The most commonly used type of aircraft control cable is the extra flexible 7 x 19 stainless steel cable. This cable design features 19 strands of wire in a configuration of seven bundles, which provides a high degree of flexibility and resistance to fatigue. The configuration allows the cable to bend easily around pulleys and various control mechanisms in aircraft systems, making it an ideal choice for applications that require frequent movement and adjustments.

Stainless steel is chosen for its excellent strength-to-weight ratio and inherent corrosion resistance, which is critical for maintaining the safety and durability of control systems in various environmental conditions. Given these properties, the 7 x 19 stainless steel cable is favored in the aviation industry for use in a wide range of control systems, such as those for ailerons, elevators, and rudders, where reliable performance is essential.

While other types of cables may be used in specific applications or for particular requirements, the balance of strength, flexibility, and resistance to wear makes this cable the standard choice for most aircraft control applications.
