In response to a congressional inquiry, the Federal Aviation Administration (FAA) Lighting Systems Office requested the FAA Airport Technology Research and Development Branch to conduct an evaluation of the effectiveness of an All-Strobe Approach Lighting System (ASALS) composed of 28 sequenced flashing lights for conveying required visual guidance information for a Category I precision approach. Contentions put forward by the developer of the ASALS are identified with special regard to the current standard for conducting Category I precision approaches, namely, the Medium-Intensity Approach Lighting System With Runway Alignment Indicator Lights (MALSR), which consists of 45 steady-burning lights and 5 strobe lights. The investigation consisted of assessing the validity of the vision science and performing flight evaluations of the new system. |
