What is the purpose of airfield lighting?

The purpose of airfield lighting is primarily to guide pilots during crucial phases of flight such as takeoff, landing, and taxiing. This lighting system is designed to provide clear and effective visual cues that help pilots navigate the airfield safely, especially under low visibility conditions such as nighttime or inclement weather. By using various types of lights, including runway lights, taxiway lights, and approach lights, airfield lighting ensures that pilots can identify the correct paths to follow, which is vital for maintaining safety and preventing accidents on the airfield.

While there are other considerations for airfield lighting, such as maintenance illumination or marking restricted areas, the primary and most critical function relates to assisting pilots with their operational needs during landing and takeoff.
