🔍 Key Concepts
• AIS static data vs. dynamic data requirements under SOLAS and IMO performance standards
• Difference between information that changes constantly (like position/heading) and information that rarely changes (like ship particulars)
• What data is actually transmitted in a standard AIS position report and voyage-related report
💭 Think About
• Which of these choices changes frequently and needs to be updated in real time for collision avoidance? Which are more ‘administrative’ details?
• Think about what information other ships need immediately on their AIS display to safely avoid you in restricted visibility.
• Consider which items are part of a voyage-related report (like destination and ETA) versus long-term details about the vessel.
✅ Before You Answer
• Review what AIS dynamic information includes (position, course, speed, heading, time stamp, navigation status).
• Review what AIS static and voyage-related information includes (MMSI, name, call sign, dimensions, type of ship, destination, ETA).
• Ask yourself: is port of origin a standard AIS field, or is it usually destination that is entered?
