HUMAN FACTORS CONSIDERATIONS IN ESTABLISHING AIRCRAFT COLLISION AVOIDANCE SYSTEM ALERT THRESHOLDS

This paper discusses considerations that bear on the effectiveness of the pilot's use of collision avoidance alerts. The paper suggests that the human factors involved in the operational use of a collision avoidance system are as important in establishing alert thresholds as are the purely mathematical measures of false alert rate and late alert or missed alert rates. Collision avoidance commands are expected to occur infrequently. Consequently, the pilot's success in using his collision avoidance equipment to avoid a hazardous mid-air encounter depends upon his performance in a moment of surprise, and upon the attitude that he has developed toward this equipment prior to the time of the alert. The difficulties of assessing the human factors of collision avoidance systems under realistic conditions are discussed. Data from past experiments with collision avoidance systems, and operational experience with stall warning devices and the ground proximity warning system are reviewed. The advantages of conducting an operational flight test evaluation of a collision avoidance system before committing that system to implementation are discussed. /Author/
