Why Are The Airplanes Usually Painted White?

Sat May 21, 2005 6:38 pm

Hi everybody...


Is there any reason that the planes are usually painted white? (except some Qantas 747s)

Is it because cheap or any other reason?


Thnx for the replies

White reflects heat also keeps operating costs down, I think is the jist of it.

White oozes crisp minimalism and is very handy if the airline needs to sell the aircraft in a hurry - the new owner doesn't have to repaint the whole aircraft, just the logo and company name - very economical.

Yes, quite right Catatonic...white reduces ambient temp. inside the cabin. This was discovered I believe in the 1950's, and AA painted a DC-6 or DC-7 in an experimental white livery, but AA's President, C.R. Smith, hated the look, so he ordered it stripped and the idea abandoned.

Note that reducing the cabin temp. isn't just a passenger comfort issue...it reduces the amount of air conditioning needed, thus saves aircraft fuel or gas for a ground power unit on layovers.

I believe other colors have the effect, too, but I think it was found that white was the best.

I read somewhere that AA saves over $500,000/year in operating costs by not painting their aircraft.

Beside the quite technical issues like heat reflection, I think it also has to do with the logical "design view" of the creative minds behind:

Canvas is WHITE, sheets of paper are WHITE .. white is where every design begins, it's THE basic, neutral color ... so I think it has this very down to earth explanation.

I like the story, but I am not certain it is accurate. Sorry.

I think BOAC was painting the top half of their aircraft white in the late 40's partly because of the tropical work.

I think that when they introduced the Stratocruiser in 1949, that aircraft had the white top, even though those planes weren't going tropical. All my early memories of the Constellations in 1951/52 to/from Singapore/Australia were also white top.

In 1952, all the BOAC tropical subsidiaries (Aden Airways, Arab Airways, etc) were white top, so it must have been around for a while.

I suspect that Pan Am Stratocruisers had the white top, too.

But my memory may be imperfect.  Smile

when thinking about larger aircraft such as the 747 and A380, painting most of the fuselage will add almost 500kg to a ton to the aircraft weight, although this doesnt sound like a lot, long term calculations will show that some sort of money is saved from avoiding this
The only time there is too much fuel onboard, is when you're on fire!

Sounds like an aviation myth. First of all, a little over $1000/plane/year is peanuts and most likely within the margin of error. Secondly, AA planes are, in fact, painted.


Useless trivia: Concorde liveries were restrictive and had to be mostly white, as shown here with all the actual and proposed liveries: http://www.concordesst.com/history/orders.html

Only the parts of the a/c that are painted are made of composites or nonmetallic materials. So that means the tail, the engine nacelles, and the nose cone. Other than the American Eagle a/c, the only non-transitional/hybrid livery AA a/c to ever be painted were some of their A300s, which were delivered painted grey due to the metals used on the A300s (same reason why Eastern's never wore the standard EAL bare metal scheme). Eventually coatings were developed so that AA could have their A300s in the standard livery.

The January edition of Airways magazine had an interesting article on 'Paint Or Polish' It had special mention of AA and their silver ( unpainted) birds which it stated
" American Airlines saves more than $2 MILLION a year in fuel costs thanks to these weight savings " some of AA planes such as the Airbuses are painted because of the different types of aluminum or composites used. The article also stated that in the January 04 edition of American Way the president and CEO of American had a page long piece on how the polished birds save AA money. Sometimes hundreds of lbs of paint is required to paint an aircraft which adds weight. White paint needs more layers than darker colors but helps keeping the A/C cooler

You know, upon reflection, it might have been earlier, maybe the 40's, that AA tried the white paint, on a DC-3, and then again in the 50's on a DC-6...they may have tried to convice C.R. Smith more than once; the story is in Robert Serling's excellent history of AA titled "Eagle".

I was not aware of BOAC doing it that early, thanks for the info!! I'd also forgotten about the PAA Strats.

Clearly, it's MY memory that is faulty!

It's not something you want to think about but if the aircraft comes down in an accident, whether on the ground or on water, it easier to spot being white.
I wish that all skies were orange and blue!!

I'm surprised that one reason being suggested is to do with cooling - certainly white is a reflective 'colour' and would help keep the aircraft cooler than a black aircraft while on the ground, but at 30,000ft the air temperatures fall below freezing - I would have thought that an aircraft at cruising altitude wouldn't need to be kept cool. I'm not a physicist so would be interested to know whether this is in fact the case, or whether the friction of the air passing the aircraft surfaces generates lots of heat. This isn't the space shuttle after all!

I'm sure it's just because everyone else does it and, as someone has suggested, to enable aircraft to move from one carrier to another with ease. In the past twenty years we seem to be moving towards aircraft designs that are more colourful and serve an advertising purpose: Wanula dreaming, the LOTR Air NZ design, Peter Max etc...

Interestingly, other than the Pepsi concorde, have any airlines used their aircraft for commercial advertising? I would imagine the revenue that could be generated would easily compensate for the extra running cost caused by weight etc...?

Most aircraft are painted in white for branding/marketing purposes and nothing else. Period.

For a designer, white is actually no colour but rather the result of brightening whatever colour to the maximum. Hence, you can use white without messing around with the so called colour angle and coulour contrast set by the brand's original colours. Same goes for grey and black.
White stands for purity, clearity, seriousity and, as far as communication between the company and its clients is concerned, for simplicity and confidence.

Same goes for cruise ships, btw.

The fact that white helps to keep the plane cool while on ground is a secondary reason at best.

Low cost carriers do so frequently. All other carriers shouldn't do it, because it would shift the brand's image towards those of no-frills airlines.
