White airplanes are the norm. (Save for the rebellious Southwest, but we digress.) This colour conformity isn’t without reason. Science and economics provide plenty of solid reasons why your airplane shouldn’t look like a kaleidoscope. Too bad.
It’s Gettin’ Hot in Herre
The main reason for snow white planes? Thermal science. MIT Aeronautics and Astronautics professor R. John Hansman told Business Insider that the color best reflects sunlight, which keeps the cabin of the craft cool (kind of like how long white clothing is your best bet in the desert). Shielding the plane’s plastic parts (usually the nose cone) and composite materials from the sun is especially important. White paint also lets potentially dangerous solar radiation bounce right off. Think of white paint like airplane sunblock.
According to a 2011 study published in Human-Wildlife Interactions, birds appreciate a bright white plane in the sky too. The study, conducted by researchers from Purdue University and the National Wildlife Research Center, found that white airplanes experienced fewer bird collisions than deep blue and light blues planes. This research suggests that our feathered friends can most easily pick white planes out of the sky, and swerve accordingly. Read more
