touchdown-zone light

Touchdown-zone lighting is a component of airport lighting systems designed to aid aircraft during landings, particularly in low-visibility conditions. These lights are embedded flush with the runway pavement and illuminate the first 900 meters (3,000 feet) from the runway threshold. Their purpose is to provide crucial guidance to pilots during the final moments before touchdown, enhancing safety when visibility is reduced. This system is part of the broader airfield lighting infrastructure that includes runway threshold lights, edge lights, centerline lights, and end-of-runway lights, all working together to guide aircraft safely on the ground and during approaches and takeoffs.1
