"So I am talking about risk assessment where the combinations of known limitations and factors (that in themselves may be acceptable) are
examined to see whether there is any factor that, when interacting with one or more other factors, takes the overall risk factor above an
acceptable level.
Of course there will always be the 'unknown' risks, but if you have a sufficient margin of comfort with all the others, then you are better able to
deal with a sudden emergency than when you are right up against the limit of safety and then something unforeseen occurs ..."
The design regulation JAR 25.1309 and its advisory material do call for assessing the combinations of risks and of course the subsequent limitations to flight in the maintenance and operating manuals do take this into account. My risk management comments had more to do with continued airworthiness and the expected variations among the contributing causes.
I don't believe that there is a lack of process.
