The German airspace is divided into several sectors based on geographical regions and altitudes. These sectors are controlled by different air traffic control centers, which are responsible for managing air traffic within their designated areas. The airspace is further divided into lower airspace (up to 24,500 feet) and upper airspace (above 24,500 feet), each with its own set of regulations and procedures. This division helps ensure safe and efficient air traffic management throughout the country. **

The airspace above your property is not owned by you in the same way that the land is. Airspace is considered a public resource and is regulated by the government. However, you do have certain rights to the airspace above your property, such as the right to exclude others from using it without your permission. Additionally, you may have some control over the airspace for certain purposes, such as building structures that extend into the airspace or using it for aerial photography. **

The kite enters the monitored airspace when its string reaches a length of 200 feet. At this point, it is considered to be within the controlled airspace and subject to the regulations and restrictions in place. It is important for kite flyers to be aware of the airspace boundaries and to adhere to any rules or guidelines set by the authorities. **

The division of the German airspace is carried out by the German air navigation service provider, DFS Deutsche Flugsicherung GmbH. The airspace is divided into different sectors, each managed by air traffic controllers who are responsible for ensuring the safe and efficient flow of air traffic within their designated area. The division takes into account factors such as air traffic density, geographical features, and military airspace restrictions. This division allows for the effective management of air traffic and ensures the safety of flights operating within German airspace. **

The days-long closure of the airspace was not an excessive measure considering the potential risks associated with volcanic ash. Volcanic ash can pose a serious threat to aircraft engines, causing them to fail. Additionally, the ash can severely limit visibility, making it unsafe for pilots to navigate through affected areas. Therefore, the closure was a necessary precaution to ensure the safety of air travel and prevent potential disasters. **

The regulation for airspace closure for civilian aircraft is typically determined by the relevant aviation authority or government agency responsible for managing the airspace. In general, airspace can be closed to civilian aircraft for various reasons, including national security, air traffic control requirements, special events, or natural disasters. Pilots and airlines are required to adhere to the airspace closure regulations and obtain necessary permissions or clearances before operating in restricted or closed airspace. Failure to comply with airspace closure regulations can result in serious consequences, including fines, license suspension, or legal action. **

To enter a higher airspace, one can contact the controller by using the appropriate radio frequency for the airspace they are trying to enter. Pilots can use their aircraft's radio to communicate with air traffic control and request permission to enter the higher airspace. It is important to follow the proper procedures and protocols for contacting the controller and obtaining clearance to enter the higher airspace. **

The low speeds in the upper airspace in Flight Simulator 2020 are caused by the simulation's attempt to accurately replicate the real-world conditions of high-altitude flight. At higher altitudes, the air density decreases, which in turn reduces the amount of lift generated by the aircraft's wings. This results in a decrease in airspeed, as the aircraft needs to maintain a higher angle of attack to generate enough lift to stay airborne. Additionally, the thin air at high altitudes also affects engine performance, leading to reduced thrust and further contributing to the lower speeds experienced in the upper airspace. **
