Which weather phenomenon is a significant concern for flight safety?

• A. Cloud cover
• B. Thermals
• C. Wind shear
• D. Clear skies

Answer: (C)

Wind shear is a significant concern for flight safety due to its potential to cause abrupt changes in wind speed and direction over a short distance. This phenomenon can occur at any altitude, but it is especially dangerous during takeoff and landing phases of flight when aircraft are flying at lower speeds and are more susceptible to sudden changes in performance. Wind shear can lead to difficulties in maintaining control of the aircraft, which can result in increased altitude loss, a stall, or a crash if not properly managed. Pilots must be aware of potential wind shear conditions, particularly in situations like approaching thunderstorms, over mountainous terrain, or during rapid changes in temperature or atmospheric pressure. While cloud cover, thermals, and clear skies can affect flying conditions, they do not pose the same level of immediate and severe risk to flight safety as wind shear, which can quickly lead to dangerous in-flight situations if encountered unexpectedly.
