Thank you TC,
We are not to far apart on this.
Every operator I know reccognizes and respects the performance envelope put out there by the test pilots and engineers. However, staying out of the avoid curve is just not a reality to our industry. Like you said, we do our best to limit the time there, limit weight to increase options in the event something goes wrong, and we all do far more than minimum required maintenance.
I called the avoid curve a disclaimer becuase that is exactly what it is. The manufacturer cannot assure a safe outcome if you are within it during an engine failure. If their objective was to keep you out of it they would have put it in the limitations section of the RFM. They know, as well as we do, that inside the avoid curve is where these machines (particularly utility machines) were ment to operate and they woiuldn't sell many if that were a limitation.
We are getting off topic
