What does a series of arrows painted on the approach end of the runway signify?

The presence of a series of arrows painted on the approach end of the runway indicates that the threshold has been displaced. This means the usable length of the runway has been shortened, moving the starting point of the runway further down. These arrows act as visual cues for pilots, guiding them to the new threshold location, which is important for their approach, landing distance calculations, and runway safety.

When approaching a runway with displaced thresholds, pilots need to be aware that they must touch down before the arrows and that the first part of the runway beyond the arrows is not available for landing purposes. Thus, understanding this visual indicator is crucial for pilots to ensure safe and efficient landings, especially in scenarios where the full length of the runway is not usable.
