Can Linear Light Sources be Beneficial to Pilots?

Presently, lighted delineation for runway and taxiway airfield systems uses discrete light sources in the form of raised and in-pavement light fixtures varying in color to indicate edges and centerlines of runways and taxiways. There have been suggestions both anecdotally and in published literature, that delineation practices using more continuous visual elements might provide superior visual cues to pilots navigating on the airfield than the primarily discrete visual elements used in the form of edge and centerline light fixtures. To assist the Federal Aviation Administration (FAA) in assessing the potential benefits of more continuous or linear visual delineation of runways and taxiways, a series of laboratory and field experiments was conducted by the Lighting Research Center (LRC). The primary objective was to investigate the influence of the length and spacing of delineation elements on visual acquisition under simulated airfield viewing conditions, including both static and dynamic situations.
