What components are part of the MALSR lighting system?

The MALSR (Medium Intensity Approach Lighting System with Runway Alignment Indicator Lights) is a critical component used in airport lighting to enhance visibility for pilots during approach and landing phases. The system is designed to provide clear visual cues and is composed of several key components that work together to ensure safety.

The correct answer includes threshold lamps, steady burning light bars, and flashers, all of which play specific roles in the approach lighting system.

Threshold lamps are positioned at the start of the runway and serve to indicate the landing threshold for pilots approaching the runway. They provide a clear visual reference point, particularly under low visibility conditions.

Steady burning light bars contribute to the intensity and clarity of the visual cues by providing uniform lighting along the approach path, enhancing pilots' ability to determine their position relative to the runway.

Flashers are used to capture attention, especially in critical landing moments. The alternating lights serve to alert pilots and help maintain their focus on the landing area, providing a dynamic visual signal that contrasts with the steady illumination from other components.

Together, these components create a comprehensive lighting solution that significantly improves both the safety and efficiency of aircraft landing operations, making the correct answer the comprehensive description of the MALSR lighting system components.
