This pad of forms is the same one we inlcude with our homestudy celestial nav
course. It includes 5 pages of complete instructions and examples of each, plus these forms:
- 40 samples of Form 104 (on 10 sheets)
— for sight reduction by Pub 249 or 229
- 20 samples of Form 106 (on 5 sheets)
— for sight reduction by the NAO sight reduction tables
- 10 samples of Form 107 (on 5 sheets)
— for noon sights (LAN prediction and reduction to latitude).
If you want our celestial course in the smallest possible nut shell, these forms would be it. The purchase of one set entitles you to
reproduce them for further personal use.
We draw your attention especially to Form 106 which we have designed for use with the NAO sight reduction tables that
appear in all copies of the Nautical Almanac as of 1989. This form makes the use of these tables almost as fast as conventional
inspection tables such as Pub. 229 or Pub. 249 — not quite, but almost. These NAO tables should be considered as a serious
viable option for sight reduction these days since in reality celestial is often a back-up to sight reduction by calculator, which in
turn is just a back-up to GPS.
With this reality in mind, there is a definite attraction to this approach to sight reduction, since you need only purchase one
book to cover all of celestial navigation, which you can in turn put in a plastic bag and stow till you lose the calculator or just need
to brush up.
These NAO tables are very popular with our students (even after learning with Pub. 249) and they will indeed do the job
well. I stress this because there have been magazine reviews of the NAO tables which berate them. Those authors, however, have
not taken the time to learn the tables, and they clearly have not had access to our forms, which are a vast improvement over the
Almanac's instructions. We provide a complete set of new (graphic) instructions with the forms. We agree the Almanac instructions
