Who may use direct-dial or LLWAS wind information for operational purposes?

• A. Towers equipped with AWOS
• B. Towers equipped with LLWAS
• C. Facilities with an NWS office
• D. AT Personnel

Answer: (B)

Access to direct-dial or LLWAS wind information is tied to having the LLWAS installed at the facility. LLWAS gathers wind data from multiple sensors around the airfield and analyzes it to detect low-level wind shear and other hazardous wind conditions, then provides real-time wind information and alerts for on-duty tower personnel to use in managing arrivals and departures. Towers that only have AWOS can show wind values, but they do not provide LLWAS-specific data or alerts. An NWS office handles forecasts and broader weather services, not LLWAS wind data for airport operations. So, the system is usable for operational decisions only at towers equipped with LLWAS.
