What are the lights at the end of the runway in line with the centerline?

The lights at the end of the runway that are aligned with the centerline serve an important role in providing visual guidance to pilots during landing and takeoff. The configuration mentioned, featuring red and white lights, indicates that the runway is in a position to provide clear visibility and safety.

Specifically, the red and white lighting system signifies that the aircraft is approaching the runway safely. When the aircraft is a certain distance from the runway threshold, it will see a combination of these colors, which provides reassurance regarding the distance remaining to the runway.

Understanding this light system is crucial for pilots, especially during periods of low visibility or at night when visual cues are limited. The reason this is the correct answer lies in the operational standards for runway lighting that prioritize safety and clarity for approaching aircraft.
