In-pavement Runway Guard Lights are a series of alternate-flashing yellow, unidirectional in-pavement lighting fixtures (L-852G) equally spaced along a runway holding position marking that are only visible to aircraft approaching the hold position from the taxiway side of the fixture. In some instances, however, problems have been encountered where pilots have reported the lights visible from the opposite side of the fixtures, i.e., to aircraft exiting the runway. This situation produced false information to the pilots that resulted in operational problems. The purpose of this effort was to determine the extent, cause, and solution for specific operational problems resulting from these runway guard lights installed at hold lines at the Chicago O'Hare International Airport. |
