OPTICAL GUIDANCE SYSTEMS: ANALYSIS, DESIGN, AND DEVELOPMENT.
Abstract
Increased safety and reduction of the accident rate in carrier landing are of prime importance to the Navy. Believing that these objectives could be achieved only by a general increase in total system precision, NRL analyzed the landing configuration to locate the sources of present system inaccuracy. Insufficient display gain (sensitivity) and the accompanying lack of necessary derivative signals were found to be primary causes of system imprecision. To alleviate such problems, many new display schemes were accordingly conceived, developed, and experimentally tested. These include the Rainbow Optical Landing System and the Altitude Rate Command (ARC) System, which are high-gain direct displays of rate error information; and the Depth of Flash Optical Landing System, a highly sensitive display of error information presented so that the pilot can accurately extract rate or predictive information. Additional displays covered are the Laterally Compounded Fresnel Lens Optical Landing System, the Ten-fold Fresnel Lens Optical Landing System, the Shadow Box Optical Landing System, the Integrated Fresnel Rainbow Optical Landing System, the Audio system, the Phi Flash system, and several variations of a Depth of Flash system.
