At what altitudes can Wind Shear occur?

Wind shear can occur at all altitudes due to variations in wind speed and direction in different layers of the atmosphere. This phenomenon can be present during any phase of flight, not just during take-offs or landings, as it is influenced by various factors including terrain, weather conditions, and changes in temperature.

At lower altitudes, wind shear may be caused by the interaction with surfaces like mountains or buildings, or through atmospheric conditions such as thunderstorms. At higher altitudes, it can occur due to jet streams or transitions between layers of the atmosphere. Recognizing that wind shear can affect flight safety at all altitudes is crucial for pilots and drone operators, as it can lead to unexpected changes in control and performance of an aircraft.
