What role do runway edge lights play?

Runway edge lights are crucial for enhancing the safety and operational efficiency of runways, particularly during low visibility conditions, such as nighttime or adverse weather. Their primary function is to mark the edges of the runway, providing visual guidance to pilots during takeoffs and landings. By delineating the boundaries of the runway, these lights help ensure that aircraft remain on the designated strip, reducing the risk of runway excursions or accidents.

The design of runway edge lights typically includes white or green lights, which create a clear and consistent visual reference for pilots approaching or departing from the runway. This is particularly important in maintaining spatial orientation and awareness, especially during critical phases of flight. Consequently, understanding the role of runway edge lights is vital for ensuring safe and efficient air traffic operations.
