Developing metrics for operational resilience performance of European airports

●concept of “resilience” has become a buzzword ●this study: focus on operational application within operational ANS at airports ●allows for the specification of nominal / non-nominal performance thresholds ●within Europe, disruptions more prominent for departure process and turnaround (dependency) ●direct correlation between capacity utilisation, impact level, and recovery time for higher capacity utilisation quotas (requires better planning) ●lower utilisation / schedule buffers are not always used efficiently to recover from disruptions.
