Another obvious difference with military training was understanding that faults and failures often led to other faults and failures. On a check ride at low level, one of the Squadron QHIs would casually say "you've just taken a round to the Hydraulic pack", then take out the Hydraulics, after letting you wrestle with the controls for a bit and do the Gazelle straight-leg pedal lock, he would say "where do you think all that leaking fluid is going? I reckon it's going down the engine intake - Practice engine failure - Go". So now it's a zoom climb and then try to find a hole in the woods to put it down, all in manual reversion. Others argued that it was extremely unlikely and therefore unrealistic, but it certainly taught you to understand that bad news is never far away in a helicopter.
