Dear Les,

This is probably true and, if I understand well, has been used by 
Airbus since the A320's gust alleviation system.
Back in circa 1989, I attended a presentation by someone from British 
Aerospace explaning how the gust alleviation system reduces stress on 
the overall structure. This stress reduction enables structural weight 
savings. The counterpart is that this also slightly reduces structural 
rigidity and therefore induces a small increase in metal fatigue in some 
areas. The control system includes a gust profile predictor.
Search "gust alleviation system".

Les: Please post to SystemSafety at Bielefeld only or more fatigue and 
a general breakdown shall ensue.
