Air traffic controllerAn air traffic controller (ATC) is a person responsible for the coordination of air traffic within controlled airspace. Typically they work in area control centers or control towers, where they monitor aircraft movements and maintain direct communication with the pilots. The profession dates back to the early 20th century, evolving alongside advances in aviation and radar technology to meet the growing demands of air travel.
EurocontrolThe European Organisation for the Safety of Air Navigation, commonly known as Eurocontrol (stylised EUROCONTROL), is an international organisation working to achieve safe and seamless air traffic management across Europe. Founded in 1963, Eurocontrol currently has 42 member states with headquarters in Brussels, Belgium.
Pilot in commandThe pilot in command (PIC) of an aircraft is the person aboard an aircraft who is ultimately responsible for its operation and safety during flight. This would be the captain in a typical two- or three-pilotaircrew, or "pilot" if there is only one certificated and qualified pilot at the controls of an aircraft.
AirspaceAirspace is a portion of the atmosphere controlled by a country above its territory and territorial waters, which is under the country's sovereignty and regulatory control. Internationally, allocation and management of airspace is coordinated by the International Civil Aviation Organization (ICAO), which was established through the 1944 Chicago Convention and came into being in 1947 to unify air traffic.
RadioRadio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication.
RadarRadar is a system that uses radio waves to determine the distance (ranging), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations and terrain. The term RADAR was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging".
International Civil Aviation OrganizationThe International Civil Aviation Organization (ICAO) is a specialized agency of the United Nations that coordinates the principles and techniques of international air navigation, and fosters the planning and development of international air transport to ensure safe and orderly growth. The ICAO headquarters are in the Quartier international de Montréal of Montreal, Quebec, Canada.
European UnionThe European Union (EU) is a political and economic union of 27 member states that are located primarily in Europe. A supranational union with a total area of 4,233,255 km2 (1,634,469 sq mi) and an estimated population of just under 452 million as of 2026, its member states generated a nominal gross domestic product (GDP) of around €18.802 trillion in 2025, accounting for approximately one sixth of global economic output.
General aviationGeneral aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations except for commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes, ICAO uses a definition of general aviation which includes aerial work.
Separation (aeronautics)In air traffic control, separation is the concept of keeping an aircraft outside a minimum distance from another aircraft to reduce the risk of those aircraft colliding, as well as prevent accidents due to secondary factors, such as wake turbulence.Aircraft pilotAn aircraft pilot (or aviator) is an individual who controls an aircraft's flight by operating its directional controls. Other aircrew members, such as navigators and flight engineers, are also considered aviators because they assist in operating the aircraft’s navigation and engine systems. Aircrew members like drone operators, flight attendants, mechanics, and ground crew are not classified as aviators.
Military aviationMilitary aviation is the design, development and use of military aircraft and other flying machines for the purposes of conducting or enabling aerial warfare, including national airlift (air cargo) capacity to provide logistical supply to forces stationed in a war theater or along a front. Airpower includes the national means of conducting such warfare, including the intersection of transport and warcraft.*As an Amazon Associate I earn from qualifying purchases.
