What is the function of pilot-controlled lighting?

Pilot-controlled lighting primarily serves to enhance runway visibility, especially during low-light conditions or adverse weather. This system allows pilots to activate the runway or taxiway lights through radio frequency transmissions, ensuring that they have adequate illumination when approaching or departing from an airport. This is particularly crucial in facilitating safe takeoffs and landings in environments where natural light is insufficient.

While managing air traffic control lights, guiding pilots during taxiing, and signaling emergency landings may all be related to airport operations in some way, they do not accurately represent the specific functionality of pilot-controlled lighting. This system is designed explicitly to improve visibility for pilots, making it essential for safety in landing and takeoff scenarios.
