    Re: Nories tables vs H.O. table's
    From: Nigel Gardner

    When I worked for the Queen more years ago than I care to remember we were
    issued with AP 3270's (the same as HO 249). The three volumes weighed about
    10lb, were bulky and were issued to us and not the aeroplane. By the time
    you had those, a sextant, an almanac, bunch of charts and various other
    pubs to carry around (not to mention a parachute) things got a bit
    overladen.
    
    To cut a long boring story short I left the AP3270's in my locker and
    managed to get round a fair bit of the world using Hughes tables which
    weighed just over a pound. Rearding accuracy, the tables themselves were
    readable to a tenth of a minute but as an air sextant could only be
    interpolated to the nearest half minute that was a bit academic, although
    more reliably accurate than AP's
