    Silicon Sea Nav Problems
    From: Dan Hogan

    ALL,
    After a short discussion amoung the working group, I am wondering if the
    list pareticipents are aware that usin a Nav Log will ease working the
    problems. The idea is that entries are made as if on a boat and any mistakes
    are visible on one page, The log layout will depend on what DR and celestial
    method you are using. Most will require at least the data in the following
    sample. An 8 1/2 x 11 spiral binder is ideal/notebook.

    A one page per problem log can be developed by laying out SR in a columner
    format. Allowing three sights per page below the DR. That is for all but the
    formal format for 229.
    But 229 can be shortend once one is familer with it by combining the
    tabulated corrections. Also just use Left page for DR and Right page for SR.
