Abstract : An evaluation of approach lighting for Category II operations was conducted. Tests were carried out in simulated and actual Category II weather conditions. Twenty-five subjects flying a DC-6B aircraft and seven subjects flying a Convair 880 aircraft participated in the weather simulation phase. Two subjects flying a DC-7 aircraft and seven subjects flying Gulfstream aircraft participated in the actual weather phase. Test results indicated that the following modifications to the inner 1000 feet of the United States Standard ALS would substantially improve approach success for high-performance aircraft in Category II operations. (1) Add red side rows of barrettes in line with the runway touchdown-zone barrettes. (2) Add a white cross-bar 500 feet from threshold between the rows of red barrettes. (3) Fill in the gap at threshold by continuing white-centerline and red-side-row barrettes to within 100 feet of the threshold. (4) Delete the red-wing bars 100 feet from the threshold. (5) Delete the condenser-discharge lights. It was recommended that a service test be conducted on the system at a major international airport having a high percentage of low visibility conditions.
