Kármán line. The boundary between the atmosphere and space as defined by the International Aeronautical Federation, with an altitude of 100 km, is the Kármán line. Outside the Kármán line is space, and in fact there is no clear boundary between space and the Earth's atmosphere, because the atmosphere gradually thins with altitude.
Assuming a constant atmospheric temperature, the atmospheric pressure will decrease exponentially from 1000 millibars at sea level to zero as the altitude increases. Therefore, the International Aeronautical Federation defines an altitude of 100 kilometers as the Kármán line, which is the current boundary between the atmosphere and space.

The Kármán Line is also used to distinguish the upper limit of airspace, and although there is no upper limit in standard airspace, it is agreed that the host country has no right to intercept non-offensive man-made equipment beyond this height.

Kármán line. It refers to the Earth's atmosphere and spaceThe dividing line
The Kármán line is a virtual concept located at an altitude of 100 kilometers above sea level, often used as the dividing line between outer space and the Earth's atmosphere. This definition is accepted by the International Aviation Federation, the standard-setting and record-keeping body for international aerospace.
But according to a freshly baked **, maybe its value is a bit too regular. New research suggests that outer space boundaries should be set at an altitude of about 80 kilometers from Earth.

jonathan c.McDowell's view, he argues that the yardstick of space boundaries to less imitation should be based on the orbital and suborbital trajectories of satellites.
Interpretation of the definition:
This line represents the mean or median value of a measurement. It is measured in a similar way to some other legal boundaries such as mean sea level, meandering lines, and tidal lines, but is far more complex than them. When it comes to the legal Kármán demarcation line, there are many other considerations to consider besides aerodynamic lift.
factors. There are many people and the literature that discuss these factors. These factors include the physical state of the air; the possibility of biological and human survival; Frankly logically join the airspace because of the non-existence of an air start.

The Kármán Line is a line located at an altitude of 100 km (330,000 feet) above sea level and is mostly recognized as the dividing line between outer space and the Earth's atmosphere. This line is accepted by the International Aviation Association (an international aerospace standard-setting and record-keeping organization) and is the definition of the current boundary between the atmosphere and space.

The Kármán line is the dividing line between space and the atmosphere. The Kármán Line is located at an altitude of 100 km above sea level and is considered by most people to be the boundary between outer space and Earth's atmosphere. The Kármán line takes its name from Theodore von Kármán, a Hungarian-American engineer and physicist who worked primarily on aeronautics and astronautics.
For the first time, Carmen calculated that at this altitude, the atmosphere was too thin to generate enough lift to support the vertical burial of aviation. The line is therefore accepted by the Fédération de l'Autérica, as the current boundary between the atmosphere and space.
Kármán Line Definition:
The higher the altitude, the thinner the atmosphere. However, the atmosphere does not suddenly disappear at a certain altitude. Because there are many interpretations of what layers the atmosphere consists of, there are also many definitions of the boundary between the atmosphere and outer space.
The Kármán line is a relatively abrupt demarcation line defined by the consideration of medium fiber considerations: the aircraft is able to stay in the air because the aircraft has a certain relative velocity with the air around it (true airspeed), so that the wings can generate the lift force that supports the aircraft. The thinner the air, the greater the airspeed required to generate sufficient lift.
