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.
