Which component primarily provides hydraulic pressure for the cargo doors?

• A. Reservoir
• B. Electric pump
• C. Hand pump
• D. Accumulator

Answer: (B)

The electric pump is essential for providing hydraulic pressure to operate the cargo doors on the A320. It is designed to generate the necessary hydraulic fluid pressure to actuate the various components used for opening and closing the cargo doors. This electric pump is part of the aircraft's hydraulic system, which ensures efficient and reliable operation, especially during critical phases of ground handling. The reservoir stores hydraulic fluid but does not actively generate pressure. The hand pump, while capable of creating hydraulic pressure, is typically used in emergency situations rather than normal operation. An accumulator serves as a storage component for hydraulic fluid under pressure but does not create pressure itself; rather, it helps maintain pressure in the system when needed. In summary, the electric pump is the primary source of hydraulic pressure for the cargo doors, enabling smooth and controlled operation while ensuring safety and efficiency during ground operations.
