What type of alarms are activated when there is a deviation from the planned route in ECDIS?

• A. Approach to Critical Point alarms
• B. Route Monitoring alarms
• C. Malfunction alarms
• D. All of the above

Answer: (B)

Route Monitoring alarms are specifically designed to alert the crew when there is a deviation from the planned route in ECDIS. These alarms are an essential safety feature that ensures maritime navigation remains within defined parameters, allowing for timely corrective actions to be taken to avoid potential hazards. Route Monitoring alarms continuously compare the vessel’s current position and heading with the electronic chart data and the planned route. If the system detects that the vessel has strayed from the planned trajectory, the alarms will activate. This functionality is critical for maintaining situational awareness and ensuring safe navigation, especially in busy or risky waters. The other types of alarms mentioned serve different purposes. Approach to Critical Point alarms are activated when the vessel approaches predefined critical navigational points, such as waypoints or turning points, indicating the need for an operational check. Malfunction alarms indicate system failures or errors within ECDIS and are unrelated to navigational deviations. While they are important, they do not serve the specific function of alerting to route deviations like Route Monitoring alarms do.
