    Re: Mileage of rhumb line compared to mileage of great circle

    Hello Andrew,

    > but the rhumb line formula is more complex

    >What do you mean "more complex"? It is dist=60*(lat2-lat1)/cos(true_course)

    This is an approximation to RL, is mid-latitude sailing.

    Rhumb line or loxodrome in an WGS84, or other Earth model, is based in differential calculus, see the paper at my Web page: http://sites.google.com/site/navigationalalgorithms/papersnavigation/Sailings.pdf
