Abstract:

This research seeks to define and estimate the frequency of aircraft interactions called conflicts which entail controller intervention. The task of conflict detection is viewed as a stimulus-response process in which the strength of stimulation is a particular closest-approach separation between aircraft, and the corresponding probability of response is the fraction of times controllers judge that separation to be a potential violation of the 5 nautical mile minimum separation standard. Data from human-factors studies of air traffic control are used to estimate response probabilities for a wide range of closest-approach separations. Two empirical models are derived for estimating the number of conflicts.
