Question 938Navigation General

The correct answer is D) All of the above. Electronic Plotting Aids (EPAs) used for navigation and collision avoidance on Coast Guard licensed vessels are required to have the following built-in functions: 1) Time of closest point of approach (TCPA) - to determine the time when a target vessel will be closest. 2) Plots of at least 10 targets at one time - to track multiple potential threats simultaneously. 3) Target trails - to visualize the movement of tracked targets over time. The other answer choices are incorrect because they do not capture all the required functionalities of an EPA as per the regulations governing navigation equipment on Coast Guard licensed vessels.
