Runway edge lights

Runway edge light is a very important part of airport navigation lighting system. The following is detailed introduction about runway edge lights.

Definition and Function of runway edge lights

Runway edge lights are installed on both sides of the runway. Their main function is to mark the boundaries of the runway and ensure that aircraft can accurately recognize the location and range of the runway during night flights or in low visibility. These lights are usually designed to be lightweight and easy to fold to avoid damage during takeoff or landing.

Characteristics of runway edge lights

Color and brightness: Runway edge lights are generally white lights which light constantly, but when the runway threshold is moved inward, the lights from the runway end to the moved inward runway threshold will be red in the approach direction. Within 600 meters of the end of the runway (if the runway length is less than 1,800 meters, the length of the runway edge lights that emit yellow light should be 1/3 of the runway length), the runway edge lights facing the middle of the runway are yellow to warn pilots to pay attention to the end of the runway.

Arrangement and Installation of runway edge lights

Position: Runway edge lights are evenly distributed along the edges of both sides of the runway to ensure that pilots can clearly see the runway boundary. Runway edge lights are installed along the entire length of the runway on the straight lines on both sides of the runway that are equidistant and parallel to the runway central line, or installed no more than 3 meters outside the runway edge.

Spacing: The longitudinal spacing between lamps is set according to specific needs to make sure the continuity of the runway boundary.

Importance of runway edge lights

Runway edge lights play a vital role in the airport navigation lighting system. They not only provide pilots with clear runway boundary identification, but also improve the safety of flying at night or in low visibility conditions, and reduce the flight accidents. When the runway edge lights fail or are damaged, they should be repaired or replaced in time to ensure the normal operation of the airport and flight safety.

Technical specifications and design features of runway edge lights

Runway edge lights usually use LED light sources, which have the characteristics of high luminous efficiency, low power consumption, good uniformity and easy installation. The lighting system is reasonably designed to ensure clear visual indication in all weather conditions.

In summary, runway edge lights are an indispensable part of the airport navigation lighting system. They tell pilots with accurate runway boundary identification by emitting constant and clear light, thereby improving flight safety and reliability.
