Question 899Navigation General

The correct answer is A) In the true presentation, it provides a quick visual check to determine if a vessel has changed course. The history display of a target's past positions on an ARPA (Automatic Radar Plotting Aid) is designed to show the target's track over a period of time, which allows the user to quickly assess if the target has changed course. This visual representation helps the user determine the target's maneuvering behavior, which is crucial for collision avoidance. The other options are incorrect because: B) refers to the relative motion display, C) is related to the trial maneuver capability, and D) is not the primary purpose of the history display.
