4 OPERATION
4.1 General
The AI80, once activated, will continuously and autonomously
broadcast the vessel’s position and all the static and dynamic
information as required by IMO.
However, while the vessel’s speed and rate of turn manoeuvres will
automatically determine the update rate, there remains a need for the
Master or an authorized person to manually input, at the start of the
voyage and whenever changes occur, the following voyage related
data:
•
ship’s draught
•
type of hazardous cargo (most significant hazard carried)
•
destination and ETA (at master’s discretion)
•
the correct and actual navigational status
•
safety related short messages, when appropriate
Refer Changing parameters during operation , page 41 onwards.
Caution!
The Officer on Watch (OOW) should always be aware that
other ships and, in particular, leisure craft, fishing boats and
warships, and some coastal shore stations including Vessel
Traffic Service (VTS) centres, might not be fitted with AIS. The
OOW should also be aware that AIS fitted on other ships as a
mandatory carriage requirement, might, under certain
circumstances, be switched off on the Master’s professional
judgment.
An AIS system should always be in operation. It is recommended that
the AIS is not switched off during port stays because of the value of
the ship information to port authorities.
Whether at sea or in port, if the Master believes that the continued
operation of AIS might compromise the ship’s safety or security, the
VHF transmitting may be switched off as described in
Turning the
VHF transmitter OFF , page 41. This might be the case in sea areas
where pirates and armed robbers are known to operate.
However, the VHF transmitting should be re-activated as soon as the
source of danger has disappeared.
