    The NA tables are currently the only tabular method taught as part of the United States Power Squadrons courses, on the theory that they are contained in a book you require anyway.  They have taught other tabular methods in the past, and still publish a Sight Reduction Methods "learning guide", which includes compact HO 211 (Ageton-Bayless), HO 229, and HO 249.

    maybe dr Kolb could boot the NA reduction and include Alan Bayless or S-Table.
    ​There is a perception that "nobody uses the NA tables" and so they should be replaced by something else. However, my feeling is that outside the rarefied ​halls of this list's discussions, the NA tables are widely accepted - and used!
