Linear LED AirfieldLighting

The objective of this project is to gain an understanding of the potential benefits of linear Light-Emitting Diode (LED) lighting systems to the spatial orientation of airfield users, including pilots and ground vehicle operators through field testing experimental arrangements of linear LED lighting systems on the Ohio State University Airport and, in later phases, other airports within the Partnership to Enhance General Aviation Safety, Accessibility and Sustainability (PEGASAS) system of universities. A series of laboratory and controlled field experiments conducted by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute demonstrated that visual acquisition times for different simulated taxiway/runway intersection configurations could be reduced by using linear source elements in place of discrete point source elements when they are spaced equally. Conversely, linear elements could be placed further apart than point sources in order to maintain visual acquisition times. The LRC developed and validated a model to predict relative visual acquisition times under delineation configurations with different element lengths and spacing. In order to provide further face-validity, this project proposes field experiments be conducted to characterize responses to linear element delineation along a real-world airfield. The project proses that field experiments to be initially conducted at The Ohio State University (OSU) Airport. The Linear LED Lighting Project includes the following phases: Literature review, creation of test site at the OSU airport, testing methodology and data collection, and data analysis and reporting. The primary objective of this research is to provide validation to the previous studies conducted by LRC. Given the difference between the laboratory environment found at LRC and the airport field test environment at The Ohio State University Airport, this research will provide results that provides comparable analysis of the accuracy and reaction times of test subjects viewing linear LED lights of varying lengths and spacing in varying taxiway centerline configurations. It is expected that this research will provide the following benefits: A validation of previous LED perception studies conducted by LRC, a greater understanding of the perception of linear LED lighting systems to airfield users, and guidance for the FAA towards determining standards for linear LED lighting systems on public use airfield.
