What is the update rate for static data when the vessel is underway on ECDIS?

• A. Every two minutes
• B. Every minute
• C. Every six minutes or on request
• D. Every fifteen minutes

Answer: (C)

The correct answer is that the update rate for static data when the vessel is underway on ECDIS is every six minutes or on request. Static data typically includes critical navigation information such as charts and maritime boundaries that do not change frequently. While the vessel is moving, it is important to maintain up-to-date information, but this static data can be refreshed less frequently than dynamic data, which changes more often, like vessel position or environmental conditions. The six-minute interval allows for a balance between ensuring that the information is current without overwhelming the system with excessive updates, particularly since much of this type of data remains constant. The option for updates "on request" means that if a navigator feels the need for more current static data due to specific operational requirements, they can initiate an update themselves. This ensures navigators have control over the information available to them without needing constant updates that may not be necessary for static data.
