Research was conducted to evaluate the suitability of using Federal Aviation Administration (FAA) type L-852D taxiway centerline lights on curved taxiways at a nonstandard spacing distance of 25 feet. Typically, the type L-852D taxiway centerline fixture, when used on taxiways with radii between 75 and 399 feet, is spaced at 12.5 feet. The International Civil Aviation Organization (ICAO) uses a fixture that is designed specifically for curved applications that allows for a longer spacing requirement of 25 feet. New York's La Guardia Airport, in their Surface Movement Guidance and Control System plan being prepared for minimum authorized operations under 1200-feet runway visual range, proposes the installation of the FAA type L-852D taxiway centerline lights using the 25-feet spacing requirements of ICAO. The objective of this research was to evaluate the required longitudinal spacing for both the FAA type L-852D and ICAO taxiway centerline lights, considering notable differences in design, photometrics, and mounting orientation of the two fixtures. |
