    Re: HO 208 vs Compact NA tables.

    "Maybe but HO 208 is a whole lot easier to use." & "you will find pub 208 is the champ..."

    I agree with that! I like this sight reduction method and use it frequently just keeping up mentally. :-) 

    Since I couldn't get an original, and could not find printable quality copies (and did not like very much the original ordering of Table I.)  I made a printable A5 size booklet version for myself.

    I have made two significant modifications however: Table I is in Latitude order and use LHA (just print only those Lat pages that are needed) and Table II. is extended with a delta B column to accelerate interpolation. (and tried to better define the rules and incorporate them into the tables)


    (At the beginning there are refraction and other correction tables, the expalanation is at the end.)

    Since I do not make money on this, and the method is quite old, I do hope I don't breach any legal things.

    Who are interested, may give it a test run. It may be of interest for those who don't want to amortize their precious originals on the beach, too.
