When utilizing the NATO T, how many lights are used to mark the touchdown point?

When marking the touchdown point using the NATO T, five lights are used. This configuration is designed to provide a clear visual reference for helicopters during landing operations, ensuring that pilots can easily identify the designated landing zone in various conditions. The five lights create a distinct shape that aligns with the NATO standardization, enhancing safety and operational efficiency. The specific arrangement and number of lights help to avoid confusion and improve the precision of landings, particularly in low visibility scenarios.
