Web6.2.3 Wind Axis System. The wind axis system is similar to the stability axis system except it is rotated about the \(z_s\)-axis through the angle of sideslip, \(\beta\).. The term “wind” … Over the time interval to be averaged across, n measurements of wind direction (θ) will be made and two totals are accumulated without storage of the n individual values. At the end of the interval the calculations are as follows: with the average values of sin θ and cos θ defined as Then the average wind direction is given via the four-quadrant arctan(x,y) function as From twenty different functions for σθ using variables obtained in a single-pass of the wind direc…
