Has anyone tried the book �The Calculator Afloat� by Shufeldt, published by
Navel Institute Press? It has both the formulas to use in your own
programming and step by step instruction for using calculators to solve the
navigation triangle. It also has solutions to many types of plane sailing,
rumb line sailing, great circle sailing, wind and current problems etc, etc.
That book and a copy of ICE should go a long way towards independence from
the printed tables. By the way the book also has a formula for a long-term
almanac of Aries and a star almanac, but I have not tried that one out, I
have used ICE.
All the best,
Robert Gainer
