I'm very concerned about where this thread is leading. There is no manoeuvre that will ensure terrain avoidance as described and to believe that there is is dangerous fantasie. Even if any terrain was to be avoided with an extreme manoeuvre, a loss of spacial awareness and control is sure to follow.
The only way to avoid terrain with certainty is to avoid it with a wide berth or by flying above it at a minimum safe altitude, whatever the flight conditions.
This, all of it.
