We have been used to seeing airplanes in white for so long Most of us probably don’t doubt thishe is not even aware of this similarity.

But when we look at the sky, we often see something seeing white planes There are a few reasons.

Before the 1950s, airplanes were not painted, but polished.

Because they are the existing paints from that period It was quite expensive. In addition, the paint did not adhere to the metal body of the aircraft as well as it should.

However, over time, the adhesion performance of primers and paints increased and their durability was improved. While a bare aircraft needs to be polished about three times a year, paint is needed every few years, making polishing, About 0.06% to 0.3% more expensive would make it happen.

On the other hand, paint adds a significant amount of weight to the aircraft.

For this reason the paint is used both durable and lightweight It’s important to have. Because every kilogram of aircraft weight increases fuel consumption during takeoff and flight.

The reason why white is generally preferred for aircraft painting is the high albedo value of this color. So white, reflects most of the light that falls on it dark pigments absorb sunlight.

This is a dark colored paint, excessive heat and increased fuel consumption while the cabin is being cooled. caused by It means. This extra fuel obviously costs airlines much more.

It is also possible that a dark-colored paint is damaged more quickly by the sun.

Because dark pigments, By absorbing more UV radiation It breaks down the molecules in the paint. For example, painting surfaces in the lightest color, white, minimizes damage and heat caused by solar radiation.

The benefits of white paint are not limited to this. For example, military aircraft are often painted gray to blend in with the tarmac or hazy sky, while most other aircraft are as visible as possible on asphalt must be.

White paint also covers the exterior of the aircraft. Detection of cracks and other different types of damage makes it easier. In summary, the reasons why airplanes are generally white are; They reduce heat, reduce costs by saving money and increase safety.
