Which watch is associated with notifying airfield leadership that the RVR system requires the runway lights to be left on during airfield closure hours?

• A. ATC directives
• B. EUs with AMOS systems
• C. Cooperative Weather Watch (CWW)
• D. Observing Aids for Visibility

Answer: (C)

Cooperative Weather Watch is the function that monitors weather-related conditions affecting flight operations, including runway visual range and visibility, and communicates those conditions to airfield leadership so decisions about runway lighting during closure hours can be made. When RVR readings indicate reduced visibility, this watch alerts the leadership that the runway lights should remain on to maintain safe visibility for any ongoing maintenance, inspections, or potential returns to operations. ATC directives govern traffic control rather than internal weather- and lighting-related decisions. EUs with AMOS systems and Observing Aids for Visibility are tools or units involved in observation, not the dedicated watch responsible for notifying leadership about RVR-related lighting needs.
