From
Dutton's, 15th edition (new this month): "...the LAN observation is extremely important in
navigation, chiefly because it can usually be relied upon to yield the most
dependable celestial LOP of the day. The Sun should be observed at LAN as
a matter of routine aboard every vessel.".
Why do
they make that statement in 2004? Especially naval authors writing for beginners
in the modern digital navy.

And this ties in nicely with the discussion we were having about "Old Nav v. New Nav". If you missed that, it's in the list archives and still fresh enough to join in. Noon Sun is really an "Old Nav" method, but because of its simplicity and the fact that it requires only a page or two of information instead of several pounds of tables and almanac, it may have a future that outlasts the "New Nav" that dominated the greater part of the 20th century.
