Which hydraulic system has higher critical system demand?

Which hydraulic system has higher critical system demand?

• A. System A
• B. System B
• C. Both have equal demand
• D. Cannot determine

Answer: (B)

Critical system demand means the highest hydraulic load a system must supply during the most demanding scenario, including the combined flow and pressure needed to operate primary controls and other active components at once. In this case, the second system has the higher demand because it must meet the peak load for more actuators or for more critical functions simultaneously, especially under stressed conditions. It may be powering primary flight controls plus additional high-demand components, or it may have fewer redudant or buffering provisions, so the pump has to work harder to maintain the necessary pressure and flow. To compare systems, you’d look at how many actuators each system powers, how large their flow requirements are, and whether one system carries more critical loads (e.g., primary controls, braking, landing gear) during the same demanding scenario. When the second system bears the larger combined load, its critical demand is higher, which is why that option is selected. If you have specific load numbers or scenarios, you can plug them in to quantify exactly.
