Conflicting Criteria in Evaluating Air Traffic Control Systems

Abstract

Sources of conflicting criteria in evaluating air traffic control systems include the multiple aims of air traffic control, the numerous performance measures for each task, incompatibility among behavioural, physiological and subjective data, the needs of man in contrast with those of the system, and individual differences. The extent of the conflicts may have been underestimated in the past, because certain relevant measures have been neglected. The solution requires greater awareness and quantification of these further measures and of the sources of conflict in evaluation criteria, plus practical acknowledgement of them in the initial specification of air traffic control systems.
