ABSTRACT:
An area navigation device automatically establishes waypoints along an RNAV course line intersecting with the four cardinal radials of VORTAC stations. For a given VORTAC station, the pilot selects any of the four cardinal radials and is automatically provided with the distance from the VORTAC station, along that cardinal radial, as the intersection with his selected RNAV course line. Thus, a pilot can quickly sequence through the cardinal radials and quickly ascertain the availability of waypoints along that radial. After an automatically generated cardinal waypoint is selected, it is automatically entered into memory dedicated to that waypoint for later recall and conventional use in area navigation.
