Why are planes mostly white?

Most aeroplanes you see are painted white. But this isn't just a style choice. There are some very solid scientific and safety reasons behind it. Let's dive into the complete details.

Saves Fuel and Improves Safety

White paint reflects sunlight, which keeps the plane cool. This reduces the load on the air conditioning and saves fuel. On the safety front, the white surface makes it easy for engineers to spot any cracks, rust, or oil leaks. Darker colours would hide these issues. Since planes are already very heavy, using white paint, which has less pigment, also helps reduce the overall weight, saving even more fuel.

Higher Resale Value for Airplanes

Airlines get a better price when they sell their white planes. Even a small weight reduction of one kilo can save a lot in fuel costs over time. White paint is also easily available and cheaper to maintain. Since it's a neutral colour, most companies prefer it, which means buyers don't have to spend extra on repainting.

A Nod to History

Using white paint saves airlines lakhs of rupees. It's also said that birds can easily spot a white plane against the sky, reducing the risk of bird strikes. There's a historical reason too. Early planes were made of aluminium, which is naturally silvery-white. Even when painting became popular, the white colour stuck, and the tradition continues today.
