The fluid quantity switch on the hydraulic pump module activates the RSVR LOW caution indicating which condition?

• A. a loss of hydraulic fluid for that system (Leak) less than 60% of fluid remaining in the pump
• B. a loss of hydraulic fluid for that system more than 60% of fluid remaining in the pump
• C. a loss of hydraulic fluid for that system exactly 60% of fluid remaining in the pump
• D. no fluid loss detected in the hydraulic system

Answer: (A)

The fluid quantity switch in the hydraulic pump module monitors how much fluid remains in that system’s reservoir. When the level drops below 60 percent of the reservoir capacity, the switch triggers the RSVR LOW caution. This warns the crew of a low-fluid condition (likely from a leak or abnormal consumption) so you can address it before the pump runs dry or cavitates. If the fluid is above 60 percent, or exactly at 60 percent, the RSVR LOW caution would not be activated.
