    Re: Another "emergency navigation" sight reduction method

    I would appreciate being pointed to a message in the archives that oulines "the Bygrave formulas". 

    I try to search for them, and my problem is too many messages rather than too few.  There has been quite a lot of discussion of Bygrave on this list.

    I have found some formulae, but I have so far felt like I was coming into the middle of a discussion...and having a little trouble getting understanding what has gone before.  I find elements in the formulae that are referred to by their standard abbreviation...but I don't know what the symbols refer to.

    I am familiar with the sine cosine equations that stand behind the Ageton.  I would love to expand my horizons.

    Thank you very much,
