Gary- < I'll guarantee that they show a rhumb line but follow a Great Circle.> In hindsight that is not surprising. I suspect they display "here" plus "there" and then use a vector plot to calculate the line between them. I wonder, if you inserted a dozen waypoints and then had it show the course--would the line then reflect the Great Circle, at least to the extent of properly plotting the dozen course points along a "circular" broken line?
