What does the Low-Level Wind Shear Alert System (LLWAS) provide?

The Low-Level Wind Shear Alert System (LLWAS) is specifically designed to monitor wind conditions near the ground level, making option that describes it as providing wind data and software to detect changes in wind direction and/or speed the most suitable choice. This system is crucial for aviation safety, particularly for takeoff and landing phases, where sudden changes in wind speed or direction (known as wind shear) can pose significant hazards to aircraft.

The LLWAS accomplishes this by utilizing a network of sensors that provide real-time measurements of wind characteristics at various locations around the airport. When changes in wind conditions are detected, alerts can be issued to flight crews and air traffic control to inform them of potentially hazardous wind conditions.

Other options, such as those related to temperature readings, radar imagery, or landing gear failure warnings, do not fall within the purview of what LLWAS is designed to provide. LLWAS focuses exclusively on monitoring wind phenomena, making it an essential tool for enhancing situational awareness and safety in fluctuating weather conditions relevant to airport operations.
