EVALUATION OF A 100-WATT ELEVATED HIGH-INTENSITY RUNWAY EDGE LIGHT

The purpose of this project is to evaluate a newly designed, elevated, high-intensity runway edge light using a 100-watt lamp as its light source, rather than the standard 200-watt lamp, to determine if the lower wattage lamp and fixture combination would be satisfactory for category I and category II low-visibility operations, where a Federal Aviation Administration Specification type L-862 runway edge light fixture would be required. Pilot opinion during flight tests indicates that an installed group A version of the experimental runway edge light unit is visually adequate for category I weather operations and should be adequate for category II operations. Group A lights, however, did not meet the Office of Airport Programs Specification for L-862 runway edge lights (Advisory Circular 150/5345-48). An improved group B version will meet both requirements, since it satisfactorily passed the L-862 photometric specifications.
