hazardous, but may become so. (Warning may be escalated to alarm).
• Caution
Lowest priority of an alert. Awareness of a condition which still requires attention out of
the ordinary consideration of the situation or of given information.
Alerts are divided in different categories:
• Category A
Alerts for which graphical information at the task station (such as radar or ) directly
assigned to the function generating the alert. This is necessary as decision support for
the evaluation of the alert-related condition. These alerts can only be acknowledged at
the task station.
• Category B
Alerts where no additional information for decision support is necessary besides
the information which can be presented at the
CAM-HMI
. These alerts can be
acknowledged at the task station or at the
CAM-HMI
.
• Category C
Alerts that cannot be acknowledged on the bridge. These alerts require more
information about the status and treatment of the alerts (e.g. certain alerts from the
engine).
