Why do airplanes leave a white trail?

After leaving a cold winter month behind, we are getting ready to enter the sunny summer months. Now there will be less clouds in the air and we will begin to feel the warm rays of the sun on our bodies from a clear sky. In such periods, when you turn your head to the sky, you can see hundreds of different shades of blue at once. This magnificent image continues to decorate our background in our perspective, even if we are not aware of it. So when you look at the sky Have you ever noticed that a plane passes by and leaves a white trail behind it?

Some planes leave a white trail behind them as they continue on their way, which disappears over time. Probably everyone has seen this image many times over. So have you thought about what this permission is? Many people, like me, have reasoned about this issue. Most people think that this white mark leaves behind the plane. He thinks it is fuel residue, but in fact, the situation is not at all as expected.

Why do some planes leave a white trail behind?

The main reason airplanes leave a white trail behind them is heat. Although the altitude of each aircraft varies according to various factors, it is usually a aircraft between 30,000 and 40,000 feet; that is, it flies at an altitude of 9000 to 12.000 meters. Although it is sunny on the ground, the air gets colder as you go higher. Even the weather, where planes fly It can even drop down to -50 degrees at altitudes of 10,000 meters. The engines of airplanes compress this cold air and burn it together with the fuel. After the combustion process, the remaining air is thrown out with exhausts.

Normally, when hot air containing water vapor is thrown into an environment of -50 degrees, this water vapor is frozen at -50 degrees and due to low pressure. It instantly condenses and solidifies and turns into small pieces of ice. When we watch an airplane from below, we see that it leaves a white trail behind it. In fact, what we see is the water vapor that enters the aircraft’s engines and turns into ice crystal quickly. A The Boeing 747 aircraft sprays about 2.75 kg of water per second. The reason why the water here turns white is from the gaseous state to the solid state directly; that is, it turns into ice.

Do the white tracks left behind by airplanes harm the atmosphere?

What airplanes leave behind their engines white traces do not harm the atmosphere. This trace, which is essentially water vapor and only caused by the short-term change of the water’s form, disappears by itself after a short time.

Is the trace left behind by demonstration planes also produced by water vapor?

We explained the reason for the white trace left behind by airplanes. This permission, which is caused by the cold weather, has nothing to do with the colored tracks that low-flying aircraft such as a demonstration flight leave behind. Demonstrators use various steam engines to remove these traces.

Today we explained to you why the white mark on the back of the planes is caused. If you want more content like this, don’t forget to tell us in the comments section.
