A Bright Idea

Research shows that changing the color pattern of taxiway centerline lead-on lights heightens runway location awareness. This article examines a project designed to evaluate laboratory simulation studies and field demonstration that tested the effectiveness of taxiway centerline lighting scheme color pattern. The research found: in a simulation study, more than 90% of the participating pilots thought the proposed modification should be implemented; in a field demonstration more than 70% of the surveyed pilots thought the modification should be implemented; not all pilots fully understand airport surface lighting; additional training about airport surface lighting is suggested to all pilots; no operational problems were found; and, the modification of taxiway lead-on lights did not impact aircraft taxi speed.
