    Sure. If your destination is generally northeast of you then Zn = Az;
    If your destination is generally southeast of you then Zn = 180 - Az;
    If your destination is generally southwest of you then Zn = 180 + Az;
    If your destination is generally northwest of you then  Zn = 360 - Az.

     Gary, do you have azimuth-rule suggestions for
     rhumb line calculations?  It seems likely that if I got
     azimuth wrong for great circle routes, I may well have
     gotten my rhumb line calculations wrong as well.Bob
