Navigation General · Electronic Nav — AIS Data
Which AIS information is entered manually and therefore most prone to error?
- AGPS position
- BCourse over ground
- CStatic/voyage data such as destination, draft, and ship name✓ Correct
- DSpeed over ground
Explanation
Dynamic data (position, COG, SOG, heading) comes from sensors automatically. Static and voyage-related data (name, type, dimensions, destination, ETA, draft) are entered by the crew and may be outdated or wrong, so they should be verified, not trusted blindly.
