Which component is used to transport liquids or gases between parts of the aircraft system?

• A. Hoses
• B. Tubing
• C. Inspection Mirror
• D. Safety Cable

Answer: (B)

Transporting liquids or gases between parts of an aircraft system relies on a dedicated conduit that provides a continuous path for the fluid to move from one component to another. Tubing serves this role by forming a reliable, leak‑tight route that can be routed through the airframe and connected with proper fittings to seal each end. It can be metal or plastic and is chosen for its ability to maintain a controlled flow between components in hydraulic, fuel, or pneumatic systems. Hoses, while also used to move fluids, are more flexible and typically used where movement, vibration, or dynamic routing is involved. The other items aren’t used to carry fluids at all—an inspection mirror is a viewing tool, and a safety cable is for securing parts.
