Measuring and monitoring resources in the National Airspace System NAS is a key activity of Federal Aviation Administration FAA operational managers. Airports and associated terminal areas are complex systems and require a number of metrics to properly characterize performance. In this document, 13 performance measures are described, in three different categories 1 flow efficiency, for both taxiing and airborne flights, 2 runway utilization, for both arrivals and departures, and 3 rate of flights not cancelled or diverted, for both arrivals and departures. These 13 metrics capture performance in the different stages of flight from push-back to gate arrival. Sample calculations and use cases are presented, using Chicago OHare International Airport ORD as a subject airport. The multiple measures may be combined for an omnibus metric, for quick assessment of performance at that airport, in a next-day review context.
