ABSTRACT:
An apparatus for providing lateral guidance through a plurality of waypoints utilizing curved path transitions. When the curved path transitions overlap due to a short leg there is a discontinuity in the desired path of the aircraft, causing the aircraft to experience excessive and oscillatory bank angles to maneuver through the turn. The invention adjusts the transition parameters so that there are no discontinuities in the flight path by computing a new turn radius, turn center, or turn center coordinates, in accordance with the course through the waypoints. The invention determines which flight plan legs are short and calculates the parameters so that the path will not violate air space boundaries and bank angles will be minimized. A circular path is generated tangential to course changes in the same or opposite direction, irrespective of the value of the flight plan leg length.
