    Yes Brad.

    In a this GC route,(with 20 kt and change of course every hour), the change in course between two tracks is negligible, only in the vertex, the change of curvature of the GC may be important.

    To take into account several changes of course/speed the easy way is to calculate the change in latitude and in longitude for each track, add all this increments, and calculate with them the new course and speed, like in piloting with DR. Using them for moving the Lop.

    Good winds and regards,
