AIS navigational status
AIS navigational status 10: Reserved for future amendment (WIG)
Reserved — linked to wing-in-ground craft carrying dangerous goods. What status 10 means, what speed and track should go with it, and how often it is simply wrong.
What status 10 means
Reserved for future amendment. The standard notes it for wing-in-ground craft carrying dangerous goods, harmful substances or marine pollutants.
What should go with it
Not meaningful — WIG craft are rare and this status is seldom seen.
Navigational status is entered by hand on the bridge; speed, course and position come from a satellite receiver. Read the status as testimony and the rest as measurement. Where they agree you have learned something. Where they disagree, the measurement is usually right.
How it goes wrong
If you see it on an ordinary ship, it is almost certainly a mis-set status.
