    Bill,

    Here is a link to Gary LaPook's excellent web sight with the page explaining Landfall using a single LOP.

    https://docs.google.com/viewer?a=v&pid=sites&srcid=ZGVmYXVsdGRvbWFpbnxmcmVkaWVub29uYW58Z3g6M2I5OTVhMWZmMmI4ZDFiZA

    and an attachment.

    I also recommend reading Sir Frances Chichester's book " Seaplane Solo".

    Maybe not everybody ;-) When I started my bucket-list cel nav journey
    years ago with HO 229 the thought of using sunrise/sunset crossed my
    mind. After figuring out how to use the tables for a negative HC, I
    queried the discussion group. I was dissuaded from doing that, not
    because of extinction, but rather the flukey nature of refraction. It
    strikes me that if that was one of my first lessons, an experienced
    navigator would shy away from rise/set observations unless it was a
    court of last resort. Using that to locate a small island defies common
    sense IMHO.

    Back to the dumbest person in the room. I've followed the discussion
    with great interest. There appears to be another huge gap in my
    education. Would someone please expound on the "tested method of running
    down a Sun line" to reach a destination?

    Thanks

    Bill B
