The term 'cable' in aircraft electrical installations is defined as including:

• A. All answers are correct
• B. 2 or more separately insulated conductors in the same jacket
• C. 2 or more separately insulated conductors twisted together
• D. one or more insulated conductors covered with a metallic braided shield

Answer: (A)

In aircraft electrical terminology, a cable is an assembly that groups two or more insulated conductors used together and is protected or arranged for a common purpose. The scenarios described—two or more conductors in the same jacket, two or more conductors twisted together, and insulated conductors covered with a metallic braided shield—each fit that broad idea, since they all involve multiple conductors bundled for a single installation and provide some form of protection or shielding. Because all of those configurations meet the definition of cable, the best answer is that all of them are included. (A single conductor by itself would be considered wire, not cable.)
