ABSTRACT:
An optical system for guiding the pilot of a ground-maneuvering aircraft towards a parking bay has, an illuminated target positioned behind a fixed stop aperture along a line of sight of the pilot which is inclined to the direction of approach of the aircraft to the bay. As the aircraft advances different areas of the target come successively into sight by parallax, and these may be differently colored to indicate the correct stopping position and also whether the aircraft is to the left or right of the correct approach line.
