What percentage is designated as the NR Power-Off Maximum?

• A. 100%
• B. 95%
• C. 110%
• D. 105%

Answer: (C)

The NR Power-Off Maximum is designated as 110%. This percentage indicates the maximum rotor speed that can be sustained during a power-off condition, ensuring the rotor system operates safely and efficiently during descending flight or autorotation maneuvers. A rotor speed of 110% allows for optimized performance, providing sufficient lift and control while minimizing the risk of rotor blade overload. This specification is crucial for training and operational scenarios where the aircraft may experience sudden power loss, necessitating pilots to be aware of their rotor limits. Understanding these limits aids in safe aircraft management and enhances the overall performance during critical flight situations.
