Why don't y'all just ask the dock master where you are?

In aircraft they ask for a "practice" DF steer.

So we have spoken of ancient navigational tools. The calculations that are associated with those tools confuse me. Has anyone been able to divide roman numerals? I am very thankful for the hindu-arabic numeric system especially since they added the "0".

You're dating yourself, Fred. The DF Steer went the way of the dodo bird with the contracting of the Flight Service Station responsibilities to Lockheed Martin.

They are all greek to me.

Those fellows did not use "roman numerals" they used ionian numbers which in fact were greek letters representing numbers. Even more confusing when one would try dividing or multiplying, I would imagine.

If you want to read about the early, pre-1400, development of longitude and latitude positioning using lunar observations pick up a copy of "1434" by Gavin Menzies. Much research is discussed into the contribution of Toscanelli, Alberti, and Regiomontanusee. These early mathematicians shook up the Greek "flat earth" and the earth is at the center of the universe crowd.

You might also look at "Beyond the Blue Horizon" by Brian Fagen. An archeologist at UC Santa Barbara, Fagen is the author of many books, including The Cruisers Guide to Southern California. He explores how early men were able to find and explore unseen lands.

Love reading and learning all this stuff. Really, really love turning on my electronics and having it done for me, far more accurately than the best I ever did with the sextant!
