Where does the emergency hydraulic system derive its pressure from?

• A. Battery bus
• B. Primary hydraulic pump
• C. Emergency Accumulator
• D. Engine-driven compressor

Answer: (C)

The emergency hydraulic system derives its pressure from the emergency accumulator. This component is designed to store hydraulic fluid under pressure, which can then be released to provide hydraulic power when needed, especially in situations where the primary hydraulic system fails or is compromised. The emergency accumulator serves as a backup source, allowing critical flight control surfaces and other essential systems to operate safely even if the main hydraulic system loses pressure. This capability ensures that pilots maintain control over the aircraft in emergency scenarios, highlighting the importance of redundancy in aircraft design for safety reasons.
