What is the phraseology used for wind shear at locations equipped with LLWAS?

• A. "Low level wind shear advisory"
• B. "Wind shear detected at runway"
• C. "Wind shear alert: airport wind at velocity"
• D. "Pilot caution: wind shear imminent"

Answer: (C)

The phraseology "Wind shear alert: airport wind at velocity" is used when wind shear is detected at locations equipped with a Low Level Wind Shear Alert System (LLWAS). This system continuously monitors wind conditions at low altitudes and provides crucial information to pilots about potentially hazardous wind shear situations. The inclusion of "alert" indicates that there is an immediate concern for safety due to sudden changes in wind speed or direction, which can significantly affect aircraft performance during critical phases of flight, such as takeoff and landing. The phrase articulates both the nature of the warning and the specific wind conditions at the airport, allowing pilots to make informed decisions regarding their approach or landing. The focus on providing a clear and direct wind speed measurement helps in situational understanding and is essential for maintaining safety in the vicinity of the airport.
