    Re: NA sight reduction tables - a considered response from NavList to the NA office?

    Since we are discussing, at least tangentially, the size of the navigation computation equipment carried aboard, I am going to take this opportunity to plug my Flat Bygrave accompanied with the long term almanac from H.O. 249. The Flat Bygrave is only two pages, sealed in plastic, the almanac is only 4 pages and the forms are two more pages, total only eight sheets of paper in plastic protector sheets. All you need to make one for yourself is available here:

    I have attached two photos, one showing all eight pages spread out and the second showing them in a plastic case. The Bowditch is used for scale.

    Attached images show the relative sizes of Weem's, Pub. 208, NA, Kolbe LTA, 1981 Bowditch tables.

    BTW the Pentel P207 (anchoring all the tables) is one heck of a good mechanical pencil for plotting and chart work.

    See linked image which compares a Pub. 208 and Weem's sunline sight reduction for this morning. Both reductions fit on one side of an index card without the use of a form.
