Target data

Place the cursor on the plotted target and press the ENTER/SELECT key. Vector reference, vec- tor time, vector time elapsed, and selected target’s bearing, course, speed, CPA and TCPA appear at bottom of the display.

In the head-up mode target bearing course and speed become true or relative depending on vec- tor reference setting. In north-up, course-up and true motion the target data always shows true bearing, true course and speed over the ground.

True or relative vector

Target vectors can be displayed relative to own ship (relative) or with reference to the north (True). Current vector reference appears at the bottom of the display when the PLOT mode is active.
