Hmmm....maybe not!
Miserlou,What u are essentially trying to say is that you would'nt EVER get ANY wind indications on ground.I beg to disagree to that.I have had wind velocities on t/o runs.Say u are taking off into a 100 kt headwind(hypothetically),would i get a wind speed or not.And at what IAS would that be??And say my VR is 150kts,i obviously would lift off at 50 kts G/S right?How do u explain that. And say i'm landing into the same headwind...?? However i fully agree with your explanation of the mechanics of the data input.ANY more input is welcome.
