Re this
post .. sideline philosophical consideration ..
As each crew ultimately fails at a different level, I .. have some information upon which to help inform who needs work on what....
Likewise, the crews may .. be aware on their own of some limits or holes in their knowledge of systems that they were not previously aware of.
My original comment was directed at routine sim work and I stand by the philosophy for routine (training value emphasis with a lower case "c" checking strategy) sim work.
In the specific circumstances you cite, I am with you .. indeed, I would be in the line to participate for the reason you consider .. just where is my personal brick wall ? The underlying research value for training strategies is valid .. but the participants must be willing and not at jeopardy.
Perhaps we should have a beer or ten to debate the pros and cons ?
