10.1 The CAM should handle alert information for
presentation on the CAM-HMI, including priority, state.
10.2 Alert information, including priority, state
should be distributed to appropriate functions and equipment carrying
out further processing or presentation (e.g., CAM-HMI).
10.3 The presentation of the alert on the bridge
equipment should be consistent as far as practicable with respect
to how alerts are displayed. Before presentation of an alert on any
HMI it should be checked wherever possible, whether the functions
and equipment may have the ability to evaluate and process the alert
with additional knowledge, regarding its presentation, priority, and
state. If this functionality is provided the CAM should support this
further processing. The presentation of an alert should take place
after the result of the processing could have been taken into consideration.
For INS, the requirements are specified in paragraph 21 of the Performance
standards for integrated navigation systems (INS) (resolution MSC.252(83)).
10.4 Only one CAM should be active on the bridge
at any one time, but it is allowed to display and operate the information
on multiple CAM-HMIs. The CAM functions may be centralized or partly
centralized in subsystems and interconnected via a standardized alert-related
communication.
