单选题What is TRUE of the history display of a target’s past positions on an ARPA?（）AIt provides a graphic display to emphasize which vessel is on a collision courseBIn the true presentation，it provides a quick visual check to determine if a vessel has changed courseCThe display is one of the primary inputs and must be in use when using the trial maneuver capabilityDIt provides a graphic display of a target vessel's relative course，speed，and CPA
单选题When using an ARPA，what should you consider in order to evaluate the information displayed?（）AThe target vessel's generated course and speed are based solely on radar inputsBNavigational constraints may require a target vessel to change courseCThe trial maneuver feature will automatically determine a course that will clear all targetsDYou cannot determine if a small target has been lost due to sea return
单选题Your ARPA has been tracking a target and has generated the targets course and speed.The radar did not receive a target echo on its last two scans due to the weather.What should you expect under these circumstances（）.AThe ARPA will generate data as if the target was still being tracked by radarBThe ARPA will give an audible and/or visual lost target alarmCThe ARPA will generate data based on sea return echoes from the vicinity where the target was lostDThe ARPA has lost all memory of the target and must recompute the target data
