How many threshold stripes does a runway 45 m wide have?

A runway that is 45 meters wide typically has threshold stripes that are painted to ensure visibility for pilots upon approach and landing. The orientation and size of these stripes are standardized in aviation to maintain consistency and safety across airfields.

According to international and UAE aviation regulations, the threshold stripes consist of white rectangles. For a runway width of 45 meters, the number of stripes is determined by the width of each individual stripe and the space allocated for the stripes.

In this case, a standard guideline indicates that for runways of this width, specifically, there would be 12 stripes across the threshold. Each stripe is designed to provide optimal visibility, aiding pilots during landing and takeoff by marking the start of the landing surface.

The configurations for other widths are different, which is why the specific number of stripes correlates directly to the width of the runway. Therefore, the correct answer reflects the established standard for a 45-meter runway width, which is set at 12 stripes.
