    Re: USCG Student Example for Low Altitude

    Kermit, I come again back on what you mentioned previously: "... the
    refraction differences between US N.A. and French N.A. Tables reach 1
    full arc-minute by 0� observed height." I am still interested in
    finding out the formula they use for calculating their table values.
    Is there a sort of French version of the "explanotory supplement" and
    could it be that it is mentioned there?
    
    Salutations,
    Marcel
