According to one implementation, modifying the at least one aspect of the initial trajectory profile includes translating a turn center for a second turn within the initial trajectory profile until an end of a first turn within the initial trajectory profile is coincident with a beginning of the second turn. According to another implementation, modifying the at least one aspect of the initial trajectory profile includes translating a turn center for a second turn within the initial trajectory profile along a path parallel to a line between a first waypoint of the flight plan and a second waypoint of the flight plan. According to another implementation, modifying the at least one aspect of the initial trajectory profile includes translating a turn center for a second turn within the initial trajectory profile along a path parallel to a line outbound from a second waypoint of the flight plan. According to another implementation, modifying the at least one aspect of the initial trajectory profile includes adding a co-tangent straight segment at one or more points tangent to a first turn arc and a second turn arc based on a first waypoint overfly transition intercepting a first waypoint outbound course closer to a second waypoint than to a beginning of a second turn.

According to one implementation, the method 3400 includes determining whether at least three bypass waypoints are included in adjacent legs of the flight plan. The method 3400 may also include in response to a determination that at least three bypass waypoints are included in the adjacent legs, determining whether more than two bypass waypoints of the at least three bypass waypoints are located within a particular turn radius. The method 3400 may also include grouping the more than two bypass waypoints based on a centroid of the more than two bypass waypoints.
