A processor-implemented method for an aircraft to receive and process weather data and traffic data to identify a number of feasible target traffic for a paired approach for the aircraft, the method comprising: generating a trajectory of the aircraft as a function of received aircraft state data and weather data; determining that the aircraft is entering a terminal radar approach control, TRACON, airspace; filtering, by a processor of the aircraft, the received traffic data to identify a plurality of neighbor traffic that are entering the TRACON airspace or are within the TRACON airspace when the aircraft is entering the TRACON airspace; estimating, by the processor, concurrently, for each neighbor traffic of the plurality of neighbor traffic: a trajectory, a traffic arrival time at a location for a respective paired approach with the aircraft, a spacing interval between the neighbor traffic and the aircraft for the respective paired approach, and a respective target location for the aircraft to begin the respective paired approach, as a function of the spacing interval; identifying, by the processor, the number of feasible target traffic as those neighbor traffic for which the aircraft can achieve the respective target location within a prescribed amount of time, based on a current speed of the aircraft; identifying, when the aircraft is not permitted a speed change, infeasible target traffic as those neighbor traffic for which the aircraft cannot achieve the respective target location within the prescribed amount of time, based on the current speed of the aircraft; and presenting on a display unit, a lateral image for viewing by a pilot of the aircraft, the lateral image having each feasible target (302, 304, 306, 308) and each infeasible target (310, 312, 314, 316) indicated with a respective icon depicting a location, a heading and distinguishing its feasibility or infeasibility. generating a trajectory of the aircraft as a function of received aircraft state data and weather data; determining that the aircraft is entering a terminal radar approach control, TRACON, airspace; filtering, by a processor of the aircraft, the received traffic data to identify a plurality of neighbor traffic that are entering the TRACON airspace or are within the TRACON airspace when the aircraft is entering the TRACON airspace; estimating, by the processor, concurrently, for each neighbor traffic of the plurality of neighbor traffic: a trajectory, a traffic arrival time at a location for a respective paired approach with the aircraft, a spacing interval between the neighbor traffic and the aircraft for the respective paired approach, and a respective target location for the aircraft to begin the respective paired approach, as a function of the spacing interval; identifying, by the processor, the number of feasible target traffic as those neighbor traffic for which the aircraft can achieve the respective target location within a prescribed amount of time, based on a current speed of the aircraft; identifying, when the aircraft is not permitted a speed change, infeasible target traffic as those neighbor traffic for which the aircraft cannot achieve the respective target location within the prescribed amount of time, based on the current speed of the aircraft; and presenting on a display unit, a lateral image for viewing by a pilot of the aircraft, the lateral image having each feasible target (302, 304, 306, 308) and each infeasible target (310, 312, 314, 316) indicated with a respective icon depicting a location, a heading and distinguishing its feasibility or infeasibility.
