Chosen Problems of Air Traffic Control Systems Modelling

Air traffic control systems /ATC systems/ belong to the class of complex systems with hierarchical structure of control. ATC system consists of two main parts: Air Traffic block /AT block/ representing air traffic carried in the air space and Air Traffic Control block /ATC block/ which includes everything which concerns air traffic control, Air traffic is represented by a set of aircrafts moving in limited air space. Each air-craft is characterized by its specific technical characteristic. The structure of the limited air space is specified by adequate international law regulatins. Air traffic constitutes controlled plant. The control in ATC systems depends on controlling of the current traffic situation and making up appropriate decisions aiming at safety of all air flights carried on in the space being under control.
