ABSTRACT:
A navigation aid for visually indicating to an aircraft pilot or other user the distance and bearing to a destination by use of radio navigation information from two pre-located sources. The axis of a compass rose representative of the destination is preset spacially and angularly with respect to the two radio stations, each represented by an individual compass rose longitudinally movable along primary elongate arms connecting the three compass roses. Three secondary elongate arms are pivotally movable about the respective compass rose axes. By setting two of the secondary elongate arms to represent the bearing of the aircraft to each of the radio stations, distance to the destination can be read directly from the intersection of the three secondary elongate arms. The desired bearing is indicated by the angular relationship between the compass rose centered about the axis representative of the destination and the secondary elongate arm pivoted about its axis.
