Abstract:

This project was undertaken by the Federal Aviation Administration (FAA) Airport Safety Technology Research and Development Sub-Team as part of an effort to determine the relative conspicuity, from an aircraft on approach, of Type I and Type III retro-reflective beads. Retro-reflective beads are designed to redirect and return light back to its source. The inclusion of retro-reflective beads in painted surface markings can increase their conspicuity. It has been suggested that Type III retro-reflective beads, which have a higher index of refraction (IOR) compared to Type I beads, will substantially increase the conspicuity of paint markings and could help prevent runway incursions. The FAA uses Federal Specification TT-B-1325D, “Beads (Glass Spheres) Retro-Reflective,” to specify retro-reflective beads.
