GS = TAS \pm W

Ground speed is true airspeed adjusted for the headwind/tailwind component.

HW = W\cos\theta,\; XW = W\sin\theta

Resolve wind into headwind and crosswind components relative to runway/track.

XW = V_w\sin\theta

Crosswind component determines whether landing is within aircraft limits.

X = V\sin\theta

Sideways wind component during landing.

H = V\cos\theta

Wind component along the runway.

P = \frac{1}{2}\rho A v^3 C_p

Power extracted from wind by a turbine.

C_{p,max} = 0.593

Maximum fraction of wind energy a turbine can capture.
