    Re: Traditional navigation by slide rule

    Hi Francis,
    In the antiquated world of slide rules, there were no decimal places on the C and D scales. One of the first things you had to learn was how to estimate and where to place the decimal place.

    ( I'm tempted to expand on this but that would just dilute the basic answer. - - - Arrgh ! I can't stop myself! I think that estimating and thinking about the answer helped with understanding as opposed to plugging numbers into a computer program and assuming that the computer is correct. Now I'm done. )
    Regards, Noell
