No, but intended to disprove theory that it is FBW that allows you to fly closer to the line - since it doesn't have it.
I don't recall in the 447 thread, (either one) where CC issues were completely rejected?
I do recall posts that actually calculated the margins based on the reported weight, fuel, height, flight-time etc., and came up with reasonable numbers.
That does depend on what you define as a reasonable margin and what is CC, and what is reasonable in a normal cruise may not be good in a CB with unreliable IAS. On the other hand, both CBs and AS problems can and have killed, without needing help from CC.
Only the recorders will tell us (and sadly I don't think they'll be found anytime soon).
