The report makes some interesting human factors observations on pilots faced with a transition from VFR to IMC.
‘a. When under stress, people tend to place a greater emphasis on positive
outcomes when making decisions.
b. When conditions deteriorate gradually, cues suggesting that a course of
action be abandoned often fail to change that course.
This indicates that, if intending to remain in VMC, it is better to anticipate the
need to avoid the boundary between VMC and IMC than to fly towards it and,
perhaps inadvertently, across it.’
