Sunnyjohn,
Not true. Human frailty was discussed in condiderable depth in the MCC course I ran up to about three years ago. The pressures that might bear on a pilots performance such as financial, domestic, work or union related and many others were raised either by myself or my students. It was emphasised that a PNF should always be alert to the posibility of these factors affecting either them or their PF. It actually formed a significant element in my human factors teaching. Don't know how others did/do it, but I am sure it is fully covered. May be different in other parts of the world of course.
