What is the distance between NATO T lights?

The correct distance between NATO T lights is 10 meters. This spacing is essential to ensure that the lights are positioned effectively for visual reference and signaling during flight operations. Proper spacing allows helicopter pilots to easily identify the landing zone from the air, enhancing safety and the overall efficiency of the landing process. The 10-meter spacing facilitates clear visibility and minimizes the risk of confusion, especially in varying visibility conditions or during nighttime operations. By adhering to this standard, personnel can ensure that the HLZ is properly marked and meets the necessary criteria for effective helicopter landings.
