Why do people often choose white to paint airplanes rather than other colors?

Airplanes are a popular means of transport that people still use every day, but no one recognizes one common feature: these "iron birds" are often 'wearing' pale white shirts. Why is that?

1. Most aircraft have a small hole in the tail, but what effect do they have?
2. If you can open the plane in mid-air you will be a superman and this is why
3. Aircraft and 11 unexpected secrets that not everyone knows

In this world, there exists a reason for it to exist and the fact that the aircraft is often painted white is no exception.

Find answers to this problem through the sharing of R. John Hansman - professor of aviation and space science.

1. White absorbs heat less than other colors

Other colors often absorb more light, making it easier to turn into heat, making everything hot. Meanwhile, white is capable of reflecting all short waves, so light will not turn into thermal energy.

This is like the summer we wear a light colored shirt that will feel less hot than wearing a black shirt.

But maintaining a low air temperature is an important factor in fuel economy during flight.

2. Save on painting costs

To paint a plane, airlines have to pay a small amount at all, about 100,000-200,000 USD (about 2.2 - 4.4 billion VND). Besides, the more colors the higher the cost of painting.

In addition, to paint a plane is also time consuming, takes about 2-3 weeks. This affects the frequency of flights, and of course the consequences are hurting the airline's income.

3. White color is less faded

The aircraft is often in direct contact with the sun, ultraviolet radiation, and air, so it is easily discolored and easily old. But under the impact of the environment, the brighter the color, the easier it is to 'fall down'. And for airplanes to look like new, airlines have to spend a small amount of expenses.

White is less prone to discoloration under the impact of the environment, so it maintains the perfect appearance. Therefore, white will be the optimal choice of airlines.

4. White - easy to detect signs of incidents

White is said to be the best color to detect abnormal signs such as cracks in the shell, oil spills, or some other serious problem.

In addition, white is very prominent whether on land or underwater, helping the rescue team can find easier so if an accident occurs, even in the dark night.

5. It is valid when "change owner name"

Compared to a white painted plane, the colored paint will be "depreciated" more. Because when the plane is resold, the new owner will have to paint new while in white, they just need to repaint the name, the logo is fully usable.
