WebFormula. The crosswind component is equal to the speed (V) of the wind multiplied by the sine of the angular difference (XWC = V × Sineθ). Therefore, in the example given above (Rwy 21 – W/ V 240/20) the angular difference is 30 degrees, and the sine of 30 degrees is 0.5. This means that half the wind strength is crosswind (20 × 0.5 = 10).
