If the parameter ”Type of Aids-to-Navigation” in Msg. 21 is different from “0 = Default, type of AtoN not specified”, the Inland-specific AtoN types as coded in the page 1 of the AtoN status bits must not be interpreted.
Page ID = 001 (1)
page id + code

| Bits | Description | Details |
|---|---|---|
| 5 | type of AtoN (0-31) | see table below |
In this case the matching Inland AIS AtoN virtual object shall be shown at the reported positon.
The Inland AIS AtoN symbols shall use the AIS diamond outline as depicted in the table below:

* For Inland AIS AtoN report the parameter “Name of Aids-to-Navigation” may be used to transmit the direction of impact of the AtoN. This information may be transmitted with or without preceding name value. In this case the content of the parameter contains two percent symbols ‘%%’ directly followed by the direction of impact in full degrees clockwise starting from North e.g. %%270 for direction of impact
The timeout for the display of Inland AIS AtoN shall be 6 times the recommended reporting interval i.e. 18 minutes.
After the timeout period the Inland AIS AtoN symbol shall be immediately removed from the chart and not displayed as lost target. For the AtoNs with an IENC match the charted object will be shown instead.
The following MID are used for the transmission of Inland AtoN information in page 1 of the AtoN status bits in AIS message 21 in Europe:
