Steep turns in the normal course of civil operations would be an emergency manoeuver. A turn to avoid hitting a bird/a plane/Superman.Can't see any other reason to do it,except to show off to the crowd/girlfriend/peers. Further, under the right conditions over the desert mountains of the US,on a hot summer day, everything can come together like a perfect storm where a gust of wind in cruise can set off a jack stall.The onset is unmistakable and needs a contolled reaction.Not a big deal once you have a few hours in the EC models.A good training module should cover this and take the mystery away.For many years, pilots were told/trained to believe that the AS350 hydraulics were an accident waiting to happen,that a hydraulic failure could kill you etc.Nothing can be further from the truth. Like everything else (LTE anyone?) good training,increased awareness and a good knowledge of the systems involved would take away the aura of death from these aircraft.
And ,no, I am not being an apologist,merely a realist.
