If runway centerline lights are installed on a runway with a length of 1800 m or more, what is the color in the segment from 300 m to the runway end?

In runway lighting systems, specifically regarding runway centerline lights, the color coding plays a crucial role in providing visual information to pilots during approach and landing. For runways that are 1800 meters or longer, the lighting configuration helps indicate the distance remaining to the runway end, using color changes to aid pilots in their decisions.

From the 900 meters mark to 300 meters, the lights display an alternating pattern of red and white. This signaling informs pilots that they are approaching the critical point of the runway, combining visibility with a clear indication of distance remaining.

Once the aircraft is within the last 300 meters of the runway, the lights turn red. This is particularly significant as it indicates that the aircraft is now very close to the end of the runway and that careful attention is required to ensure a safe landing. The change to solid red from this point on serves as a warning, prompting pilots to be aware that they are nearing the end of the usable runway space.

This configuration is standard for lengthy runways, ensuring that pilots have the necessary visual cues to manage their descent and landing safely. The correct lighting not only enhances safety but also aids in operational efficiency by guiding pilots effectively during critical phases of flight.
