ABSTRACT:
A course correction calculator for use in light aircraft includes two arms pivotally connected together and each independently pivoted over a map supported on a base. The pivot connecting the two arms is slidable longitudinally along one of the arms and the other of the arms is slidable longitudinally relative to one of two pivot points. A protractor is provided at the pivot connecting the two arms to indicate the angle between them and hence course correction when the two independent pivots are at the departure and destination points on the map and the mutual pivot is at the aircraft's position on the map.
