What is a sway brace?

A sway brace is an adjustable bracket specifically designed to prevent damage from components swinging or shifting under G-loading conditions during flight. When aircraft undergo maneuvers that generate significant forces, such as sharp turns or abrupt changes in speed, it is crucial to secure various components to mitigate the risk of structural damage or failure. The sway brace helps maintain stability and alignment of these components, ensuring that they remain properly positioned and do not swing freely, which could lead to harmful impacts or vibrations that might compromise the aircraft's performance and safety.

The other options, while they may relate to military aircraft and equipment, do not accurately define what a sway brace is or its primary function. The focus of the sway brace on G-loading dynamics is key to understanding its importance in aircraft systems and design.
