What component removes hydraulic pressure in the event of a fire near the nacelle?

The component that is responsible for removing hydraulic pressure in the event of a fire near the nacelle is the Emergency Shutoff Valve. This valve is designed to quickly isolate the hydraulic system from potential hazards, ensuring that hydraulic fluid does not contribute to the fire or create additional risks. By shutting off hydraulic flow, it helps to prevent further damage and enhances safety during emergency situations, particularly in case of a nacelle fire.

The FADEC (Full Authority Digital Engine Control) primarily manages the engine performance and operates the fuel control system but does not directly manage hydraulic systems in terms of fire response. The Hydraulic Control Unit is responsible for controlling and distributing hydraulic power for various systems but is not specifically designed for emergency shutoff in fire scenarios. The Engine Fuel Controller focuses on managing fuel flow and engine performance rather than hydraulic pressure. Thus, the Emergency Shutoff Valve is the appropriate answer for effectively addressing the need to remove hydraulic pressure in the case of a nacelle fire.
