The utility of information which would be provided by operational Pilot Warning Instruments (PWI) was studied experimentally in terms of the effect of PWI upon each stage of pilot activity occurring when a pilot is confronted by an intruder, viz., detection of the intruder, evaluation of the intruder threat, and the resulting avoidance maneuver. It was found that PWI improved the probability of detecting intruder aircraft. The extent of improvement was directly related to the amount of the information it provided. In addition, earlier detection, as would occur from PWI information, resulted in earlier evaluation of intruder threat and in earlier maneuvering, when necessary. Effectiveness in the operational situation would, of course, also depend upon such factors as closing rate and angle, range at detection, and aircraft maneuverability. (Author)
