ABSTRACT
The Aeronautical Navigational Service Provider (ANSP) is responsible for the provision of services, but at airports, in many cases, the execution of this responsibility is delegated to a specialized branch. The level of services that need to be provided at an airport is defined by international civil aviation organization airport categorization. As such, airports are categorized for required air-side space, the safety at the airport and the dimensions of runways. The airspace around an airport and designated to traffic to and from that airport is called the airport’s control zone. The Airport’s Ground Control governs all surface traffic at the airside of an airport, aircraft as well as vehicles. It is very visible to the public as every airport has a high rising control tower where Ground Control is located. The ANSP is also responsible for providing navigational devices around the airport and for providing instrument devices enabling pilots to land at the airport.
