The dynamic growth of air operations in the airspace is related to air traffic threats, which obliges aviation organizations to predict them and develop a proactive safety management strategy. The study aimed to analyze how the air navigation service provider (ANSP) implements the safety management system's assumptions in the event of a constant increase in air traffic and whether these activities contribute to achieving the assumed parameters (indicators) of safety. For this purpose, a critical analysis of the literature was carried out, supplemented with interviews conducted among these institutions' representatives. The best tools for implementing the safety management system's objectives, including hazard identification and risk management by ANSP, were identified. These are the safety assessment methodology for changes in functional systems SAM (Safety Assessment Methodology), the mandatory and voluntary reporting of aviation occurrences, and the RAMS risk assessment mark sheets. It should be noted, however, that the change management process concerns primarily planned changes. Simultaneously, there is insufficient information on how to deal with unplanned changes, and the safety culture requires intensified activities in the form of training of operational personnel. Besides, safety regulations require constant updating, and safety management models adapt to a continually changing environment.
