Which risk increases when a hydraulic actuator on an aircraft's landing gear experiences erratic supply pressures?

💡 Explanation

Hydraulic lock results where fluid gets trapped inside a cylinder because seals block proper flow. The mechanism of hydraulic lock causes jammed linear motion because thermal expansion exacerbates the trapping, therefore preventing retraction of landing gear, rather than other thermal concerns.
