What is the general flight altitude of an airplane? Why is it safest to fly in the stratosphere?

Aircraft generally fly at an altitude of about 7,000 to 12,000 meters, and it is safest for aircraft to fly in the stratosphere for three main reasons. First of all, flying in the stratosphere, the aircraft is more stable and safer. Secondly, the visibility of the stratosphere is relatively high.

In addition, birds are generally not encountered, and the safety factor is higher.

The flight altitude of the aircraft is determined according to the size of the aircraft, their altitude is different, most of the flight altitude of civil aircraft above medium size is about 7000 to 12000 meters above sea level, for example, the maximum flight altitude of the Boeing 737 family is 12500 meters, the maximum flight altitude of the Airbus 320 series is 12000 meters, and the maximum flight altitude of the Airbus 330 is 12500 meters. Overall, they are flying in the stratosphere. The reason why flying in this stratosphere is because it is the safest.

First of all, flying in the stratosphere, the aircraft is more stable and safer. The air temperature in the stratosphere is warm at the top and cold at the bottom, the cold air floats on top and the cold air sinks below, and the atmosphere does not produce convection and is relatively stable. When the plane is flying, it will not cause turbulence due to the upward and downward convective movement, and it can move forward with the help of the horizontal flow of the wind, which is more fuel-efficient.

If it is in the troposphere, there are clouds and fog in this place, and there is more convective movement, which is easy to turbulent, and it is easy to cause plane crashes.

Secondly, the visibility of the stratosphere is relatively high. Because stratospheric water vapor and suspended solid particles and impurities will be relatively less, and the weather is relatively clear, the light is good, the visibility will be a little higher, and you can see more clearly when flying at high altitude. It's because you can see it clearly, so it's relatively safer.

In addition, birds are generally not encountered, and the safety factor is higher. When the plane is flying in the sky, it is necessary to consider whether it will encounter birds in the sky. In order to avoid this situation, they will choose to fly in the stratosphere, because the altitude of the bird is generally not up to the stratosphere.

If you encounter these animals, it is likely to affect the flight of the aircraft, and even cause a plane crash.

That's all for the altitude at which the aircraft flies and why it chose to fly in the stratosphere.

Generally, the flight altitude of passenger aircraft is between 6000 meters and 12600 meters, and the aircraft is the safest to fly in the stratosphere, because because the air temperature in the stratosphere is warm in the upper part and cold in the lower part, the warm air is warm and light, floating on the top, and the cold air is cold and heavy, sinking below. The atmosphere is relatively stable. There is basically no upward and downward convective movement of air.

Aircraft generally fly at an altitude of around 7,000 to 12,000 meters above sea level. The stratosphere is a layer of hot and cold in the earth's atmosphere, where there is basically no up and down convection movement of air, the atmosphere is relatively stable, there is basically no up and down convection movement of air, the plane will not be turbulent, and it can save fuel with the help of the horizontal flow of wind.

The above are the safest reasons for aircraft to fly in the stratosphere, I hope it will help you.

The flight altitude of the aircraft.

Generally around 7,000 to 12,000 meters above sea level; Because the plane is in the stratosphere.

There are no birds or other flying creatures on it, and the temperature in the troposphere is relatively stable, which is more suitable for aircraft flying and can also ensure the personal safety of customers.

The flight altitude of the aircraft is generally 8,000 meters, because the stratosphere encounters fewer obstacles, the air pressure is not particularly large, and the whole flight is relatively smooth.

The planes are all in the stratosphere.

There are several reasons for flying, first of all, the air flow here is more stable, and it is safer for aircraft to navigate. Secondly, the air pressure here is also within the tolerance range of the plane, if it is too high, even the person who flies will have problems, and finally it can avoid certain dangers, such as thunderstorms and birds.

The process of aircraft flight is generally relatively smooth, that is, because the plane flies in the stratosphere, the altitude is about 7000 12000 meters, the specific altitude should be changed according to different latitudes, where the airflow is relatively stable, there will be no turbulence, which is relative to the troposphere.

In other words, because the troposphere is mostly cold and hot air meet, the air flow is very chaotic, and if the aircraft encounters this air flow when flying, the probability of danger will be greater.

For every 1,000 meters of altitude ascent, the temperature drops by degrees Celsius.

Therefore, the stratosphere of the aircraft also has a limit, and it also involves problems such as air pressure and aircraft loss, but if it flies too low, it is easy to encounter thunderstorms, fog and other weather, so when the aircraft flies, the altitude will be changed according to the specific situation, and the process will be gradual, otherwise it will suddenly fall sharply, which will cause harm to the body of the passengers. Of course, when changing the altitude, we will also communicate with aircraft that are on the same route or have intersections to avoid collisions.

Because because the planes fly high enough, the oxygen is thin here, and there are generally very few birds flying, and in addition to this, there are some *** and hot air balloons.

It also flies at low altitudes, so flying in the stratosphere avoids encountering these uncontrollable factors. But there are no absolutes, and there are some clouds that are too thick, accompanied by thunderstorms.

