    >I am attaching several excerpts from the Air Almanac and H.O 249 Volume 1 
    that can be used to see the differences in flight navigation practice 
    compared to surface navigation. From the Air Almanac is the daily page for 
    July 1, 1992, which is actually printed back to back on one page of the 
    almanac. This shows the P in A  table for the moon which changes based on the 
    distance of the moon from the earth on a particular day. Also from the Air 
    almanac are the dip, refraction and coriolis correction tables.

     From H.O. 249 is the page for zero latitude and LHA aries from 180 to 
    359º for epoch 1980.
    Also attached are the MOO and MOB tables for 4 and 1 minute periods and 
    the interpolation table for same. The table for correction of precession 
    and nutation is also attached.
    
    These provide you with all the information you need to work a three star 
    sight with an assumed latitude of zero, an LHA aries between 180 and 
    359º on July 1, 1992.
