My biggest concern is the seperation of the boundary layer as the spoiler rises which can cause a great loss of lift resulting in excessive roll rate with obvious results. Dean
The whole purpose of a spoiler is to "spoil" the flow. So, if functional, the spoiler kills the lift on the wing that it is on (or at least the spoiled portion of that wing). The side effet is to increase the drag.
So, your question doesn't make sense... the spoiler's purpose is to
kill the lift by disrupting the flow. The increased drag on that side results in proverse yaw.
