Good replies!
I think it prudent to remain a little wary of simulators as the ultimate "gospel truth" for this type of failure because of the way they are programmed.
A manufacturer cannot test the ultimate aerodynamic behaviour of his aircraft's response following tail rotor malfunctions / failures in any great depth, for obvious reasons. A "best estimate" response is usually programmed into the software for cases like this, which are known as "off model" situations.
What sims are really great for is to teach understanding of the different types of TR malfunction and developing a strategy to deal with them.
