Air traffic control ( ATC) is a service provided by ground-based air traffic controllers (people) who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organise and expedite the ...

These are usually set 28 days in advance. In many countries, the structure of controllers' shift patterns is regulated to allow for adequate time off.
List of area control centers. Area control centers (ACCs) control IFR air traffic in their flight information region (FIR). The current list of FIRs and ACCs is maintained by the International Civil Aviation Organization (ICAO). [1] Note that the cited ICAO source gives the shapefile coordinates for each FIR, and also its page source gives a ...
Large regional differences are detected: the Asia-Pacific has the shortest estimated average recovery time of 2.2 years, followed by North America in 2.5 years, and Europe 2.7 years. For air freight demand, a shorter average world recovery time of 2.2 years is predicted if compared to passenger demand. On the regional level, Europe and North ...
Remote and virtual tower (RVT) is a modern concept where the air traffic service (ATS) at an airport is performed somewhere other than in the local control tower. Although it was initially developed for airports with low traffic levels, in 2021 it was implemented at a major international airport, London City Airport (84,260 aircraft movements ...
A traffic alert and collision avoidance system ( TCAS, pronounced / tiːkæs /; TEE-kas) is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air ...
