WebThe 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). WebA positive v wind is from the south, and a negative v wind is from the north. If we have the wind speed and wind direction, we can obtain the component vector winds, u and v, as follows: u = ws * cos(θ) v = ws * … argannot database
