APG you miss the point.
In any accident, loss of life or assets, are never down to a a single person, hence pilot error does not exist, was Three Mile Island 'operator error', was Herald of Free Enterprise 'ship's captain error' and when a surgeon kills a patient is that 'surgeon error'. We need to consider the wider framework within errors occur, hence I suggest you read some of James Reason's books. Pilot error is a thing of the past.
I should add Human Error is not UK GA speak, read the ICAO directives!
