ABSTRACT:
An aeronautic chart course and position locator is removably attachable by means of an adhesive backing to an aeronautic chart. The locator is made from a clear supple polymer film and comprises a 360 degree compass rose and a rotatable course and mileage indicator arm attached to the compass rose. The locator may also include a rotatable aircraft heading indicator disk for wind drift correction and course interception and permits course and azimuth identification to or from airports or VHF omni-directional range navigation radial (VOR) transmitters or any other selected point. Two locators can be used together with VOR equipment to locate the position of an aircraft on a chart by simple azimuth triangulation. A third locator can be used to determine the correct course to a point not serviced by directional radio facilities. A modified locator assists a student to visualize the aircraft's position on a chart either to the right or left of a given VOR radial. Another modified embodiment of the invention is used to display aircraft heading and azimuth with respect to one or more non-directional beacons. A pilot can use two of the modified locators with non-directional beacon radial equipment to locate the position of an aircraft on a chart by simple azimuth triangulation. Again, once the position of an aircraft is located, a third locator can be used to determine the correct course to a point not serviced by directional radio facilities. In all instances, the pilot is able to manage navigation using only one hand.
