In addition to the above, as a result of the annual SMS maturity survey – „EUROCONTROL CANSO SMS Standard of Excellence Measurement 2024 BULATSA“, level D was reported for all 16 study areas (actually only the main 13 areas give the overall final assessment) except “Fatigue-related Risk Management” – level C, as well as for 2 additional areas (not affecting the final assessment) – sections of others (Transversal Study Areas) – “Human performance” and “Safety performance monitoring”. During the previous CANSO SMS 2023 benchmarking BULATSA’s Process of analysis, reporting and managing of aviation safety and technical events and occurrences, that ensures the effective management of all events that have the potential to impact aviation safety, is recognised as a GOOD PRACTICE.

The achieved overall result of 87% for the 2024 SMS maturity level survey ranks BULATSA among the top group of ANSPs from the European region with an overall score of C and a score of 86-90%.
