Operation
3.17.2 Target vessel details display in Inland AIS mode
Additional detail relating to target vessels is available when operating in Inland AIS mode. The additional
information is only displayed for target vessels which are also equipped with an Inland AIS transceiver and are
transmitting inland AIS data.
The target vessel details display described in section 3.5 will show the following additional data:
● Blue sign status is displayed as either 'Yes' (the sign is set), 'No' (the sign is not set) or 'not available'.
● The IMO number is not shown for Inland target vessels, the ENI (unique European Vessel
Identification Number) for the vessel is shown instead.
● The target vessels call sign shows its ATIS code.
● The displayed dimensions of the vessel are the maximum rectangular size of the convoy.
● The target vessel destination is displayed as a UN location code and ERI terminal code.
● The ship (or combination type) is shown using an ERI classification code. A table of ERI codes is
provided in section 8 for reference.
● The load status of the vessel is displayed as 'Loaded' or 'Unloaded'
● Quality of speed, course and heading information will be shown as 'high' when the target vessel is
using an approved sensor to generate this data, or low if the data is derived from internal GNSS only.
● The number of crew, passengers and other shipboard personnel will be displayed.
3.17.3 Setting voyage data in Inland AIS mode
Additional voyage related information is required for Inland operation along with some changes to the standard
AIS configuration. The following additional information must be entered into the AIS transceiver:
● The vessels load status as 'loaded' or 'unloaded'.
● The number of blue cones or blue flag status for the cargo (1, 2 or 3 blue cones, or blue flag).
● The static draught of the vessel to the nearest centimetre.
● The air draught of the vessel to the nearest centimetre.
● The number of crew (0 to 254 or unknown), passengers (0 to 8190 or unknown) and other shipboard
personnel (0 to 254 or unknown).
● The number of assisting tugboats (from 0 to 6).
The additional identification information can be entered via the main menu. Press the 'Menu' key then select
the 'Voyage data' sub-menu. When the AIS transceiver is operating in Inland AIS mode the voyage data entry
screen will be extended to allow input of the additional information described above.
The following standard AIS voyage information must be updated for Inland AIS:
● Destination
The voyage destination should be entered using UN terminal location codes and ERI terminal codes where
possible.
3.17.4 Blue sign operation
A 'blue sign' switch may optionally be connected to the AIS transceiver during installation. This switch sets the
'blue sign' status in transmitted inland AIS position reports to either 'Set' or 'Not set'. If a blue sign switch is not
installed the blue sign status is transmitted as 'not available'.
If a blue sign switch is installed it should be set according to the current navigational situation. The current blue
sign status will be displayed on the own vessel data screen.
