Which hazard best describes wind shear and microbursts during takeoff or landing?

• A. Loss of airspeed or control.
• B. Inability to read instruments.
• C. Fuel exhaustion.
• D. Structural damage due to pressurization.

Answer: (A)

Wind shear and microbursts involve abrupt changes in wind speed and direction over a short distance, which can slam an airplane with a sudden loss of airspeed and lift, especially during takeoff or landing when speed and angle of attack are critical. This abrupt change can lead to a rapid decrease in performance and, if not corrected promptly, a loss of control near the ground. Microbursts can also produce powerful downdrafts that push the aircraft downward, compounding the risk during approach or departure. That combination—sudden airspeed loss and potential control difficulty—is the central hazard these phenomena pose in the high-stakes phases of flight. Inability to read instruments, fuel exhaustion, or structural damage from pressurization are unrelated to the immediate aerodynamic danger presented by wind shear and microbursts, which is why the best description is a loss of airspeed or control.
