Which items are listed under Hydraulic Pumps?

• A. Hydraulic Pump #1
• B. Hydraulic Pump #2
• C. Backup Hydraulic Pump
• D. All of the above

Answer: (D)

Hydraulic pumps include every device that generates hydraulic pressure for the helicopter’s systems. In the UH-60S, that means both engine-driven pumps (one on each engine) and the backup hydraulic pump. The two engine-driven pumps provide normal hydraulic power, while the backup pump supplies pressure if the primary pumps aren’t available or during redundancy operations. Since all three are listed under Hydraulic Pumps, the correct understanding is that all of these items belong in that category. Focusing on any single pump would miss the other primary and backup sources that the system relies on for continuous operation.
