1. A digital map enabled flight management system (FMS), comprising:

  • a graphical flight planner (GFP) configured to define at least one flight pattern parameter and at least one flight pattern area associated with at least one aircraft;

    a digital map coupled to the GFP and configured to generate a first ordered plurality of n pattern points P(0) . . . P(n−

    1), each pattern point corresponding to a location within the at least one flight pattern area and to the at least one flight pattern parameter; and

    the flight management system (FMS) including one or more processors coupled to the GFP and to the digital map, the one or more processors configured to;

    generate at least one second ordered plurality of waypoints W(0) . . . W(x) based on (i) one or more of the first ordered plurality of pattern points, and (ii) a single search radius determined by a variety of contributing factors, two or more waypoints corresponding to a pattern point; and

    generate a single search pattern based on (i) two or more of the at least one second ordered plurality of waypoints, and (ii) a track space offset to separate at least one third ordered plurality of waypoints W(X)′

    . . . W(0)′

    from the at least one second ordered plurality of waypoints, the search patterm including the at least one second ordered plurality of waypoints connected to a portion of the first ordered plurality of n pattern points; and

    at least one display unit configured to display the at least one search pattern.
