Isn’t white paint also thinner, or is the colour irrelevant, it’s just that Boeing won’t bother with other colours and warns against adding a second layer?

Paint on planes has a spec'd thickness regardless of color. Too thick fucks the panel during a lightning strike, too thin and you get incomplete coverage/corrosion issues. Given the method of applying paint (by Joe-Bob and his paint gun) its a surprisingly controlled tolerance.

The number of supremely tarted-up 737s hanging around the north ramp of KBFI at any given moment would indicate to me this is not the case.

I think he was probably referring to GE's insistence that the GENx chevrons could only be painted white or blue because of composite delamination.

It was actually to promote better laminar flow over the nacelle; apparently thicker paint would mess with it. GE/Boeing also backed off that demand not long after they made it.

I don't understand why Boeing can't just publish the relevant Rz spec and wash their hands of the issue

Boeing should make a special edition 787 that's not painted at all -- just a clearcoat over the composite.

As Sagebrush points out they definitely don't arrive with finished paint, it'd never make it through the line without damage. Also, I would expect they need to install fasteners that they also electrically bond through as I doubt they add wire ground straps to skin panels.

Finger Prince posted:They're fully painted default white before they ever see daylight. The parts arrive at the factory pre painted. No, they're not. However, the carbon is not on the outer surface of carbon aircraft skins. There's a layer of copper mesh or foil for lightning strike protection, and a layer of fiberglass for corrosion protection and a suitable painting surface that makes up the final outer layer. The inside surface is also mostly covered in fiberglass in order to avoid having to use fay sealing for metal brackets. There's plenty of pictures on the internet of unpainted A350's and 787's being towed between hangars (usually on their way to the paint hangar), and they're all that same weird brown you get from the reddish-brown of the copper being just slightly visible through the off-white fiberglass ply. There ARE carbon parts that don't have copper or glass plies, but they're all in locations that are never exposed to sunlight once installed, and most remain unpainted. The frames and the clips holding them to the skin, for example, which are completely covered by the outside skin and the interior paneling. Source: I literally wrote the plans for manufacturing skins for one of them, AND I handled the deliveries to the OEM, notably unpainted when we shipped it.

Counterpoint, I've seen them being put together, and clambered around inside and outside them at various states of being put together, and have been to the production line on multiple occasions. But don't just take my word for it; http://bfy.tw/A0Uo Also before they went down the line like that, they towed them across to the paint hangar at night to paint them white, so technically they were painted white before ever seeing daylight. In one of those images there's even an Air Canada fin with a white fuselage. They all have a white basecoat before going across the road for final customer paint.

Comrade Gorbash posted:There's also an economic factor. Every time a big fleet operator picks a color scheme that's predominantly white, it makes it more likely others will follow. It becomes the color most likely to be in stock already, and the color with the biggest production capacity. You can get whatever color you want in several months for more... or you can get white plus a trim color right now, for less. Of course, for most paints white is the base color anyways, so its inherently cheaper even without economics of scale. This makes sense. Also I vaguely remember a Star Wars Expanded Universe book where some dude ends up with a Star Destroyer and wanted to paint it red and it cost quite the sum of money to even find enough of the paint.

The union supports discussion of a non profit private corporation like Canada's. I don't think that anyone is confused about how it COULD go down, but the union wants to stay involved in any changes instead of impotently opposing something the government can unilaterally impose anyway. NATCA President Paul Rinaldi's article in ATCA Journal (p. 21) http://www.natca.org/images/Newsroom/FAAReauth/ATCAJournalQ22015.pdf Another, newer piece from Paul: http://www.natca.org/images/NATCA_PDFs/Current_Legislative_Issues/ATMmag2016reform.pdf See https://www.natca.org for more information on our union, and the horrible outlook of staffing and funding of the U.S. ATC system.

ApathyGifted posted:No, they're not. Can confirm this for the 787 frames, whether or not the clips are painted seems up to the vagaries of the engineer designing the assembly though judging by the number of part rolls I get that have no changes to engineering except adding or removing paint from them
