What does the wind-shear forecast WS005/27050KT indicate in terms of the height of the wind shear?

• A. 50 ft AGL
• B. 5,000 ft AGL
• C. 500 ft AGL
• D. 50,000 ft AGL

Answer: (C)

WS indicates a wind-shear forecast, and the height is given in hundreds of feet above ground level. The value 005 means 005 × 100 = 500 feet AGL. The rest of the data (27050KT) describes the wind expected at that layer (from 270 degrees at 50 knots). So the wind shear is forecast at 500 ft AGL, which is why the correct choice is 500 ft AGL.
