Pete,
Our procedure was developed by check and training in the simulator at West Palm. On my event rig personel said the tail rotor missed by about 20 feet. In the A model days it was just a case of get into the hover and fall off the edge. It was left to pilot judgement as to how to handle the situation. It was not until we had been operating multi's for quite some time that consideration was given to the "what if" and the stated procedure developed.
