Question 936Navigation General

The correct answer is C) 20. Electronic Plotting Aids (EPAs) used on commercial vessels, such as those operated by the US Coast Guard, are typically capable of tracking up to 20 targets simultaneously. This capability is outlined in the performance standards for EPAs, which are established by the International Maritime Organization (IMO) and adopted by the US Coast Guard. The ability to track multiple targets is crucial for navigational safety, as it allows the vessel's crew to monitor the movement of surrounding ships and plan appropriate course adjustments to avoid collisions. The other answer choices are incorrect because 2 targets (option A) is too few, and 5 (option B) and 10 (option D) are less than the typical 20-target capability of modern EPAs.
