Which control surfaces are powered by the right hydraulic system?

The correct choice identifies the outboard multifunctional spoilers and thrust reversers as being powered by the right hydraulic system. In aircraft systems, hydraulic power is essential for the operation of various control surfaces and mechanisms, and each hydraulic system is typically designated for specific components.

In this case, the outboard multifunctional spoilers are designed to enhance control and handling during various phases of flight, particularly during roll maneuvers. The thrust reversers are critical for deceleration after landing, providing a means for the aircraft to slow down efficiently. By being powered by the right hydraulic system, these systems ensure that the aircraft maintains operational efficiency and safety.

Understanding the function of hydraulic systems in aviation provides clarity on why specific components are powered by designated systems. Each hydraulic system is configured to operate distinct functions, which is why this choice properly aligns with the operational requirements of the aircraft.
