400 points super high score question What is the standard and scope of altitude division in meteorol

The altitude of the flight is not only determined by the type of aircraft, but also by visual flight, different courses have different altitude layers (0 to 179 180 to 359 are two sectors) to use the odd and even altitude, the specific altitude is arranged by the pilot to the air traffic control or to the air traffic control. For instrument flights and flights on routes, each route has a specified available altitude, and each flight also has its altitude, and any change that requires altitude is subject to permission, rather than different classes of aircraft flying different altitude layers, which is not divided as such.

There are many kinds of divisions in China, generally 0-3000 for low altitude, 3000-6000 for medium and high altitude, and above 6000 for high altitude.

1. There is no strict standard for "low-altitude flight" and "high-altitude flight", and the classification standards of the aviation community in various countries are often different, some classify less than 1000 meters as low-altitude, below 4000 meters as medium-altitude, and higher as high-altitude; Europe and the United States are often divided into 10,000 feet and 20,000 feet, each with its own differences. Countries will also further divide the airspace into more detailed altitude layers to allow separate planes in the air to stagger their altitudes from each other to avoid collisions.

The transition height is different for each district, depending on the situation.

Below the transition altitude, the corrected sea pressure correction altimeter is used, and the above correction is zeroed-359 according to the course staggered altitude to reduce the possibility of collision.

Flight: low-altitude airspace: below 4000 (currently opening soon) medium-altitude airspace: 4000-10000

High-altitude airspace: more than 10,000.

Upstairs, I talked about the division of flight, and I will continue to talk about the altitude division of meteorology.

The stratification of the atmosphere is thermodynamically stratified, with a total of five layers, from the earth's surface upwards to the troposphere (8 to 18 km, the air has obvious convection and turbulence movement in the vertical direction, hence the name), stratosphere (below 50 km), mesosphere (below 85 km), thermosphere (mesosphere to 500 km, because the atmosphere directly absorbs solar ultraviolet radiation, so the temperature rises to the top layer with the increase of altitude can reach 400 to 2000 degrees Celsius) and the fugitive layer (more than 500 km). Among them, the stratospheric atmospheric convection is very weak, the air is mainly horizontally moving, the content of water vapor and dust is very small, and the atmospheric transparency is high, which is an ideal aviation flight level.

The atmosphere in the middle layer has strong vertical movements, so it is not suitable for high-altitude flight. In addition, the lower troposphere (less than 2km) is also called the friction layer, and various natural conditions vary greatly, and it is not suitable for flying. Above the friction layer is also called the free atmosphere.

According to the ionization characteristics of the atmosphere, it can be divided into the neutral sphere (below 60 km, the air ionization is very weak), the ionosphere (under the action of high temperature and cosmic energetic particles, the air in the ionosphere is in a highly ionized state), and the magnetosphere (500 to 1000 km at the edge of the earth's magnetic field).

According to the change of gas composition with height, it can be divided into two layers of homogeneous and non-homogeneous layers, and its transition layer is from 85 to 100km. As for the classification, it can basically be as the name suggests.

Meteorology is basically stratified according to thermodynamics.

You can take a look at this.

I did it all myself, I hope it helps.

Article 22 The flight altitude level of the route is equipped as follows:

The true course angle is in the range of 0 degrees to 179 degrees, from 600 meters to 6000 meters, and every 600 meters is a height layer; Above 6,000 meters, every 2,000 meters is a height layer; The true course angle is in the range of 180 degrees to 359 degrees, from 900 meters to 5700 meters, and every 600 meters is an altitude layer; Above 7,000 meters, every 2,000 meters is a height.

degree layer; When equipped with a flight altitude layer, the altitude indicated when aligning the fixed indicator according to the compressor scale 1013 2 hPa (760 mm Hg) of the barometric altimeter; When measuring the true route angle, the starting point of the route is subject to the bend point.

If the individual segments of the route are tortuous, they shall be equipped in accordance with the specific regulations of the route.

Over-the-horizon flight defines the height of the cave god judgment, which refers to how many meters the height of the sea blind grip is lower than the whole country.

The barometric altimeter reflects the flight altitude by measuring the static pressure parameters of the atmosphere at the static pressure hole of the atmosphere.

Extended information] Barometric altimeter is an indirect measuring instrument that senses atmospheric pressure by using the barometric pressure sensitive element as a sensor, and then determines the altitude value according to the function between the barometric pressure and the altitude. The barometric altimeter can measure the relative altitude, absolute altitude, and standard barometric altitude of an aircraft.

The air pressure altimeter is composed of a mechanical transmission mechanism, a vacuum diaphragm box, a hydrostatic conduit and an indication component. Among them, the vacuum diaphragm box is the sensitive element of the barometric altimeter, which <>

The static tung pressure tube and the case are directly connected to obtain atmospheric static pressure; The indicator consists of a pointer and a dial to display the height value.

The flight altitude is indirectly measured by measuring the atmospheric pressure at the altitude at which the aircraft is located. Stove back.

Extended: Standard barometric altitude, which refers to the vertical distance of the aircraft in flight relative to the standard barometric surface. Many of the aircraft flying in the air may collide when the two aircraft are close to each other or rendezvous if they fly on different datums.

To this end, it is stipulated that the 101325pa air pressure surface is used as the benchmark when flying on the route and in transition, and the vertical spacing between aircraft is adjusted to implement air traffic control and ensure flight safety.

The altimeter in the aircraft is engraved according to the correspondence between the atmospheric pressure value and the altitude value in the standard atmospheric table. If the barometric scale of the barometric altimeter is adjusted to the quasi-atmospheric state of the barometric altimeter, the altitude indicated by the barometric altimeter at this time is called the standard barometric altitude.

The following description of the flying dust and the aerial scene is correct ()aWhen the height of Feipai Liang Mingxing is 500 meters, he can take pictures of the whole building and show the details of the building.

b.At an altitude of 5 meters, it is possible to photograph and display a panorama of an area.

c.When flying at an altitude of 100 meters, it is usually possible to present a large panorama (correct answer) There is no restriction on the flight altitude, and it is possible to fly up to 1000 meters to take a bird's-eye view.

Answer analysis: aAt an altitude of 500 meters, architectural details cannot be shown; b.When the flight altitude is 5 meters, the panoramic view of the area cannot be displayed; The djigoapp limits the flight altitude to 500 meters, and it is not possible to fly up to 1000 meters.

The altitude in the definition of flight within the line-of-sight generally refers to the relative altitude of people and aircraft not exceeding the take-off point () meters.
