What does the non-landing portion of a runway indicate?

The non-landing portion of a runway refers to the area that is designated for specific uses other than landing, typically starting from the displaced threshold. This section is marked with white arrows that indicate to pilots that these areas are not to be used for landing operations. By defining this area, the airport ensures safety and efficient use of the runway, providing clear guidance to pilots about where landing maneuvers should commence.

Understanding this concept is crucial for pilots as it delineates where they can safely begin their landing approach, thus helping to avoid potential accidents and maintain the orderly flow of air traffic. The use of arrows is a uniform way to communicate this important information visually.
