An electronic torque indicating system consists of what primary components?

An electronic torque indicating system fundamentally relies on a cockpit indicator and a transducer to measure and display the torque applied to an aircraft engine or component. The transducer serves as the sensor that detects torque through the application of strain gauges or other measuring methods, converting that mechanical force into an electrical signal. This electrical signal is then transmitted to the cockpit indicator, which processes the data and displays it in a user-friendly format for the pilot or technician to monitor.

This combination is critical in ensuring accurate torque measurement for applications like engine assembly or maintenance, where precise torque settings are vital for safety and functionality. The electronic nature of the system allows for real-time readings, enhancing operational efficiency and reducing the likelihood of human error.

The other options involve components that, while relevant in different contexts, do not primarily form an electronic torque indicating system. For example, a torque wrench and calibration unit focus on manual torque application and periodic verification rather than electronic measurement. A computer and data logger might be used in conjunction with various systems but are not specific to torque indication alone. Lastly, a speedometer and tachometer measure speed and rotational speed, respectively, and do not relate to torque measurement directly.
