Air Traffic Services - ATS

The area of responsibility of Belgocontrol ATS (Air Traffic Services) comprises the Brussels FIR/UIR up to FL 245 (Flight Level 245 = 24500 feet, that is approximately 8000 meters), including, according to bilateral agreements, parts of foreign adjacent countries. The responsibility for the provision of civil ATS in the airspace above FL 245 has been delegated to Maastricht Upper area control centre (MUAC). Brussels ACC also controls the airspace over the G.D. of Luxembourg between FL 145/165 and 245.

The Brussels FIR/UIR is divided in several subareas, controlled by different units. The Military airspace is controlled by the Air Component of the Belgian Defense.

The following TMA (Terminal Maneuvring Area) and CTR (Control Tower) are managed by APP (Approach), ACC (Air traffic Control Center) and TWR (Tower) located at the main airports.

Air traffic services consist of three tasks

  • Air traffic control : Air traffic control consists of a system of people and equipment that ensures aircraft a safe flight. Air traffic controllers coordinate the movement of air traffic to make sure that separation standards between aircrafts are being respected. The goal of air traffic control is to minimise the risk of aircraft collisions while maximising the number of aircraft that can fly safely in the same area at the same time. Air traffic control is split up into area control, approach control and aerodrome control.
  • Flight information service (FIS): The flight information service provides information to pilots that are vital to the safe and efficient conduct of their flight, and includes information on other potentially conflicting traffic.

    Flight Information also includes:
    • Meteorological information;
    • Information on aerodromes;
    • Information on possible hazards to flight.
  • Search and Rescue (SAR) service : The purpose of alerting is to warn the authorities concerned on aircraft needing assistance in the form of search and rescue and to assist these authorities if needed.
