 Merriam-Webster defines the term **airspace** as "the space lying above the earth or above a certain area of land or water".
-According to the [Chicago Convention on International Civil Aviation](https://www.icao.int/publications/Documents/7300_cons.pdf) of 1944, every state "has complete and exclusive sovereignty over the airspace above its territory". Horizontally, a state's airspace extends over its entire territoriy, which also include territorial waters. According to the [United Nations Convention on the Law of the Sea](https://www.un.org/Depts/los/convention_agreements/texts/unclos/unclos_e.pdf), territorial waters extend up to 12 nautical miles (22.2 km) from a state's coastline. Vertically, a state's airspace begins at the earth's surface and ends at an altitude of 100 km above mean sea level, which is also known as the [Kármán-Line](https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line).

 The Kármán-Line - as a legal differentiation - separates the Earth's atmosphere from space.

-## Aeronautical Information Management
+## \acr{AIM}
 Aeronautical Information Management (AIM) is considered with the collection, assembly, publication, exchange, and dissemination of quality-assured, timely and digital aeronautical data in collaboration with all relevant stakeholders. Aeronautical data includes aeronautical information publications (AIP), notice to airmen (NOTAM), preflight information bulletins (PIB), and aeronautical information circulars (AIC).
 
 **Aeronautical Information Publications (AIP)**, which contain "aeronautical information of a lasting character essential to air navigation", see [ICAO Annex 15][Annex_15], are issued by a state or by an authority of the state, such as an ANSP. Since their structure is standardized by ICAO Annex 15, AIP usually consist of three distinctive parts:

 Closer to aerodromes radars with a higher revolution are dployed. This increases the accuracy of measurement within the arrival and departure airspace. This allows for a reduction of the separation minima. Within Europe and the United States, the required minimum is 3NM unless wake-turbublence categorisation requires a wider separation distance.   
-Within the close proximity of airports and given the deployment of so-called precision radars, the separation minima can be further reduced to 2 1/2 or 2 NM.

-## Communication, Navigation, Surveillance (CNS)
-To ensure safe and efficient air transportation, Air Traffic Management (ATM) relies on infrastructure, services, and functions in the areas of Communication, Navigation, and Surveillance (CNS). As such, communication enables the exchange of information, be it in spoken or written form, between crews of aircraft and/or air traffic control. Navigation encompasses all services and infrastructures by means of which aircraft crews find their way through space in order to get from one place to another quickly, efficiently, and safely. Finally, surveillance comprises all technical possibilities by means of which air traffic control can determine the position of aircraft. In the following, the most important services, technologies, and processes in the field of CNS are presented.
