Hi Doc....Call me a "bluff old cove" but all helo` pilots should know at what main rotor speed the old girl stops flying. The FRC`s and flight manual will have a section of limitations showing both power-on and power-off Max and Min Nr, and demonstrations of Nr droop/decay will "hopefully" have been given during training. As for Nr/Sec lost, again, I`m sure the Test Pilots could,if asked, produce a comprehensive table and DA/Airspeed graphs up the ying yang, and once a year I`d demonstrate my ability to read them. But if the engines go BANG, that levers going down, and just hear that Nr wind-up to MaxPwr-Off, plus a bit for the wife and kids in the flare.
