As much as I hate to drag this out again, I beg to differ a bit here. If I understand this right, your saying that a plane unloads the same with a head wind as a tail wind and that the only way it will unload is in a dive? Am I missing something here?
That's dead right. Once a plane is in the air the wind has no effect (apart from turbulence).
You may get the impression that the engine is revving faster on a down-wind pass but that's down to the increased doppler shift created by the higher ground-speed.
The plane is still flying at exactly the same airspeed and the engine is doing the same RPMs, regardless of whether it's heading into the wind or downwind.
