7/238902

Abstract:
A pair of transparent pressure sensitive stick-on film disks in the form of compass roses and a pair of transparent film VOR arms are removably attached to the center of the roses by cooperating male/female snap mechanisms. The VOR arms can be manually rotated to compass directions indicated on a VOR receiver and the cross-fix represented by the crossing of center-lines printed on the VOR arms represents the location of the aircraft on the map. Friction bearings associated with the snap mechanisms hold the arms in fixed positions after they have been rotated to the desired compass directions.
