Overview of Taxiway Centerline Lead-On Lighting Project
 

Project Overview

The FAA has initiated a project to investigate a modified lighting configuration for taxiway centerline runway lead-on lights. This modification is designed to improve flight crews' awareness of the runway environment by providing an additional visual indication between the taxiway and runway environments. SDF has been chosen as a demonstration site for this proposal. Lens filters will be changed to conform with the proposed modification at selected intersections (see the airport diagram below) beginning late July 2004.

Under the current standard, the color pattern of taxiway centerline lead-on lights is all green, while the pattern for lead-off lights is alternating green and yellow. Under the proposed modification, the color pattern for both lead-on and lead-off lights would be alternating green and yellow.
