Runway touchdown zone markers are ________ that identify the touchdown zone of the runway. The AIM defines the touchdown zone as the ________ of the runway beginning at the threshold, and the touchdown zone markers are spaced ______ apart.

Runway touchdown zone markers are ________ that identify the touchdown zone of the runway. The AIM defines the touchdown zone as the ________ of the runway beginning at the threshold, and the touchdown zone markers are spaced ______ apart.

• A. Thin White Stripes; 3000 ft; 500 ft
• B. Thick White Stripes; 1000 ft; 1000 ft
• C. Narrow White Stripes; 6000 ft; 250 ft
• D. Thin White Stripes; 1500 ft; 750 ft

Answer: (A)

Touchdown zone markings identify the touchdown zone, which is the first 3,000 feet of the runway beginning at the threshold. These markings are white rectangular bars that run on both sides of the centerline and are placed at 500-foot intervals from the threshold, starting 500 feet from it and continuing to 3,000 feet. This setup gives pilots a clear visual cue of the usable landing zone on precision approaches. Therefore, the description that matches this is thin white stripes, spanning 3,000 feet from the threshold, with 500-foot spacing between the marks. The other options misstate either the width of the markings, the total length of the touchdown zone, or the spacing.
