What should be monitored if an IDG fault light illuminates?

Monitoring temperature and torque conditions is crucial if an IDG (Integrated Drive Generator) fault light illuminates because the IDG is responsible for converting the mechanical energy from the engine into electrical energy. An IDG fault often indicates an issue with the generator's function, which can lead to abnormal temperature levels and torque constraints that may affect its operation.

Elevated temperatures can signify overheating within the generator or mechanical components, potentially resulting in failure if not addressed. Similarly, torque conditions should be monitored to ensure that the generator is functioning correctly within the designed limits. Any discrepancies could indicate mechanical failure that requires immediate attention to prevent further damage or loss of electrical power.

This focus on temperature and torque helps maintain safety and functionality during flight operations, directly tying into the reliability of the aircraft’s electrical systems. Hydraulics, engine performance, and electrical flow are also important aspects of aircraft operation, but in the context of an IDG fault light, temperature and torque are the primary indicators of the specific issues that may arise from that fault.
