What is a direct consequence of wind shear on flight?

• A. Sudden changes in airspeed and altitude.
• B. Improved fuel efficiency.
• C. Reduced turbulence.
• D. No effect.

Answer: (A)

Wind shear means the wind speed or direction changes abruptly over a short distance. That rapid change directly affects the airplane’s airspeed and vertical motion, so you can experience sudden climbs or descents as the aircraft encounters the shifting air. This is why the direct consequence is sudden changes in airspeed and altitude. Wind shear does not improve fuel efficiency, it often increases the challenge by adding turbulence and requiring quick pilot corrective actions, and it certainly has an effect on the flight.
