VISUAL RANGE: CONCEPTS, INSTRUMENTAL DETERMINATION, AND AVIATION APPLICATIONS

A review is given about the principles, procedures, and instruments used in the measurement of visual range. The fundamental concepts of the visual range of objects and lights are discussed. The principles of operation of the several classes of atmospheric attenuation meters are reviewed and representative instruments are described. The course of development of the NBS transmissometer, its validation and application to aviation operations is reported. An error analysis is made of the effects of instrument errors and of differences in observer thresholds on visibility measurements.
