Chart formula - navigation question

[QUOTE=Tugboattim;69483]We have that formula in an excell sheet, it gives you the intercepts, Iv never used it though, way point for windows does the job just fine you can get the lat or long per degree or 2,5,10. Just use that and go to the.next charts. Send me your email and I could send the excel sheet to you[/QUOTE]

I’d like to have that spreadsheet - my email address is my user name without the space at gmail.com
