    Re: Hanno Ix azimuth diagram flowchart?

    RTFM is how computer developers say 'read the _____ manual', often to the end-user.

    But this is somewhat to the point - the Hanno Ix chart doesn't really have a clear 'manual' of instructions that can be followed (or at least I haven't been able to find one). Nothing explicit like the haversine formula instructions, where, for example: 

    if Latitude N:
     if LHA > 180°, Zn = Z
     if LHA < 180°, Zn = 360° − Z
    if Latitude S:
     if LHA > 180°, Zn = 180° − Z
     if LHA < 180°, Zn = 180° + Z
