    Re: Longitude by Time Sight Using a Slide Rule

    I'm a Floridian now Alan. Florida has its share of virus issues too. The circular rules are more accurate but won't quite get you to the needed 4 place precision. A natural sin cos 1' table and the Otis King cylindrical slide rule will get it done.
