The report describes testing of airport lighting systems in day and night fog conditions utilizing a very large chamber and producing fog by compressed air and water through nozzles installed along the side of the chamber. The test results reported are those for restricted visibility conditions defined as Category II, wherein the visual range was 1200 ft. Peak candlepower values and photometric distributions required for Category II operations were determined during the tests covered by this report. Various patterns of lights were installed on the floor of the chamber and simulated approaches and landings were made through the fog using a total of 36 experienced pilot observers. The observers rode in an airplane cockpit suspended from overhead rails. The tests showed that present visual aids could be considered adequate, although marginal, for Category II operations at night. In day time fog, however, the higher background brightness had a profound effect and made some of the standard components inadequate. (Author)
