What is the NR power-on takeoff maximum torque?

What is the NR power-on takeoff maximum torque?

• A. 95%
• B. 101-103%
• C. 103% max
• D. 108% (10 sec)

Answer: (C)

During power-on takeoff, you want enough torque to lift off quickly, but torque must be kept within limits to protect the engine and rotor system. The specification sets the takeoff maximum torque at a fixed 103% of the allowable torque, meaning you can use up to that level for a normal takeoff. The higher value of 108% is reserved for a brief transient period only and is not the standard takeoff limit. A range like 101–103% isn’t the official takeoff limit, and 95% would be more than sufficient only for non-takeoff conditions. So, the correct limit for NR power-on takeoff is 103% max.
