Alert related to SOG, COG, speed and heading components
It is possible that the operator has not chosen any speed or heading sensors, or that
the chosen sensors do not have any valid values. This kind of a situation is critical for
the system, because it cannot even perform dead reckoning.
When no heading source is available, the system generates the Alert 30601 "Heading
Sensor Not Available."
When no speed source is available, the system generates the Alert 30601 "SDME
Sensor Not Available."
When no COG/SOG data is available, the system generates the Alert 30601 "COG/
SOG Not Available."
