Where are Touchdown Zone Lights (TDZL) located?

Where are Touchdown Zone Lights (TDZL) located?

• A. Along the entire length of the runway.
• B. In the airspace above the runway.
• C. In the touchdown zone, within the first 3,000 feet of the approach end.
• D. Only at the runway threshold.

Answer: (C)

Touchdown Zone Lights are placed on the runway surface specifically in the touchdown zone, which is the first 3,000 feet of runway beginning at the threshold. They provide a clear visual cue to help you identify where to touch down, especially in low visibility. They aren’t spread along the entire runway or in the airspace above the runway; they extend from the threshold outward up to 3,000 feet, not just at the very threshold.
