Q

Which information determines if a NAVTEX message is to be rejected?

🔍 Key Concepts

• NAVTEX message header structure (station ID, subject indicator, message number) • How station ID and subject indicator letters are used for selection/rejection • Difference between message filtering by receiver settings vs. technical faults (like Answerback)

💭 Think About

• Look at which part of the NAVTEX header the operator can pre-select or de-select on the receiver to avoid getting unwanted messages. • Consider whether NAVTEX receivers normally allow you to block messages by station, by subject, by both, or only by one of these. • Think about how serial numbers (including 00) are used in NAVTEX—are they mainly for rejection, or for something else like repetition/special messages?

✅ Before You Answer

• Identify which header elements are actually used by the receiver’s filtering function (what you can turn on/off in the menu). • Verify whether Answerback is a Telex concept or something NAVTEX receivers rely on for selecting/rejecting messages. • Confirm the special purpose of serial number 00 in NAVTEX (is it normally rejected, or always accepted?).
