Which statement is true regarding LES codes in Inmarsat systems?

• A. LES code updates are necessary only when switching ocean regions.
• B. The SAR jurisdiction software updates the hot-key menu automatically.
• C. LES code is determined by NAVAREA based on vessel position.
• D. LES codes must be updated by officers depending on SAR jurisdiction.

Answer: (D)

The correct statement regarding LES codes in Inmarsat systems is that LES codes must be updated by officers depending on Search and Rescue (SAR) jurisdiction. Inmarsat employs Land Earth Stations (LES) to facilitate communication between maritime vessels and ground stations, and these codes are crucial for directing distress signals to the appropriate SAR authority effectively. As vessels travel across different areas, their operational jurisdiction can change, which may require an update of the LES codes to ensure that emergency communications are routed to the correct SAR agencies. This reflects the dynamic nature of maritime operations, where a vessel might enter or leave different SAR jurisdictions based on its geographic location. In contrast, the other statements do not accurately describe how LES codes function. For instance, LES code updates are not limited to just switching ocean regions; they reflect the vessel's operational requirements. While the SAR jurisdiction software may provide assistance, it does not automatically update the hot-key menu without officer intervention. Additionally, while NAVAREA is important for maritime safety, LES codes are not strictly dependent on it, as they relate more specifically to SAR operations rather than navigation areas.
