Evaluation of Airfield Lighting Circuit Performance

New requirements for airfield guidance signs have necessitated replacement and purchase of a large number of airfield signs. In the process manufacturers have developed new designs for airfield signs using current technology for the illumination and control. However, as the new signs are placed into service, airports are experiencing problems with the performance of the signs. In order to determine the scope and to investigate these problems, the Federal Aviation Administration (FAA) conducted an evaluation at six different airports. The evaluations showed that the source of the electrical problems was the incompatibility between the signs and the constant-current regulators. The report provides recommendations to improve the operation of airfield lighting circuits.
