What is an important characteristic of wind shear?

Wind shear is characterized by sudden changes in wind speed and direction, which can have significant implications for aviation safety and performance. This phenomenon can occur at various altitudes and is especially critical during all phases of flight, including takeoff and landing. The rapid transition in wind conditions can lead to challenges in maintaining altitude and control of the aircraft, which is why pilots are trained to be aware of and manage wind shear conditions. Understanding this characteristic helps in recognizing potential hazards and preparing for how to respond effectively when encountering wind shear during flight.
