I'm curious what people's understanding of dead mans curve is, and how you might apply a HV chart in an operational context.
From the eye witness account the helicopter was out of control, and the tail boom was chopped off before it hit the ground. Engine failure is still a possibility...the eye witness description might fit a low RRPM situation during an auto-rotational descent.
