The Navi-sailor 4000 ECDIS is capable of displaying which of the following targets?

• A. AIS target
• B. ARPA target
• C. Both AIS and ARPA targets
• D. All of the above

Answer: (D)

Integrated navigation displays aim to show all available target types on one screen, so you can see traffic clearly. AIS targets come from the vessel’s AIS broadcasts and provide identity and basic motion data for other ships. ARPA targets come from radar tracking and include predictive information like CPA and TCPA. The Navi-sailor 4000 ECDIS is built to combine radar ARPA data with AIS data, allowing you to view both types of targets on the chart at the same time. Because it supports both, it can display all of the target types available, which is why the best choice is that it can display both AIS and ARPA targets.
