    Re: Revised Nautical Almanac Concise Sight Reduction Tables

    Hanno,

    The three short log tables give Hc in under 3 minutes when starting with LHA, Dec, & Lat. An extra minute is needed for a Doniol Hc because of the single longhand multiplication. I have shelved the Nautical Almanac sight reduction tables along with Ageton tables. I found it very difficult to be mistake free two reductions in a row so have given up on both methods. Reduction times for Hc are about the same but result confidence is left wanting.

    Hi, Greg -
     
    RIC^3!

    How long did each reduction take you?
    Are you familiar with using NASR,? If so, how long would that
    take you?
