Abstract
A flight management system device and method. The method includes determining a ground track for a flight leg based on a spherical earth model. The flight leg includes two waypoints that are specified with an ellipsoidal earth model. The method includes determining that a parameter associated with the ground track exceeds a threshold. The method includes inserting an anchor point between the two waypoints on a geodesic to effect a course change to the ground track between the two waypoints such that an intended flight path is within specified thresholds. The geodesic is associated with the ellipsoidal earth model. The method includes modifying the ground track to include two spherical earth model path segments spanning from the first waypoint through the anchor point to the second waypoint. The two spherical earth model path segments are computed based on the spherical earth model. The method includes storing modified ground track data.
