What component on the A340-500 provides hydraulic pressure to the Swivel Selector Valve if the primary supply fails?

Question

BlackTom AI · Accepted Answer

Question restatement: What component on the A340-500 provides hydraulic pressure to the Swivel Selector Valve if the primary supply fails?

Option 1: Change-Up Valve
Reasoning: A Change-Up Valve would imply an alternate path that increases pressure from a secondary source, but this term is not the standard designation for providing hydraulic pressure to the Swivel Selector Valve in the event of primary supply failure. It does not align with the established nomenclature in Airbus hydraulic system schematics for this role.

Option 2: Change-Over Valve
Reasoning: The Change-Over Valve is the component that autonomously switches the hydraulic pressure source to the Swivel Selector Valve when the primary supply is unavailable. This valve is specifically designed to ensure continued operation by routing pressure from an alternate hydraulic source, which matches the described function.

Option 3: Stand-By Valve
Reasoning: A Stand-By Valve could imply a backup function, but the term commonly used for delivering pressure to a specific actuator/valve during a supply failure is Change-Over. The Stand-By Valve does not precisely capture the intended role of providing hydraulic pressure to the Swivel Selector Valve in the failure scenario.

Option 4: Stand-Up Valve
Reasoning: Stand-Up Valve is not a recognized designation for the hydraulic path that supplies pressure to the Swivel Selector Valve in the event of primary supply failure. The terminology does not reflect the substitution mechanism required for continuing operation.

Summary: Among the given options, the Change-Over Valve is the correct component responsible for providing hydraulic pressure to the Swivel Selector Valve when the primary supply fails. The other options misidentify the function or use nonstandard terminology that does not correspond to the Airbus hydraulic system architecture for this scenario.
