    Re: Polar navigation

    Hi Peter
    From Dutton's Navigation and Piloting, 1972.  Article 4213
    "One special method of plotting lines of position is available only in polar 
    regions. Byt this method the pole is used as the AP ...  This method was 
    first suggested at least as early as 1892, but there is no evidence of its 
    having been used until some 30 years later. In the early days of air 
    exploration in polar regions the method was quite popular, but with the 
    develpoment of modern tabular methods, it has fallen into disuse, except 
    within 2 degrees of the pole."
    Dutton goes on to state that the method will be accurate for meridian 
    alititudes at any latitude, as a special case.
    Dutton gives about 20 pages to special techniques used in the polar regions.  
    Hope this helps!
    Best Regards
