How many threshold stripes does a runway 23 m wide have?

The correct answer is based on the specifications outlined in international aviation standards regarding runway markings. A runway that is 23 meters wide falls into a specific category that requires a certain number of threshold stripes.

For runways that are 20 meters wide or more, regulations typically dictate that there should be six threshold stripes. This is designed to enhance visibility for pilots during landing approaches and to clearly denote the beginning of the runway that is available for landing.

Thus, the number of threshold stripes is determined by the width of the runway, and for a 23-meter wide runway, the standard is indeed six stripes, which provides proper guidance and aids in safe aircraft operations.
