Which component does the cockpit servo switch control on the filter group assembly?

• A. PDI
• B. Over pressurization valve
• C. Bypass valve
• D. Shutoff valve

Answer: (D)

The cockpit servo switch is primarily responsible for controlling the shutoff valve within the filter group assembly. The shutoff valve plays a crucial role in regulating fluid flow, enabling the pilot to manage system performance and ensure operational integrity. By using the cockpit servo switch to operate the shutoff valve, pilots can effectively isolate sections of the hydraulic system during maintenance or emergencies, thereby preventing fluid leaks and maintaining system safety. Other components such as the PDI, over pressurization valve, and bypass valve serve their unique purposes in the hydraulic system but are not directly controlled by the cockpit servo switch. The PDI (Pressure Differential Indicator) typically provides feedback on system pressure conditions, the over pressurization valve functions to release excess pressure to protect system integrity, and the bypass valve is used to redirect flow if needed. Their operation is crucial but does not involve direct manipulation through the cockpit servo switch like that of the shutoff valve.
