What is the function of high and low intensity approach lights?

• A. To provide runway distance information
• B. To assist in aircraft navigation and alignment
• C. To signal the end of the runway
• D. To guide ground vehicles

Answer: (B)

High and low intensity approach lights are primarily designed to assist aircraft during the landing phase by enhancing navigation and alignment with the runway. These lights are strategically placed in a pattern to help pilots determine their position and approach path as they descend towards the runway. The high intensity lights are particularly useful in poor visibility conditions, providing a clear visual reference that aids in aligning the aircraft with the runway centerline. This guidance not only improves safety during the critical phases of landing but also enhances situational awareness for the pilots, allowing them to make necessary adjustments to their approach angle and descent rate. Utilizing these lights effectively ensures that pilots can navigate even under challenging weather conditions, thus playing a crucial role in the overall safety and efficiency of air travel.
