In AUTO mode, the Backup Pump is designed to provide redundancy in hydraulic systems by automatically engaging if a low pressure scenario is detected in both primary hydraulic systems A and B. This mechanism ensures that there is always a backup source of hydraulic pressure available for critical flight operations, which enhances safety and reliability in various phases of flight.

The Backup Pump’s function is essential because hydraulic systems are crucial for aircraft control surfaces, landing gear operation, and other important systems. By starting only when low pressure is identified, the Backup Pump conserves energy and avoids unnecessary wear when the primary systems are functioning properly, effectively balancing efficiency with safety.

This does not apply to the other scenarios, such as continuous running or operation strictly during ground use, as those would not align with the operational design intended for maintaining system integrity in flight. Similarly, closing hydraulic shutoff valves is not a function of the Backup Pump; rather, it relates to maintaining hydraulic system integrity rather than supplying hydraulic pressure.
