What are the last 1,000 feet of runway centerline lights colored?

The last 1,000 feet of runway centerline lights are colored red. This specific color is used as a visual cue for pilots to inform them they are approaching the end of the usable runway, creating a critical visual reference during landing and takeoff.

The color red in this context signals caution and prompts pilots to assess their landing or takeoff trajectories. It's a standardized practice within airport operations to help ensure safety and effectiveness during flight operations. This use of color coding is a crucial part of aviation safety management, helping to prevent runway overruns and enhance situational awareness for pilots.

In contrast, other colors like white and green serve different purposes in the lighting system of airports. White lights generally indicate the middle sections of runways, while green lights are typically associated with taxiway indications. Thus, the distinction in colors is vital for pilots operating within the airport environment.
