The three hydraulic systems left, center, and right on the 787 are named to emphasize what?

• A. Redundancy and distributed hydraulic power for flight controls and systems.
• B. Color coding of fluid lines.
• C. Different hydraulic fluid types.
• D. The order of maintenance procedures.

Answer: (A)

Three hydraulic systems are named left, center, and right to highlight redundancy and distributed hydraulic power for flight controls and related systems. Each system provides independent power with its own pumps and reservoirs, feeding different control surfaces and equipment. If one system is inoperative, the others can still supply hydraulic power to maintain safe control and operation, which improves safety and reliability for flight control actuation and system functions. This architectural choice isn’t about color coding, different fluid types, or maintenance order—those aren’t what the naming conveys.
