CONTROL-EFFECTIVENESS APPROXIMATION rudder (degrees) wing has NON-FLUSH rivets, control surfaces are corrugated, and there are control-surface gaps roll spoiler (degrees) wing has FLUSH rivets, smooth control surfaces, but some control-surface gaps drag rudder (degrees) wing has FLUSH rivets, smooth control surfaces, and no control-surface gap. speedbrake (degrees)
