What is wind shear?

Wind shear refers to a change in wind speed or direction over a relatively short distance or time. This phenomenon is crucial for pilots to understand, as it can create challenging flight conditions. For instance, wind shear can occur during takeoff and landing phases when aircraft are particularly vulnerable to fluctuations in wind. Pilots must be aware of how this change can impact the aircraft’s performance and handling.

Understanding wind shear is vital for navigation and safety. It can manifest as a horizontal or vertical change, such as when an aircraft encounters different layers of air that are moving in varying directions or at different speeds, which can lead to turbulence and affect lift. Recognizing wind shear helps in making informed decisions regarding flight paths and approach methods, thus enhancing overall flying safety.
