Several transmissometer configurations using 250-foot baselines have been compared to develop a system with capability of measuring very low values of runway visual range. Tests were conducted at Atlantic City, N. J., and Arcata, California. The existing standard 500-foot baseline system was used as the comparison reference. The end-to-end dual system was considered most representative of the present standard. A single transmissometer system was judged to be less representative, primarily due to sampling differences.
