    The Power Squadron has a method of teaching celestial navigation where the first year is the practice and the second year is the theory. Those students who only want to know how to do it don't have to suffer through all the whys. I can only surmise that it evolved in response to student desires.

    In his training video Bill Buckley stated that the failure of many earlier attempts to teach CelNav rests in that they also explained WHY it works, instead of just HOW it works.
    For me personally, this cookbook approach did not work very well - but then, I sit behind a desk contemplating the math behind it all, while they used it in real life.

    Captain Lane was famous for saying that all the math classes he took after high school never did him a bit of good, and spherical trigonometry was of no value in understanding celestial navigation (!).

    "in UNDERSTANDING Celnav ..." : not really necessary, I buy that one.
    "and in computing then ???" : maybe spherical trigonometry might be useful - oh !!! just a bit, only - now and then, no ???
