Touchdown Zone Lights are characterized by which configuration?

• A. A single row of lights along the runway edge
• B. Approach lights
• C. Two rows of transverse light bars disposed symmetrically about the runway centerline in the runway touchdown zone
• D. Centerline lighting

Answer: (C)

Touchdown Zone Lights are arranged as two rows of light bars that sit across the runway, on both sides of the centerline, within the touchdown zone. These transverse bars run perpendicular to the runway and are placed symmetrically about the centerline, extending from about 100 feet beyond the threshold to roughly 3,000 feet down the runway. This configuration gives pilots a clear, visual cue to where the touchdown should occur and helps judge height and distance on landing. This differs from lights that run along the runway edge (edge lighting), lights that form the approach lighting system (which extend out toward the pilot before landing), or centerline lighting (which runs down the middle).
