What is a key hazard of wind shear for aircraft?

• A. It can cause significant changes in airspeed and attitude, challenging control.
• B. It only occurs at high altitude.
• C. It causes gusts but not hazards.
• D. It always improves climb performance.

Answer: (C)

Wind shear is a rapid change in wind speed or direction over a short distance relative to the aircraft’s path. This can cause abrupt changes in airspeed and flight attitude, making it hard to maintain stable control. The danger is greatest during low-altitude phases like takeoff and landing, when the aircraft is at lower speeds and less forgiving of sudden gusts or shifts. It isn’t confined to high altitudes; wind shear can occur near the ground and in other parts of the flight envelope due to convective activity, jet streams, or weather fronts. It also isn’t just gusts without hazards, and it certainly doesn’t always improve climb performance—the changes can lead to loss of airspeed, uncommanded pitch or roll, or even stall if not managed promptly. So the key hazard is those abrupt changes in airspeed and attitude that challenge the pilot’s ability to control the aircraft.
