Defining and Measuring Aircraft Delay and Airport Capacity Thresholds

This report provides airports and their stakeholders with guidance for understanding, selecting, calculating, and reporting measures of delay and capacity. The report describes common metrics, identifies data sources, recommends the most appropriate metrics based on user needs, and suggests ways to improve metrics. The report is divided into five chapters. Chapter 1 introduces the challenge of defining and measuring delay and describes the report’s organization. Chapter 2 discusses how delay is defined and used by various stakeholders, identifies sources of delay data, and describes how delay is calculated. Chapter 3 explains how capacity is defined and calculated and discusses the challenges of measuring capacity (including the interplay of how delay thresholds are used to set capacity thresholds). Recommendations for using the various definitions and measures of capacity and delay are provided in Chapter 4. Lastly, future trends for improving capacity and delay metrics, particularly for effectively communicating with the public, are summarized in Chapter 5.
