Which lights provide guidance for the alignment of an aircraft on the runway?

Runway centerline lights play a crucial role in guiding the aircraft's alignment on the runway during takeoff and landing phases. These lights are typically embedded within the runway surface and illuminate along the centerline to provide pilots with a clear visual reference of where the aircraft should be positioned as it approaches the runway. The lights are spaced evenly and may change color depending on the proximity to the runway threshold. This feature helps ensure that pilots maintain proper alignment, especially during low visibility conditions or at night, enhancing safety and precision during critical phases of flight.

Other types of lights mentioned serve different purposes. For instance, runway edge lights are designed to define the edges of the runway, while runway end lights indicate the departure point of the runway. Threshold lights mark the beginning of the usable runway but do not specifically guide alignment in the manner that centerline lights do. Understanding the specific function of each type of lighting is essential for effective aircraft operation and navigation on the ground.
