Abstract : The runway visual range (RVR) for a Type L-850 bidirectional centerline runway light has been calculated for the red and white output ports at three different current settings for both day and night illuminance thresholds. The calculations are based on certain parameters measured in our laboratory on a sample light. The resulting RVRs are compared to the standard RVRs based on the High Intensity Runway light (HIRL). An analysis is also included on the error introduced by ignoring the spectral transmittance of the atmosphere. (Author)
