### (a) Explanation of How the Reserve of Fluid in the System is Checked and How Make-Up is Achieved
The reserve of fluid in a hydraulic steering gear system is critical for maintaining operational integrity, preventing cavitation, and ensuring the longevity of components. Its status is rigorously monitored, and make-up is meticulously managed.
* **Checking the Reserve of Fluid:**
* **Visual Level Indicators (Sight Glass):** The most common and primary method involves a transparent sight glass or level gauge affixed to the side of the main hydraulic reservoir (often called the header tank or make-up tank). This allows for a direct, visual inspection of the fluid level. The sight glass typically has clearly marked 'MIN' and 'MAX' operating levels. Daily visual checks by the duty engineer are standard practice and recorded in the engine room logbook.
