RCL stands for which term?

• A. Runway Centerline Elevation
• B. Runway Centerline Length
• C. Runway Centerline Elevation Datum
• D. Runway Centerline Axis

Answer: (A)

Runway Centerline Elevation is the vertical position of the runway’s centerline above mean sea level. This value provides a reference for surveying, design, drainage, and obstacle clearance calculations, and it’s a standard data element used on airport charts and records. It’s not the length of the centerline, the axis orientation, or a reference datum—those describe distance, direction, or a different kind of reference surface. So the term that best matches the acronym RCL is Runway Centerline Elevation.
