    Re: Time diagrams

    When I learned  how to do “time sights”, I found the time diagrams to be essential.  Not so much when using 20th century pubs like ho229 or 249.  Perhaps they were much more important in the 19th century? And carried over into 20th century methods as an artifact? 

    Cheers

    Hello David Pike,  Thank you for your kind reply to my question.  It is as I suspected, though I still don't "understand" it.  I think my  two favorite nav texts are Mary Blewitt Pera's and Svend Simonsen's.  Both use  reasonably simple time diagrams as a basis for understanding what one is doing.  I find that in my collection of texts, the time diagram seems to be used in nav texts through (at least) the 80s.  But they have disappeared.  I think I understand what you said about using forms, but the several  sets of forms I've looked at that are availalbe on the internet seem confusingly complex to me...all sorts of little boxes and arrows.   I've always used a very simple form and, as I said originally, time diagrams.  Oh well, the world has passed me by in almost all ways, so I suppose this is just one more way.

    Thannks again fo your reply...and your humor.

    Cheers,

    John P
