Thanks Sunfish
That's a good one. The section that caught my eye was this;
"A pilot may make a series of good decisions, but that is no automatic protection against a subsequent poor decision putting the safety of the flight at risk. The flight is only ever as safe as the pilot’s last decision.
A parallel can be drawn between the importance of a pilot, at an individual or 'micro' level, being continually mindful of the situation they face and similar concepts that have been advocated at a systems safety or 'macro' level... A guiding tenet of this approach is that 'the price of safety is eternal vigilance', the idea that no system can guarantee safety for once and for all.
The application of this approach to the level of the individual pilot would include aspects such as the importance of a pilot not flying to the limit of their abilities, and of not letting past success breed complacency."
