PBL:
Using my prior analogy and your summarization, Risk Control is keeping the gasoline away, IA is throwing the lighter in the pocket, beeing the 2nd easier to achieve.
The general knowledge of factors originating various accidents is a source for the pilot, to help him identify risks, which is what I think is more critical in Risk Control. Adherence to the SOP's is also a quite "passive" but very important way of contributing to RC, as it uses organizational knowledge systemathized to keep risk away. I also believe the Theory of Chaos is a good way of interpreting flight safety, and managing to mantain a low level of chaos is a good way of mantaining safe flight. Much of this has to do with RC, I think. This may be an old theory, but it seems to work allright to me.
