Henry – “It's a training dept. duty to teach, details and update the single items meanings…”
I would agree, but taking care not to devolve personal responsibility for understanding, to someone else’s duty, e.g. are the details and updates taken from a single company reference, or is there latitude for individual instructor’s interpretation – one of many human factors problems in operations.
Nor must we forget that the decision at the end of an SOP – the judgement of risk, reasons, and ‘certainty’, remains the responsibility of the Captain. Thus it is in everyone’s interest to think through the issues well in advance of a potential RTO situation.
