Integrated Navigation Test 2 Practice

Which of the following statements about AIS information such as destination and ETA is true?

It can be trusted with 100% accuracy It should be treated with caution It is always inaccurate It is never transmitted

Correct Answer:

It should be treated with caution

Explanation:

AIS data for destination and ETA is a useful reference, but it isn’t guaranteed to be accurate. These details can change with speed adjustments, new routing, port calls, or delays, and there can be delays or errors in how the data is reported or updated. Some vessels may also have AIS off or send incomplete information, and human error or intentional misreporting can occur. Because of these factors, you should treat AIS destination and ETA with caution and corroborate it with other sources like radar, direct communications with the vessel, and official port or voyage information. The other statements are too absolute: AIS is not always inaccurate, it is widely transmitted, and it isn’t guaranteed to be 100% correct at all times.
