What is the purpose of wind shear detection systems?

Wind shear detection systems are specifically designed to identify rapid changes in wind speed and direction. These changes can occur at various altitudes, particularly during takeoff and landing phases, and are critical for flight safety. Wind shear can lead to changes in airspeed and aircraft performance, potentially resulting in a loss of control if not detected and managed appropriately. By alerting pilots to these hazardous conditions, wind shear detection systems provide essential information that allows for more effective decision-making and enhanced safety.

The other options do not accurately reflect the primary role of wind shear detection systems. Monitoring fuel levels focuses on fuel management during flight, while measuring atmospheric pressure relates to weather systems rather than wind shear identification. Assisting with navigation concerns directional guidance rather than detecting disruptive wind patterns. Hence, the selection of the option related to wind speed and direction is aligned with the primary function of wind shear detection systems.
