Video answers: Why are aircraft always painted white?

Here are the answers to last Friday’s video, enjoy!

Suggested ICAO level for video: 5+

  1. They’re usually a green colour, which is from an anti-corrosive paint which is used.
  2. Approximately 1,100 kilos of paint is applied to an A380 in the paint shop.
  3. They’re inefficient because a detailed paint job adds unnecessary extra weight to a plane that causes it to burn more fuel as it flies.
  4. It cost them money because they had to frequently polish the surface to prevent it from degrading and becoming tarnished.
  5. It can easily reveal oil leaks, dents and cracks which may occur and be more difficult to spot with other colours painted on the fuselage.
  6. There is a rumour that a white paint job is less prone to bird strikes due to the higher contrast.
  7. It helps to keep temperatures down as white paint is twelve times more reflective than darker colours. This also helps reduce the thermal expansion of the plane and the associated stress placed on it.
  8. Concorde needed a unique type of paint that could deal with the enormous heat generated in the wings during flight.
