Which risk increases when hydraulic actuators used in aircraft landing gear experience low reservoir pressure?

💡 Explanation

A low reservoir causes air ingestion leading to cavitation within the actuator's hydraulic fluid. The compressibility increases, which reduces actuator stiffness because the pressure amplification from the valves cannot apply adequate force preventing rapid uncontrolled gear free fall, rather than gradual controlled lowering.
