For arriving IFR aircraft, when should runway edge lights be turned on?

• A. After the aircraft lands
• B. Before the aircraft begins final approach
• C. During taxiing
• D. Immediately after takeoff

Answer: (B)

Runway edge lights should be turned on before the aircraft begins its final approach to ensure the pilots have clear visual cues for the runway environment as they prepare to land. Illuminating these lights at this stage helps enhance the aircraft's visibility of the runway and provides important orientation during the approach phase, especially under low visibility conditions or at night. Turning on the lights before the final approach allows for optimal safety measures, as pilots can effectively assess the runway's position and dimensions while descending. This timing is crucial in aiding situational awareness, making it easier for the arriving aircraft to align correctly with the runway centerline. In contrast, turning on the lights after the aircraft lands would provide no benefit to the approach phase, and during taxiing, the focus shifts to different lighting requirements that address ground operations rather than the critical approach stage. Immediate illumination after takeoff does not serve the purpose for arriving aircraft, as they would be departing rather than approaching the runway.
