    What about anodizing that giant part? Should retain most, if not all (I think), of its thermal conductivity compared to the same part with the normal oxide layer. This is assuming you really really want to color that part.

        For years AA did not paint their planes and left them a beautiful aluminum. If the plane "hull" (cylinder/body) is still made of aluminum, why aren't some planes left unpainted? (My guess: protection from corrosion? Then again, why not a "clear-coat?")

                  How much does the average paint job weigh on a 737 and a 747?

                    Excellent explained as always. I knew these things besides the trick with the heating from the engine to prevent icing. That proves how much thought and engineering goes into an aircraft.

                      Love how little paint chips into the engine problem has been mitigated. Just when you're feeling pretty good about yourself you can suck in several hundred pounds of Canadian geese simontaniously blowing out the engine and the pilots o ring staining his shorts.

                            So why did the Pepsi Concorde have to fly slower in dark blue than the white ones?

                              It varies in length because the outer hull starts to heat up because of friction with air.
                              White paint can radiate more energy away then dark paint and keeps the hull cooler. A cooler hull means less thermal expansion which reduces the stress to the hull structure.
                              Quite the opposite was done with the SR-71 ("Blackbird"). This plane was painted intentionally black. At ground it leaked like a sieve. But once in the air and at speed, the thermal expansion closed all the gaps.

                              @Mentour Pilot Doesn't it also have something to do with the fact that Concorde begins to vary in length by up to a whole 30cm when flying at supersonic speed?

                              Because of the heat issue. The white color would reflect away more heat than the blue did

                              Yeah, planes get hot due to all that air friction from flying at 600+ mph for so long. In fact Concorde used an especially bright white paint as it’s skin heated up to 300 degrees while flying at Mach 2

                                So, why dont airlines just partially paint the plane or not paint the plane at all (like American Airlines used to do)?

                                  Egor Levin Because the paint serves several important functions. The white actually reflects heat from the sun, unpainted metal would not do so as effectively. It also, believe it or not creates a smoother surface, which decreases air friction. This keeps the temperature of the metal cooler as air friction itself creates heat. It also helps the plane fly more efficiently, helping to keep down fuel costs. More friction equals more fuel used.
                                  It also protects the metal from oxidation and corrosion, much like your cars paint does.

                                        Mentor, is there any reason jet airliners from the 50s to the 80s had matt black noses?

                                          well the weather radar and other radars are in the nose, so that might have had something to do with it

                                              I suppose that if the nacelle were painted, there could be also chipped paint flowing through the compressors and cause an issue. Oh crap, I posted before the explanation which makes my post irrelevant.

                                                            I thought all the aluminium was coated by a treatment called anodising which forms a
                                                            coating on the surface . I may be wrong but it always was when I was in MOD contract manufacture.

                                                              Heat prolongs lifespan of metals so as Aluminum and Al-mag is concerned, hot metallic sufaces live longer, but not good for black painted surfaces for security reasons

                                                                Last week I flew to Austin, TX on Southwest and the aircraft was HOT. To the point where the flight attendants "STRONGLY encouraged" everyone to close their window shades and open the overhead vents to cool down the aircraft, so I can certainly see your point Mentour, thanks for sharing!
