What Are Aircraft Control Cables

Aircraft control cables are a common aspect of modern aviation design, providing a reliable means of transmitting force to various control surfaces and equipment for the smooth execution of commands from pilots and cockpit systems. With a role in supporting the control and motion of equipment ranging from ailerons and elevators to landing gear assemblies, it is paramount that any pilot, mechanic, or enthusiast familiarize themselves with these components. As we will cover the basic materials, types, and applications surrounding aircraft control cables in this blog, read on if you would like to receive a basic overview for making informed purchasing decisions.

In the early days of aviation, aircraft and their onboard equipment were often controlled using rigid push-pull rods or similar mechanisms, which were somewhat limited in their ability to navigate complex routes and support the needs of increasingly larger and intricate designs. The development of aircraft cables provided a more adaptable solution, allowing for more intricate and reliable control systems that benefited from an ample balance of flexibility and strength. Today, aircraft cables are used in models ranging from light aircraft to large commercial airliners, as well as military aircraft where they must perform under the most demanding conditions without fail.

One of the primary considerations in the initial design of aircraft cables is the material from which they are made. The most common options used in the construction of aircraft cables are stainless steel and galvanized steel, both of which offer distinct characteristics that benefit certain needs. For example, a stainless steel cable will be highly resistant to corrosion and have excellent durability, making it a suitable choice in locations where the cable may be exposed to moisture or other corrosive elements. Galvanized steel, on the other hand, is coated with a layer of zinc to provide specific protection against rust and corrosion, which is a concern for many aviation assemblies. While not as inherently resistant to corrosion as stainless steel, galvanized steel is beneficial for less demanding operations, where budget restrictions may be a factor.

The construction of aircraft cables will generally involve twisting multiple strands of wire together to form a rope. The most common construction designs are “7x7” and “7x19,” which refer to the number of wires per strand in each cable. For example, a 7x7 aircraft cable consists of seven strands, each made up of seven wires. This offers a good balance of strength and flexibility, finding ample use in settings where moderate bending is necessary for optimal functionality. Meanwhile, a 7x19 cable will consist of seven strands that are each made up of nineteen wires, resulting in greater flexibility that is useful for navigating tight bends.

While aircraft cables are most widely recognized for their application in control systems, they also perform other important roles. For example, cables can be used to secure cargo, lift heavy loads, and support select safety systems. Regardless of where or how they may be employed, these cables always provide the key benefits of strength, flexibility, and durability for a reliable means of carrying out tasks and executing control commands.
