"How on earth does one assess "monitoring?""
By injecting faults onto the displays and noting the time it takes for a pilot to react in the correct manner?
A series of trials on new copilots at one operation found that none detected an oil pressure gauge sitting at zero during a half hour cruise segment on autopilot. Hard to believe maybe, but it seemed there was a reliance on the central warning panel to flash the "master caution" and "oil pressure low" segment.
