Abstract: An aeronautical navigation plotting instrument is provided that includes a plotting frame and a compass rose attached to the plotting frame. The compass rose includes angular markings incrementally disposed thereon about a center of the compass for defining the angular orientation of the compass. A longitudinal slot is aligned with the center of the compass rose and extends through the plotting frame to define an opening for receiving a writing instrument. A plurality of first radial openings extends through the plotting frame to allow a writing instrument to extend therethrough. Each first radial opening is incrementally spaced from an originating opening in the plotting frame to form a plurality of incrementally spaced radial distances from the originating opening.
