Runway Centre Line markings consist of broken white lines spaced approximately how far apart?

• A. 60 metres
• B. 30 feet
• C. 15 metres
• D. 30 metres

Answer: (D)

Runway Centre Line markings are designed to give pilots a clear, repeatable visual cue to stay aligned with the runway center. The broken white line is made up of segments spaced at regular intervals along the runway, and those intervals are approximately 30 metres apart. This spacing helps maintain a consistent reference as you approach, land, or roll out, so you can judge your position relative to the centerline from a distance and at high speed. The other options don’t reflect the standard visual cue used for this marking—the 30-metre spacing is the established pattern that keeps the centerline easily visible and interpretable across lighting and runway conditions.
