What colors represent an ALSF-2 approach lighting system?

The ALSF-2 (Approach Lighting System with Sequenced Flashing Lights) is a critical component of the instrument landing system that assists pilots during the approach phase of landing. The design of the system incorporates specific colors that standardize its visual depiction.

The correct representation for an ALSF-2 approach lighting system consists of red side row bars and white center lights. This configuration is crucial as the red side lights serve to delineate the lateral limits of the approach path, ensuring pilots are visually oriented and aware of the runway boundaries, especially under low visibility conditions. The white center lights provide visual guidance and help pilots align with the runway during the final approach.

Each color in this system has a specific function and follows aviation regulatory standards. Therefore, understanding the significance of the colors used in the ALSF-2 system is essential for safety and effective piloting during landing scenarios.
