Abstract
This paper presents a Network Based Simulation Model developed with the objective of assessing novel safety performance indicators of the future Air Traffic Management system. A set of seven safety performance indicators is proposed based on Potential Safety Occurrences. Developed model contains three modules: separation violation detection module, TCAS activation module and risk of conflict assessment module. It was tested with planned flight trajectories crossing French and FABEC airspace during 24 h, covering several ATM improvement scenarios and different traffic demand levels. Results show capabilities to calculate certain safety performance indicators and to provide valuable safety feedback to traffic and airspace planners. Also, benefits of different ATM improvements to ATM safety performance have been estimated.
