What is a functional requirement of an Electronic Chart Display and Information System (ECDIS)?

A functional requirement of an Electronic Chart Display and Information System (ECDIS) is that it can record track and user inputs. This functionality is crucial for navigation as it allows mariners to track their route, monitor their position, and make necessary adjustments based on real-time data. The ability to store this information also aids in analyzing previous journeys for future reference, enhancing safety and efficiency during maritime operations.

Recording user inputs and track information helps in maintaining navigational logs that adhere to maritime regulations and can be invaluable in the event of investigations or audits. This capability supports decision-making processes and reinforces situational awareness by providing a historical record of navigation.

While other options touch on various aspects of ECDIS, they do not represent essential functional requirements. For instance, ECDIS can display both vector and raster charts, and while it may require some level of oversight, it is designed to automate many processes. Additionally, power loss can affect ECDIS systems unless they are backed up by uninterruptible power supplies (UPS) or other power management systems. Hence, the ability to record track and user inputs stands out as a vital functional requirement.
