Overall safety performance of the air traffic management system: Indicators and analysis

• We have applied Reason's Swiss Cheese Model to ATM system, following ESARRs.
• We have implemented APF in order to build safety indicators complying with international regulations.
• AHP has been adapted to ATM safety and two examples of safety indicators have been presented.
• Shewhart control theory is used to monitor and control safety indicators.

Defining means to assess safety performance and delve into their causes is one of the current and future challenges of the ATM sector. Following the experiences of the Aerospace Performance Factor by FAA and EUROCONTROL, this research aims to apply the Analytic Hierarchy Process (AHP) in order to build synthetic and user-friendly safety-related indicators. Through the analysis and combination of the safety events over time (accidents, incidents and issues), this model will pinpoint critical situations and will address the interventions of the decision makers.
