trials of the robot buffer on a 727. It really sucked! But not hard enough to stick to the plane with suction cups.
I'm going to have a black cessna with racing stripes on it.
Black painted planes WILL get hotter when they are parked or aren't at 30 000 feet. If maintenance is taking place in a open area and not a hangar the workers will get melted from that heat.
"The most capable carrier-based bombers of World War 2... wore pink underneath!"
And they were made by ladies too, don't forget!
The word I got directly from American Airlines is that composite construction is the reason they discontinued the bare metal look. They changed the livery on both composite and metal planes for a consistent look across their brand.
Yep, I believe this was explicitly in their in-flight magazines a few years back as the reasoning in their letter from the CEO section, giving a farewell to the unpainted scheme.
I’ve seen the green fuselages on trains, going through Montana. I believe they are manufactured in Wichita Kansas, then shipped to Renton Washington.
You are correct sir, they are manufactured by Spirit Aerosystems of Wichita, KS and shipped across the country to the Boeing Renton,WA plant for final assembly. Now the bigger question is why doesn't Boeing build their own fuselages locally such as they do for the 777 manufactured in Everett, WA ?
I got mad when he made the joke about Americans' weight but he saved himself with that correction.
Hehe... premature failure...
