Details: 

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:

	CODE	CEVNI CODE	ON POS-0	MIS-M	OFF POS-F	VIRT-V	NAME
fixed aids, landmarks	1	4.A + 4.B					Channel near the right bank
	2	5.A + 5.B					Channel near the left bank
	3	4.C + 4.D					Cross-over right bank
	4	5.C + 5D					Cross-over left bank
	5	8.C - 8.C2					Bridge pillar

* 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:
