The NOTAM specifies sign codes used to tell ground personnel your destination on Wittman Regional Airport. You need one of these signs for your arrival and another for departure. Signs can be made with dark marker on a light background and should be clearly readable from a 50-foot distance.
If you prefer, these signs can be printed on your computer using one of the following files. Just pick the signs you need and be sure to have them in your airplane for the trip to Oshkosh. Have a great flight!
