Tests were conducted in the FAA Fog Chamber to determine if backscatter from aircraft landing lights in visual ranges of 3 mi, 2600 ft, and 1200 ft would interfere with an observer's ability to see a set of amber target lights at the runway threshold. Results from a total of 518 test observations, made by 14 observers, indicate substantially no reduction in target-light visibility in visual ranges of 3 mi and 2600 ft. In the 1200-ft visual range, the visibility of the target lights was reduced by an appreciable amount.
