What can rapidly changing wind directions near the ground lead to during takeoff or landing?

• A. Stable flight conditions
• B. Increased fuel efficiency
• C. Loss of control
• D. Improved visibility

Answer: (C)

Rapidly changing wind directions near the ground can lead to a loss of control during takeoff or landing due to the impact of wind shear. Wind shear refers to the sudden change in wind speed or direction over a short distance, affecting the aircraft's handling characteristics. When an aircraft encounters wind shear, it may experience unexpected changes in lift, which can be critical during these low-altitude phases of flight. This unpredictability can cause difficulties in maintaining the desired flight path, potentially leading to adverse situations such as difficulty with climb performance or abrupt descent rates. In contrast, factors like stable flight conditions, increased fuel efficiency, or improved visibility are not generally associated with rapidly changing wind directions. Instead, they denote a more consistent and favorable operational environment that supports safe and effective flying conditions. Consistency in wind direction and speed contributes to smooth maneuvers during takeoff and landing, thus distinctly highlighting why option C is the pertinent answer in this scenario.
