L-853 Cylindrical Runway and Taxiway Retro-reflective Markers Study

The following report describes an evaluation of the L-853 cylindrical retro-reflective markers that are used on airports to increase night identification of runway edges, centerline, and taxiway edges. The evaluation was performed to determine if increasing the standard size would improve the markers' conspicuity to aircraft and ground vehicles and to determine if the location of aircraft mounted landing lamps have any effect on the visibility of the retro-reflective markers.
