    Re: Classic Trig Log Sight Reduction Revisited

    What I like about the log sin/cosine tables is that it perfectly complements the slide rule, and pocket trig calculator using the same formulae and DR assumed position. Pub 208/Weems, Pub 249, Pub 229, Pub 214 all complement each other using an assumed position to get a whole LHA and Latitude. The Ix diagram is a one page time saver for Pub 208, Pub 211, Weems, and Trig Log tables (no reason not to include it).

    Kolbe LTA used log sine/cosine in earlier version, something i really liked.
    I would use Hanno´s graph for quick azimuth calcs though.
    Qctually like Bygrave +Hanno graph or Weems LOP+Hanno graph if speed and weight are concern.
