Why Are Planes Usually White? – Webtekno

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

But when we look at the sky we often see seeing white planes There are some reasons.

In fact, before the 1950s, airplanes were not painted, but were polished instead.

Because the existing paints of that period It was quite expensive. Additionally, the paints were not adhering to the metal body of the aircraft as much as they should.

However, over time, the adhesion performance of primers and paints increased and their durability improved. While a bare aircraft needs to be polished about 3 times a year, paint is needed every few years, making polishing, Around 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 to be used both durable and lightweight It is important to have. Because each kilo of the weight of the aircraft increases the fuel burned during takeoff and flight.

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

This is a dark colored paint, excessive heat and increased fuel consumption while cooling the cabin. caused by It means. Naturally, this extra fuel costs much more for airlines.

It is also possible that a dark colored paint will be damaged faster by the sun.

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

The advantages of white paint are not limited to these. For example, military aircraft are often painted gray to blend in with the tarmac or hazy skies, 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 damages makes it easier. In summary, the reasons why airplanes are generally white are; They reduce heat, reduce costs by saving money, and increase safety.
