.......... but to an outsider it seems that there is sometimes an important gap in the information trail from manufacturers' flight test expertise through their training departments to airline training departments to line pilots. Not just on stall behaviour; there are other examples where inherited wisdom was not passed on.
@ PJ2 I see your points, now tell me what will change and who will initiate the change? there are lots of saying like ..... my company is doing that and that .......i practice that and that.... and so on. Schouldnīt those necessary changes in training and qualification be regulated and monitored to a necessary standard?
