What colors represent an ALSF-2 approach lighting system?

The ALSF-2 approach lighting system is a critical component for guiding aircraft during the landing approach, especially in low visibility conditions. The system is designed to provide pilots with visual cues to help align with the runway. The correct representation of the ALSF-2 system's color scheme consists of red side row bars and white center lights.

Red side row bars are placed alongside the approach path to indicate the lateral limits of the safe approach area, deterring pilots from straying too far from the required trajectory. The white center lights are used to create a clear and visually recognizable approach path that assists pilots in their descent and alignment with the runway. This combination of colors ensures optimal visibility and guidance.

The other color schemes presented in the options do not reflect the standard designated use for an ALSF-2 lighting system, which is specifically recognized for its red and white color combination. This standardization is important for enhancing the safety and reliability of visual approach aids across different air traffic environments.
