Where are Runway Edge Lights located?

Runway edge lights are indeed positioned along the full length of the runway. This continuous illumination is crucial for pilots during takeoff and landing, particularly in low visibility conditions. The lights help to define the edges of the runway, providing visual guidance to pilots as they approach and depart. The placement of these lights ensures that pilots can accurately determine the boundaries of the runway throughout its entire length, enhancing safety and operational awareness.

Other placement options, such as midpoints, only at takeoff and landing zones, or solely at the threshold and end, do not provide the comprehensive visual guidance that the full length of runway edge lights does. By lighting the entirety of the runway's perimeter, these lights maintain a consistent reference point, which is vital for successful aircraft operations.
