ABSTRACT:
A path indicating apparatus for indicating a path so that a moving vehicle movable in the horizontal and vertical directions, such as an aircraft, may move along such a predetermined path. The predetermined path is defined as an intersecting line of two scanning planes which are formed by scanning signals having a narrow beam width in a horizontal plane and a vertical plane, respectively. The vehicle is provided with a plurality of detectors arranged in the horizontal and vertical directions for detecting the signals being scanned in the horizontal and vertical planes, respectively, so that the detectors arranged in the vertical and horizontal directions may detect deviation of the vehicle in the horizontal and vertical planes, respectively. The vehicle is responsive to the detected signals from the respective detectors to determine the moving direction to be taken by the vehicle so that the vehicle may move along the path and the vehicle is steered responsive to the determined direction outputs.
