Multiple Unrelated systems failures during simulator training
The vast majority of pilots who are subject to scheduled simulator checks have seen the situation where the check pilot introduces systems failures that are often unrelated. Example: Tyre burst on take off followed by engine failure caused by FOD and maybe asymmetric flap caused by tyre debris. The imagination of some check captains knows no bounds and events like these are sometimes known as double jeopardy failures. Even the aces of the base have trouble coping with this sort of "training."
That said, it is informative to ponder CASA Civil Aviation Advisory Publication (CAAP) 5-23-2 (0) under the chapter Multi-Engine Aeroplane Operations and Training - sub heading Generic Range of Variables. Briefly, this gives CASA's thoughts on flight training and includes the following line of advice:
"Assessment should not involve simulation of more than one emergency at a time".
There are obvious good grounds for that statement based on long established principles of teaching. Yet, many pilots have walked unsteadily from a head banging simulator session convinced they will never make the grade because of a perceived inability to hack multiple emergencies, when in fact it is the instructor that is pushing the bounds of fair and intelligent instruction.
