The prediction of horizontal conflicts between aircraft on the basis of surveillance data may be enhanced if planned changes of aircraft's ground course are taken into consideration. Assuming standard turn manoeuvres the predicted flight paths and the horizontal distances are calculated as a function of time. The estimated constant wind component will strongly influence the appearance of the predicted flight profiles and the prediction of separation distances. The high resolution of the mathematical distance function is condensed by extracting particular conflict attributes which have been defined in terms of severity, urgency, dynamics, and duration. These data which describe the individual situation of a specific aircraft encounter, will build the primary basis for conflict evaluation. The evaluation process will be additionally influenced by secondary parameters which represent the situation of the considered aircraft in view of the surrounding air traffic, the air traffic control concept and technical systems, and the human controller. The result of this assessment methodology will be a 'measure of threat' which may be used by the responsible controller as an advisory aid.
