1. A method of generating and displaying a release point for a flare capable of being deployed by an aircraft, the method comprises:

  • inputting into a computing device a planned midpoint of a planned burn track of the ignited flare corresponding to a geographic coordinate;

    inputting into the computing device flare parameters for the flare capable of being deployed by the aircraft;

    inputting into the computing device wind parameters including a wind direction and a wind magnitude for a given flare ignition altitude;

    inputting into the computing device a flare drift distance and a flare drift direction for the given flare ignition altitude;

    inputting into the computing device aircraft parameters including an aircraft speed and an aircraft direction;

    generating by the computing device a flare drift vector based on the flare parameters, the wind parameters, the flare drift distance, the flare drift direction and the aircraft parameters;

    calculating by the computing device a midpoint of the flare drift vector;

    determining by the computing device a release point of the flare such that the planned midpoint of the planned burn track of the ignited flare coincides with the midpoint of the flare drift vector; and

    displaying the release point on a navigation display of the aircraft capable of deploying the flare relative to a real-time navigation map.
