Referring to FIG. 22, a diagram of a process 2200 for adjusting a trajectory profile is shown. The process 2200 can be performed by the flight management system 202 of FIG. 2. The process 2200 illustrates an example of modifying at least one aspect (e.g., the second segment 262) of the initial trajectory profile 232 by constructing a flight trajectory between a first waypoint of the flight plan 230 and a third waypoint of the flight plan 230. The process 2200 also bypasses construction of a flight trajectory between the first waypoint and a second waypoint of the flight plan 230. The second waypoint is subsequent to the first waypoint, and the third waypoint is subsequent to the second waypoint. Thus, the process 2200 constructs a trajectory that effectively removes (or ignores) a waypoint in the flight plan 230.

According to the process 2200, if waypoints are clustered so close together that each turn construction has an impermissible flight condition, the center of the waypoint cluster for all waypoints within one turn radius of each other is determined. A fly-over transition turn is constructed to that location, and the fly-over transition connects the inbound and outbound course and a course capture to the next waypoint. Thus, a virtual waypoint is added to the modified flight plan.

To determine whether a cluster is present, the distance between each waypoint is identified as being in an impermissible flight condition and previous and subsequent waypoints to the first and last waypoints are determined and compared to the turn radius. Waypoints that are within one turn radius of points (both before and after the cluster) are determined to be within the cluster.
