Expanding the Scales of Universal Plotting Sheets

Universal plotting sheets are used in celestial navigation and marine weather routing. We discuss here how to expand the base scale of 60 nmi per printed parallel of latitude to 30 nmi and to 6 nmi. For reference see the article at https://davidburchnavigation.blogspot.... Universal plotting sheets are available at https://www.starpath.com/catalog/acce.... Our cel nav book explaining more details of the use of these plotting sheets is at https://www.starpath.com/catalog/book... and the sextant data shown is from the book Hawaii by Sextant, https://www.starpath.com/catalog/book...
