Torque above what percentage indicates a system malfunction?

In the T-6A aircraft, the maximum torque limit is established to ensure safe and efficient operation of the engine and propulsion system. When torque levels exceed 100%, it signals to the pilots and maintenance crews that there may be a malfunction within the system, prompting a need for immediate attention.

Specifically, a torque indication above 100% is a critical threshold that suggests the engine is operating beyond its designated parameters, which could lead to potential damage and compromised safety. The industry standard for indicating a malfunction typically lies at 107%, as operating beyond this point enhances the risk of failure in mechanical components.

By recognizing 107% as the clear indication of system malfunction, operators can take necessary precautions to address any underlying issues before they escalate into serious problems. The other choices represent torque levels that are within normal operational limits or safety margins, implying they are not indicators of malfunction.
