What option does an Electronic Plotting Aid (EPA) not have?

AI Explanation
The correct answer is D) Trial Maneuver. Electronic Plotting Aids (EPAs) do not typically have the capability to perform trial maneuvers, which allow the user to simulate potential course and speed changes to evaluate their impact on the vessel's closest point of approach (CPA) and time to CPA (TCPA) with other targets. This functionality is usually found on more advanced Automatic Radar Plotting Aid (ARPA) systems, but is not a standard feature of basic EPA systems. The other options listed (preset CPA/TCPA, dual VRMs/EBLs, and target trails) are common features found on most EPA systems to assist the user in collision avoidance and navigation.
