What is the function of a cable tension regulator?

The function of a cable tension regulator is primarily to automatically adjust cable tension based on changes in temperature. As temperatures fluctuate, materials can expand or contract, which may affect the tension in flight control cables. The regulator helps to compensate for these changes, ensuring that the tension remains within safe and operational limits. This automatic adjustment is critical for maintaining proper control responsiveness and preventing mechanical failures that could arise from inadequate or excessive cable tension.

Measuring tension, maintaining constant speed in cable movement, and alerting pilots about insufficient tension are important aspects of cable management, but they do not capture the primary role of a tension regulator, which centers on adjusting the tension itself in response to environmental changes.
