Question 905Navigation General70% to pass

Which of the following data layer categories is NOT displayed on ECDIS?

AI Explanation
The correct answer is B) Ship hydrodynamic information. ECDIS (Electronic Chart Display and Information System) displays various data layers as required by regulations, but ship hydrodynamic information is not one of them. ECDIS is primarily focused on displaying navigational data such as Hydrographic Office data, Notice to Mariners information, and ECDIS warnings and messages. Ship hydrodynamic information, which relates to the vessel's maneuvering characteristics, is not a required data layer for ECDIS and is not typically displayed on the system.
