With respect, and it may be just an error in understanding, your reference to the crew being "overwhelmed" is precisely the problem: trained crew don't get overwhelmed, it's in the T/C's. Seriously, if the capability exists to alert to a potentially dangerous condition, especially when the crew should be sensitive to it ( "Test" ), and it isn't forthcoming, that is a 100 percent FAIL in the machine/man interface, No?
