Why does an airplane have to fly at an altitude of 10,000 meters to maintain balance?

Since the birth of human beings, they have formed their own civilization, the rapid development of science and technology, human beings are also enjoying the convenience brought by science and technology, in the process of development, they have also encountered a lot of problems, human beings are special life forms with wisdom and consciousness, in the face of these problems, they can come up with ways to solve them one by one, which is the difference of human beings.

So far, science and technology have been developed enough, various means of transportation have emerged one after another, human travel has become more convenient, the emergence of these high-tech products, so that human life has become more abundant, and the efficiency has been greatly improved. Since entering the 20th century, seeing the emergence of a variety of high technology, human hearts are very surprised, and one of the greatest inventions in human history is the airplane, the airplane is very important to mankind, no matter where the plane, the plane can be successfully reached, it was invented by the Wright brothers. Why do planes have to fly 10,000 meters in the air?

Those who witnessed it tell the truth, so it is!

At that time, the Wright brothers flew the Flyer 1 for the first time, and it had the advantage of not landing on the ground, and it was able to fly on its own power. Humans have dreamed of flying into space for a long time. Since the advent of airplanes, these dreams have gradually come true, and at the same time laid the foundation in the field of aerospace, at that time, due to the limited technology of airplanes, the distance from the ground is still low, and the journey is relatively short, today's airplanes are completely different, not only flying at high altitudes, but also flying farther.

I don't know if you have noticed that the plane can fly stably at an altitude of 10,000 meters, why is this? Some professionals give a reasonable explanation, if the plane flies low, it may hit some birds, birds are also alive, and may also cause serious aircraft crashes and deaths, and then the gains outweigh the losses.

If you fly very low, you will also be affected by the wind, all of which is very dangerous, so often there is a stratosphere at an altitude of 10,000 meters, this stratosphere is extremely stable, and the aircraft becomes smoother in the process of flight, plus the stratosphere has less impurities, and there are more suspended solid particles, which plays a certain role in protecting the aircraft and is conducive to the pilot to better control the aircraft. It is impossible for birds to fly to such a high altitude, in order to fly more safely, some birds will be driven away at the airport before the flight, these birds cause certain safety hazards to the aircraft, although today's technology has been improved, it has not yet reached the peak stage.

The plane is not as stable as imagined, and there have been many crashes and deaths in history, and the possibility of survival is very small, so it is still necessary to consider carefully when taking a plane.

The upper-air atmosphere is divided into many levels, and the conditions of different levels are different, in the bottom atmosphere there is a troposphere with relatively unstable airflow, which is unsafe to fly in the troposphere, and in the stratosphere above 10,000m, the atmospheric movement is gentle, and the flight of aircraft is relatively safe.

Because there is no air convection at an altitude of 10,000 meters, the plane must fly at an altitude of 10,000 meters to maintain balance.

First of all, it has to do with the vertical stratification of the atmosphere. The atmosphere of 2000-3000 km thick can be roughly divided into troposphere, stratosphere and upper atmosphere from bottom to top.

The atmosphere is vertically stratified.

The tropospheric air moves significantly to the vibratosphere flow, which is not suitable for aircraft to fly for a long time (there will be strong turbulence) The troposphere thickness decreases from the equator to the poles, and the thickness is about 12 km in the middle latitudes. In order to avoid the strong convective movement of the air, the aircraft had to fly at an altitude of more than 10,000 meters, because this altitude was already the tropopause or stratosphere bottom, and the air convective movement was no longer obvious.

It has to do with the density of the atmosphere. The density of the atmosphere near the ground is high and the air resistance is high. As the altitude increases, the density of the atmosphere decreases rapidly, at an altitude of 2000-3000 km, close to a vacuum.

The aircraft flies at an altitude of more than 10,000 meters, with low atmospheric density and low drag, which can save fuel.

It has to do with atmospheric visibility. Clouds, rain, smoke and dust in the atmosphere are mainly distributed in the troposphere. These can affect the visibility of the atmosphere. At an altitude of more than 10,000 meters, there are almost no clouds, rain, haze, sand and dust, and the atmospheric visibility is excellent.

It has to do with geospatial security. There are more birds flying at low altitudes, which will seriously affect the flight safety of the aircraft. Moreover, our production and life are basically carried out in the bottom troposphere, such as military exercises, balloon flying, kite flying, etc., which may also bring hidden dangers to aircraft flight.

Associated with noise pollution. Aircraft are noisy in flight, and flying at high altitudes can minimize noise pollution.
