Abstract : A simple replacement for the Fresnel Lens Optical Landing System (FLOLS) was designed and built at NRL for use as a research tool in the experimental testing of various landing aids. Called the Shadow Box Optical Landing System (SBOLS), the new system projects a beam pattern without the use of lenses and is designed to permit parametric variation for experimental purposes. In comparison to the FLOLS, the SBOLS is quite inexpensive, easy to transport, and simple to maintain. Experimental evaluation of two proposed landing systems, the Laterally Compounded Fresnel Lens Optical Landing System (LCFLOLS) and the Integrated Fresnel Rainbow Optical Landing System (IFROLS), both of which incorporate the FLOLS principle, was made feasible by the development of the SBOLS. Because initial flights with the experimental SBOLS verified its apparent optical similarities to the FLOLS, installation of SBOLS units on every runway at various naval air stations is suggested. Carrier pilots could then make training, practice, and even routine landings with the present shipboard type of system. (Author)
