Limits to growth: results from the detailed policy assessment tool [air traffic congestion]

Congestion-induced delay is one of the recognized metrics for assessing performance in the National Airspace System (NAS). Delay can arise from many causes, including factors specific to airline operations as well as factors that can be traced to NAS operations. In this paper we introduce a recently developed tool, the Detailed Policy Assessment Tool (DPAT), and use it to explore delay and the predictability of delay using some simple scenarios for NAS growth.
