Question 910Navigation General

The correct answer is A) Soundings. An ECDIS (Electronic Chart Display and Information System) is required to display various types of navigational information, including soundings or water depth measurements. This is a fundamental requirement specified in the regulations and standards governing ECDIS, as it provides critical information for safe navigation. The other answer choices are not correct because ECDIS is not required to display radar targets, waypoints, or meteorological data - those functions are typically handled by other specialized navigation systems and displays.
