For fixed wing, one of my friends aims to make a steep turn and run through his own wake - like hitting a speed bump. He can do this time after time now, but does confess that it was long practice that led to this.
I was taught this during my PPL training and thought achieving hitting my own wake was a good indication of a level steep turn. However, someone then pointed out to me that the wake will be descending, so perhaps all I managed to achieve was to lose height at the same rate as my wake!
