TeT - in the example accident - he is already running short of power, then he sets 20 degrees nose up and rolls to 43 degrees!!! where is the vertical component of rotor thrust coming from to balance the aircraft weight? No wonder he descends quickly - then he compounds it by stuffing the nose down to 16 degrees!!
Not VRS in any way shape or form just mishandling and poor awareness.
Nick, I have always found that a fixed power transition from the hover in still air gives a descent just before ETL is achieved as the rotor tries to battle its way through the tip vortices to clear air - are you saying this doesn't happen?
