The aircraft knows the wind direction and speed, right? I'd be interested in knowing if Boeing has determined the aerodynamic loads on the airframe for a stationary aircraft on the ground according to wind direction and intensity; and then in turn feeds this info onto the AUM / CG calculator. My guess is this is not accounted for but it's just a guess.
