What emergency feature does ECDIS typically include?

The inclusion of an emergency power supply in ECDIS (Electronic Chart Display and Information System) is crucial for ensuring continuous operation during power failures or fluctuations. This feature allows the system to maintain its functionality and provide critical navigation information, which is vital for the safety of the vessel and crew. During emergencies, having access to updated navigational charts and related data can assist the crew in making informed decisions, enhancing situational awareness, and taking necessary actions to avoid accidents or hazards.

While other features, such as automatic course correction, built-in GPS navigation, and real-time weather alerts, are significant components of navigation systems, they do not specifically serve the immediate purpose of maintaining operation during an emergency. The emergency power supply is essential for ensuring that all navigation aids remain operational when they are needed most, thereby enhancing overall maritime safety.
