    Re: Great Circle Course via calculator & HO 208

    Bruce,

    FWIW, Celestial Tools The Sailings tool has a great circle mode, which, given the departure and destination latitudes and longitudes, calculates the initial course, distance, maximum latitude (and longitude at this latitude), and final course.  It will also list the latitudes and longitudes of points on the great circle route at even 5º increments of longitude, and the rhumb line course and distance between these points, and show the total rhumb line distance for comparison with the great circle distance.

    Example:
