SCIOTO VALLEY 99s
Air Marking Projects
The Scioto Valley Chapter of the Ninety-Nines uses the basic design of the compass rose prepared by the Air Marking Chairman of the North-Central Section of the 99s, revised March, 1988, from a design made earlier by the Three Rivers Chapter.
The Scioto Valley Chapter modified the procedure of the layout, but kept the design itself nearly unchanged. We made some minor adjustments in the logo of the interlocking nines for a more accurate rendition of the official logo, and re-depicted the logo within a rectangular grid centered on the origin of the compass rose. Also, we request the surveyor to mark magnetic directions every 30 degrees around the circle, eliminating some difficult geometrical constructions that were required when only the North line was surveyed.
The Scioto Valley Chapter has used these procedures since 1990, and has been quite successful in producing very striking compass roses at numerous airports in central Ohio, New Mexico, and Colorado.
Here is a list of the Scioto Valley Compass Rose projects to date:

The following documents are in PDF (Portable Document Format), and you may print copies of them if you wish. The margin settings in the documents should be satisfactory for most printers using letter-size paper when the page-scaling option is set to "None" on your printer setup page. If your printer cuts off some of the text, you may need to temporarily change the page-scaling option to: "Fit to Printable Area" (or similar option) on your printer setup page before sending the document to your printer.

Click here for a printable copy of the stencils. The Scioto and Valley stencils should be printed on separate sheets of paper and cut carefully with an X-Acto style of knife. You may need to print a current "year" stencil. The year page was created in Microsoft Word, using a landscape layout and minimum-allowable margins, with the type-font of "Stencil" at 325-point size.
