    Brian, you wrote:

    '...I do prefer using Norie's Haversines method the best followed by H.O.229. In short, I feel its good to have both a DR method and an AP method in your arsenal for your navigational adventures. '

    Maybe worth acknowledging that the haversine method can just as easily use an AP as a DR, and although the intercepts will almost certainly be larger, for all practical purposes the same LOP will result. Using an assumed position with the haversine formula (or a calculator) also makes for simple, whole degree lat and LHA table entries.

    Regards

    John
