🔍 Key Concepts

• NAVTEX message categories (A, B, C, D, etc.) and which are mandatory under GMDSS/SOLAS • The role of Inmarsat-C (EGC SafetyNET) versus NAVTEX in providing Maritime Safety Information (MSI) • What types of messages are considered vital to safety of navigation and life at sea and therefore should never be filtered out

💭 Think About

• If Inmarsat-C is inoperative, which system is now your only automatic MSI source in that sea area? What does that imply about filtering messages? • Look at the listed categories: which ones relate directly to immediate safety of navigation or life-saving information, as opposed to more routine or supplementary information? • Think of the SOLAS requirement: which message categories are specified as those a ship must always be able to receive automatically, without operator selection?

✅ Before You Answer

• Identify which NAVTEX categories correspond to navigational warnings, meteorological warnings/forecasts, ice reports, and SAR information and note which are mandatory. • Confirm which categories SOLAS/GMDSS allow you to optionally disable (e.g., certain routine or commercial messages) versus those that must remain enabled. • Before choosing, check that your selected option includes all of the critical safety categories that would be lost if Inmarsat-C SafetyNET is unavailable.
