1. A flight control system for an aircraft, the system comprising:

  • means for receiving command signals representing commanded values of a location of a geospatial point and a radius about the geospatial point for defining a circular groundtrack;

    means for determining a geospatial location of the aircraft and providing a location signal representing the location of the aircraft; and

    a controller for commanding flight control devices on the aircraft for controlling the flight of the aircraft, the controller also being configured to receive the command signals and the location signal;

    wherein the controller uses the command signals and location signal to operate the flight control devices to control the flight of the aircraft for directing the aircraft toward a tangent point of the circular groundtrack for intercepting the circular groundtrack and then generally maintaining a flight path along the circular groundtrack.
