How many characters does the short text messaging feature of the automatic identification system (AIS) allow for?

🔍 Key Concepts

• Automatic Identification System (AIS) message types related to safety or short text messaging • The typical maximum length, in characters, of an AIS safety‑related text message • How AIS encodes characters in a fixed-length message field

💭 Think About

• Think about standard AIS safety-related text messages defined in international standards—are they designed to be very long, or relatively short but sufficient for brief safety information? • Compare the options: which length best matches a brief safety alert (e.g., "SHOAL REPORTED NEAR 35-40N 075-20W") plus some extra detail, without being as long as an email or full report? • Consider that AIS uses a fixed-size character field for these messages; which of the options sounds most like a known specification limit rather than a rounded or guessed number?

✅ Before You Answer

• Confirm that you are thinking of AIS safety-related text messaging (not DSC, Inmarsat, or other GMDSS text services). • Make sure the number you pick would be a maximum capacity for one AIS safety-related message, not a typical or average length. • Before choosing, ask: "Does this number look like a specific standard limit used in AIS message definitions?" and verify it against your study materials or AIS specifications.
