Which Radar and ECDIS Functionalities Do Nautical Officers Really Need in Certain Navigational Situations?
Today’s navigation systems risk information overload and display clutter due to the multitude of available functionalities and information. Different navigational situations present differing challenges to the navigator, because of varying traffic or maneuvering conditions. This suggests that the ne...
