Threshold markings stripes indicate runway width: A runway width of 75 feet uses how many stripes?

• A. Four Stripes
• B. Six Stripes
• C. Twelve Stripes
• D. Eight Stripes

Answer: (B)

Threshold markings give pilots a visual cue of the usable width at the start of the runway. The number of stripes across the threshold is tied to the runway’s width, providing a quick reference on final approach and rollout. For a 75-foot-wide runway, the standard pattern uses six stripes—three on each side of the centerline. This symmetric arrangement helps the pilot quickly gauge width, especially in reduced visibility. If the runway were wider, more stripes would be used; if narrower, fewer stripes.
