Question 804Navigation General

The correct answer is A) Navigational constraints may require a target vessel to change course. When using an Electronic Plotting Aid (EPA), it's important to consider navigational constraints that may impact a target vessel's course. EPAs display a calculated course and speed for detected targets, but these projections may not account for factors like traffic, weather, or the need to avoid hazards. The target vessel may need to deviate from the displayed course due to these real-world navigational considerations. The other answer choices are incorrect because: B) EPAs do not automatically determine a course to clear all targets, C) EPAs can be affected by sea return and may lose small targets, and D) the target's course and speed are based on radar inputs, not solely on the EPA's calculations.
