Technology can make idiots of their operators.....when you over
spec the GUI etc.....and automate the soldier into airheads.
IMO you need to leave some room for the operators to not totally
trust the system such that 30% of his/her brain is running
contingency scenarios.....
So if he/she is tired......then he can run with more safety
margins.
But when system has an alarm and worst, an automatic fallback
condition for ALL SITUATION ALL THE TIME......he/she tends to take
it easy.
When things go wrong, blame it on system malfunction!
I have seen a system in Taiwan during April (very hot), when the
transistors threshold driving LEDs start going haywire and alarms
keep beeping off everywhere.
Wah, good training for all! Of course today everything is on BARCO
screens and you have built-in simulators to wake you up. Still not
quite the same.
