    Re: Additional corrections to the sextant altitude in air navigation

    On April 11 you posted a message with a link to AFPAM 11-216, which  
    at the time worked ok.  I saved it for later use, but now I see the  
    page no longer exists.  Therefore, I would very much like to receive  
    the PDF download from you.
    Regarding corrections for flight navigation, you did not mention  
    Rhumb Line Correction.  At 500 knots over the North Atlantic, this  
    correction is about equal to the coriolis correction.  It is additive  
    to coriolis  going one way, and almost cancels it out going the other  
    way.  I forget which way does what.
    I am surprised that no one asked what the Polhemus Computer is.  We  
    used to sell them in the 70s, but stopped when we got to where the  
    carrying cases were cracked and the staples in the instruction  
    manuals were rusted.  We have at least 100 of these left in storage  
    If anyone wants one, they can email me off line.
