Some Human Factors Aspects of Computer-Aiding Concepts for Air Traffic Controllers

Abstract

This paper sets out the basic philosophy of a developing program of computer-aiding concepts for the controller's decision making. A brief review is given of early work on the computer-assisted approach sequencing (CAAS) concept for a major airport, and the main topic is the interactive conflict resolution (ICR) concept for assisting the en route controller in conflict detection and resolution. ICR is a predictive aid used interactively by the controller; the concept is described in detail. A real-time simulation experiment is reported, in which each of three pairs of controllers acted as an executive/support team in handling traffic samples in a busy sector. Objective records and subjective data suggest the effectiveness and acceptability of ICR. Further research on the controller's activities within, and attitudes toward, computer-based tasks is outlined.
