How is runway lighting significant in airfield operations?

Runway lighting plays a crucial role in enhancing the safety and efficiency of airfield operations, primarily by improving visibility for pilots during takeoffs and landings. Properly illuminated runways allow pilots to better judge their approach path and landing point, particularly in low-light conditions or adverse weather situations. The design and configuration of runway lighting, including edge lights, threshold lights, and runway end identifiers, help create a clear visual reference that assists pilots in aligning safely with the runway during critical phases of flight.

By improving visibility, runway lighting contributes to reducing the risk of accidents, ensures the proper execution of approach procedures, and helps pilots in maintaining situational awareness. This is essential for optimizing performance and ensuring safety in what can be some of the most challenging flying conditions. Conversely, the other options involve aspects of airport operations that do not primarily focus on the direct visibility aspect provided by runway lighting.
