- A compact UTC timestamp — day, hour and minute followed by Z — such as 201500Z for the 20th at 15:00 UTC.
- Track line joining
- Introduces a route through a series of positions — a cable route, a tow's track or a survey line.

- How warnings write positions: degrees, a hyphen, then minutes, with N/S and E/W — 49-40.8N 003-43.8W.

- CANCEL THIS MSG
- The warning's own expiry: a line telling the reader when the message cancels itself.
