Really. When I read that line in the WSJ story, I was flabbergasted. I guess we can hope that the journalist got it wrong and the regulators don't really think the answer to the problem is to accept that crews will be presented with contradictory indications and try to "ensure" that they respond appropriately.

Excellent conceptualization, phylosocopter: "When the automation loses situational awareness . . ."
