Incorporation of uncertain intent information in conflict detection and resolution

Describes fundamental issues in conflict detection and resolution when intent information is available to the decision-maker. Different categories of intent (termed implicit and explicit) are defined and described in terms of aircraft automation. A model of conflict detection is presented that incorporates intent information and the probability that intent information is followed. Tactical and strategic conflict decision problems are described. In the strategic case, the need to consider both confidence in intent and criticality of intent is discussed. In the tactical case, the required amount of confidence in intent needed to prevent avoidance action is shown in a simplified example.
