Which characteristic defines a double twist safety wire?

A double twist safety wire is characterized by its method of application, which involves twisting the wire tightly around the fastener or component being secured. This tight twisting creates a more secure bond, preventing any loosening due to vibration or movement. The double twist, in particular, refers to the way the wire wraps around itself, enhancing the overall strength and reliability of the safety mechanism.

This feature is crucial in aviation applications where components can experience significant stress and vibration. The added security provided by tight twists helps ensure that components remain securely fastened, thereby enhancing safety and performance. The construction of a double twist also means that it is less likely to slip or come undone compared to looser configurations.

In contrast, options that describe the wire as having no twists, being single-stranded, or easier to break do not accurately reflect the essential properties necessary for effective safety wire performance in aviation.
