What happens on the LLWAS display when wind shear is detected by a remote station?

• A. It shows STATION ERROR
• B. The wind direction indicator rotates
• C. The entire LLWAS panel cycles colors
• D. The corresponding runway arrival/departure row will flash

Answer: (D)

LLWAS flags wind-shear events by drawing attention to the specific runway row that corresponds to the station where the shear was detected. When a remote station detects wind shear, the associated arrival/departure row on the LLWAS display will flash to alert the controller that this particular runway’s approach path is affected. This focused indication helps you quickly assess and respond—issuing cautions or adjusting operations as needed. Other indicators, like a station error message or a panel-wide color change, would signal different conditions (such as a fault or system-wide status) rather than a localized wind-shear event.
