Gordy, I think low rotor rpm demonstration is vital to students, understanding the phenomena, but, operating outside of rotor limitations?
Good point, however, are we not operating outside of rotor RPM limits when conducting autos and hover autos? Also getting SWP for demonstration, and back in the day doing Low G maneuvers, (although no longer permitted I hear) were operating outside of a "normal" flight envelope.
The demonstration I conducted was considered a demonstration of low rpm recovery and tail rotor authority and control.
