When will AUTO Hydraulic Pumps start?

When will AUTO Hydraulic Pumps start?

• A. Switch is in AUTO
• B. AC Generator is Online
• C. Flaps are greater than 0
• D. Hydraulic pressure is normal

Answer: (A)

The key idea is that these hydraulic pumps have an AUTO setting that enables automatic operation. When the switch is in AUTO, the system will start the pump automatically as needed to maintain or supply hydraulic pressure for systems that rely on hydraulics, provided electrical power is available. That automatic action isn’t triggered just by having an AC generator online, or by flaps being extended, or simply because hydraulic pressure is already normal. Those conditions can influence demand or power availability, but they don’t initiate the automatic startup logic by themselves. So the reason the correct choice is that the pumps start when the switch is in AUTO is that this setting enables the automatic control that starts the pump as needed, rather than requiring manual activation or relying on other conditions alone.
