What happens to the hydraulic system if one pump fails?

The hydraulic system in an aircraft is typically designed with redundancy to ensure that if one pump fails, the remaining components can maintain functionality. In this scenario, if one pump fails, the overall hydraulic system can still operate normally because other pumps within the system can continue to provide the necessary hydraulic pressure required for operation. This redundancy allows for continued operation of essential systems, ensuring safety and reliability.

While other options suggest a total failure or partial functionality based on specific scenarios, having multiple hydraulic pumps means that the loss of one doesn’t necessarily lead to a complete loss of hydraulic power. Thus, the system is engineered to function effectively even with one pump out of service.