In this case, the plane has to fly as close to the clouds as possible, because it is often accompanied by strong air currents, which have an impact even greater than the troposphere.

Because the height of the stratosphere is suitable, there is no risk of hitting the mountain, the noise is relatively small, and the stratosphere is stable and not easy to be impacted.

Because the stratosphere is the most stable. Best for your normal flight, so the plane is generally flying in the stratosphere.

Because the stratospheric airflow is relatively stable, aircraft are the safest because they experience the least fluctuations in this atmosphere.

Airplanes generally fly in the upper stratosphere and troposphere.

Theoretically, the plane flies most smoothly in the stratosphere, but because there are many planes in the sky, the plane needs to fly according to the specified altitude and route to avoid collision, so the specific flight altitude needs to be according to the instructions of local control. Civil airliners are supposed to fly in the upper troposphere, but military aircraft can often fly in the stratosphere.

Civil aircraft generally fly at an altitude of 7,000-12,000 meters after takeoff, and some fighters can fly at an altitude of 30,000 meters. It can be seen from this that in fact, for civil aircraft, most of the time is at the top of the troposphere or at the junction with the stratosphere, and part of the time at the bottom of the stratosphere. Fighters can fly in the lower stratosphere (i.e., the stratosphere), generally at altitudes of no more than 30,000 meters.

Main features of the troposphere

1. The temperature decreases with the increase of altitude. This is mainly because the vast majority of the heat in the tropospheric atmosphere comes directly from the ground, so the higher the atmosphere above the ground, the less heat it receives and the lower the temperature. On average, every 100 meters of ascent, the temperature drops by degrees Celsius.

2. The air convection movement is significant. The upper part of the troposphere is cold and the lower part is hot, which is conducive to the convective movement of air. The low latitudes are heated more, the convection is vigorous, and the troposphere reaches a high height. The high latitude area is less heated, and the lower the trospheric height of the grinding key silver.

3. Weather phenomena are complex and changeable. The water vapor and impurities near the ground are transported upward by convection, and with the decrease of air temperature during the lifting process, it is easy to form clouds and cause rain. Weather phenomena such as clouds, rain, and snow all occur in this layer.

Stratosphere. Airplanes generally fly in the upper stratosphere and troposphere. Theoretically, airplanes fly most smoothly in the stratosphere.

However, because there are many planes in the sky, the planes need to fly according to the specified altitude and route to avoid collisions, so the specific flight altitude needs to be according to the instructions of local control.

The stratosphere, also known as the stratosphere, is a layer of the earth's atmosphere that is hot at the top and cold at the bottom, which is divided into different temperature layers, where the high temperature layer is at the top and the low temperature layer is at the bottom.

The troposphere refers to the layer of atmosphere closest to the earth's surface, and it is also the lowest layer of the atmosphere, which is the most dense, containing almost 75% of the mass of the entire atmosphere, as well as almost all water vapor and aerosols.

In the stratosphere, large passenger aircraft mostly fly in the stratosphere to increase flight stability. The reasons are: High visibility: The stratospheric water vapor, suspended solid particles, impurities, etc. in the earth's atmosphere are very small, the weather is relatively clear, the light is relatively good, and the visibility is very high, which is convenient for high-altitude flight.

The stratosphere is stable under force, the atmosphere of the stratosphere is warm and cool, the atmosphere is not convection, and the stratosphere is mainly in the stratosphere.

Mainly in the troposphere, there are not many times to fly in the stratosphere, mainly long-distance flights such as intercontinental flights will reach that height. The country is mainly troposphere.

The maximum flight altitude of different aircraft short-route aircraft generally flies from 6000 meters to 9600 meters, and the aircraft of long routes generally flies from 8000 meters to 12600 meters, and the maximum flight altitude of ordinary civil airliners will not exceed 12600 meters, so that the flight altitude of some business jets can reach 15000 meters.

Aircraft in the cruising state consume the least amount of fuel per unit distance; At the same time, the maximum range of the aircraft is calculated according to the cruising speed, and even the transfer range of the fighter is calculated according to the cruising speed of the aircraft.

So cruising is the most fuel-efficient segment of an aircraft's flight, which occurs between climb and descent, that is, when the aircraft is close to the concession and enters the descent position to prepare for landing, which usually takes up most of the flight time.

5. Boeing 777:2 engine, 380 seats, cruising altitude 11000, maximum range 9000, 10 seats per row, maximum flight speed 830.

Dear, thank you for your patience, I have helped you find the result; The reason why the aircraft is suitable for flying in the stratosphere is 1, high visibility. There are very few stratospheric water vapor, suspended solid particles, and impurities in the earth's atmosphere, and the weather is relatively sunny and clear, the light is relatively good, and the visibility is very high. 2.

The force is stable. The atmosphere of the stratosphere is warm and cool, the atmosphere is convection, and the advection movement is the mainstay, and the force of the aircraft in it is relatively stable, which is convenient for the pilot to control the frame. 3. Low noise pollution.

The stratosphere is high above the ground (about 12 km to 50 km), and aircraft spend most of their time flying in their trousers, so the noise pollution to the ground is relatively small.
