What is the purpose of a fairlead in aircraft systems?

A fairlead plays a crucial role in aircraft systems, specifically when dealing with control cables or other flexible lines. Its primary purpose is to guide the cable properly and prevent it from making contact with the aircraft's structure. By doing so, fairleads minimize the risk of abrasion and wear on the cable, which could lead to fraying or eventual failure. This is particularly important in maintaining the integrity and reliability of control systems that rely on these cables for effective operation.

By ensuring that cables are routed smoothly and securely, fairleads contribute to the overall safety and functionality of the aircraft, reducing maintenance needs and enhancing operational reliability. This is especially critical in high-stress areas where movement and vibration could cause cables to shift and potentially cause damage if not properly managed.
