    Normally you don't do any interpolation when using the Air Almanac for flight navigation,  you plan your shots and take them on the ten minute  tabulated times. If you are off you can interpolate but the interpolation table is only tabulated for four second intervals since that is how long it takes for the GHA to change by one minute of arc.

     I think the bottom line is that the Nautical Almanac and Air Almanac give you GHA and Dec. accurate to ONE SECOND of time.  If you get your time hack from WWV it is hard to get time better than one second.

    Good enough for Goverment work.   :-)
