Simulation Approach to the Resilience Engineering Assessment of the ATM System in Crisis Scenarios

THE increase of traffic density and typology of airspace users and aircraft operations increases the complexity of the current Air Traffic Management system and of its performance, and may lead to significant performance reductions in the presence of unexpected events. After the occurrence of an unexpected event, the analysis of Key Performance Area, such as capacity, efficiency, etc., and shortfalls in their related Key Performance Indicators at local, regional or network wide levels were made selecting the alternative scenarios and comparing them to the planned situation with normal operations. This relies on the working relationship and processes between air transportation network managers and operational Stakeholders especially during the anticipating, reacting and management phases strongly depending on their reactions to mitigate the impact on the system, and to optimize resilience in sector groups based upon the current Air Traffic Management activities. This paper describes an approach to resilience analysis in crisis scenarios, starting from the concept of Resilience Engineering and related metrics in Air Traffic Management system adopted in SESAR WPE2.21 SAFECORAM (Sharing of Authority in Failure/Emergency Condition for Resilience of Air traffic Management) project.
