The master may，at his/her discretion，turn off the AIS if he/she believes that it may compromise the safety or security of the vessel

Under no circumstances shall AIS be turned off while underway as this could endanger the vessel and those around her

AIS is always required to be operating if the vessel is in or in the vicinity of a VTS area

AIS is a short-range VHF-FM system that automatically broadcasts a vessel's position，course，speed and other safety related information to all those with similar equipment in the area

AIS is a one-way centrally managed system that requires the local VTS to send commands to instruct each vessel to broadcast position，course，speed and other safety related information to all those with similar equipment in the area

AIS is a global tracking system that relies upon INMARSAT C service to communicate vessel position，course，speed and other safety related information to all those with similar equipment in the area

AIS is a short-range 3 cm X-band radar system that automatically sends a vessel's position，course，speed and other safety related information to all those with similar equipment within the area

AIS may be used to make passing arrangements via ship-to-ship text messaging thus relieving a vessel operator from sounding whistle signals or making contact via radiotelephone

AIS may be used to make passing arrangements via ship-to-ship text messaging but a vessel operator is still required to sound whistle signals unless the arrangement is made via radiotelephone

AIS cannot be used to make passing arrangements because the system does not have the ability to communicate from ship-to-ship in this manner

AIS cannot be used to make passing arrangements because the use of the ship-to-ship text messaging feature in this way is prohibited

It is built by Automatic Tuning Optimizer.

It cannot be stored persistently in the data dictionary.

It can be used by the query optimizer automatically.

It can be created manually by using the CREATE PROFILE command.

AIS cannot be used to make passing arrangements because the system is not capable of this type of ship-to-ship communications

AIS cannot be used to make passing arrangements because the ship-to-ship text messaging feature is for emergency use only

AIS can be used to make passing arrangements via ship-to-ship text messaging but a vessel operator is not relieved from the requirement to sound whistle signals or make arrangements via bridge-to-bridge radiotelephone

AIS can be used to make passing arrangements via ship-to-ship text massaging thus relieving a vessel operator from making such arrangements via bridge-to-bridge radiotelephone or signaling intent to pass via whistle signals
