What is the primary function of illuminated marshalling wands used during nighttime operations?

The primary function of illuminated marshalling wands during nighttime operations is to provide clear and unambiguous visual signals to the aircraft pilots and ground crew, ensuring safe and accurate aircraft movement in low-light conditions. During daylight, marshalling signals are easily visible. However, at night or in conditions with poor visibility, standard hand signals become difficult or impossible to see from the cockpit or by other ground personnel. Illuminated wands, typically using LED lights, emit a bright, focused light that makes the marshaller's signals highly visible. This allows the pilots to accurately interpret instructions regarding taxiing, turning, stopping, and other maneuvers. The use of illuminated wands also improves safety by enhancing the overall awareness of ground crew members, reducing the risk of collisions or other ground incidents. The consistent and standardized visual communication provided by these wands is crucial for maintaining safe and efficient ground operations in challenging visibility conditions.
