Abstract : This specification establishes design criteria for the Flight Plan Conflict Probe (FPCP), a part of the initial automation for the Advanced Automation System of the FAA's next generation air traffic control system. The algorithm provides data for a display to air traffic controllers whenever any two aircraft are predicted to approach each other within certain separation criteria in the horizontal and vertical dimensions. Such a pair of aircraft is called a conflict. Trajectory Estimation, another function of the Advanced Automation System, models the predicted position of each aircraft as a trajectory, consisting of points in (x,y,z,t) space and the line segments connecting them. Trajectories reflect both pilot intent (his approved flight plan) and current position (radar reports). FPCP automatically tests all trajectory pairs for conflicts. FPCP is designed to be compatible with current air traffic control procedures. It displays information early enough for controllers to resolve conflicts in a deliberate fashion. It alerts the the controller when prompt action is deemed necessary to resolve a conflict.
