Threshold markings stripes indicate runway width: A runway width of 150 feet uses how many stripes?

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

Answer: (A)

Threshold markings give a quick visual cue of how wide the landing area is. The stripes across the threshold are counting signs: their total number grows with runway width, so pilots can judge width at a glance. For a runway that is 150 feet wide, there are six stripes on each side of the threshold, making twelve stripes in total. This symmetrical pattern helps identify a 150-foot-wide runway even when visibility is limited. If the runway were narrower, there would be fewer stripes; if wider, more stripes would appear.
