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.
