    Re: AP terminology, WAS: 2-Body Fix -- take three

    Peter & Lu,
    
    We all agree on the definition of a fix, LOP, DR position, and EP.
    But if AP is not the generic word for the location of the apex of the
    St. Hilaire navigation triangle between the coH side and the coLat
    side, what is that location called??  Is there no generic word for
    it??  If we can't agree on the label for this point, let's call it the
    "controversial Point", the CP.
    
    Then, for List members, I can rephrase my favorite question:  Why does
    the St. Hilaire method use a CP instead of just calculating the LOP
    directly?  (I think Frank says there's no confusion on the answer to
    this question.)
    
    John
