CPA Graphical Display
When a target is converging and has a CPA shown, the
CPA
button is available on the
target display. This button brings up a graphical plot showing the relative position of the
target at the time of CPA.
The display is oriented either Heading-Up or North-Up depending on the current profile
settings. If heading data is not available for your vessel, then it is oriented course-up. The
heading or course may be displayed in magnetic or true degrees depending on a setting in
setup mode.
Important notes:
1. No other targets are shown on this display. Only the current target and your vessel
are displayed.
2. The plotting distance shown on the screen between your vessel and the target is
always the same regardless of the actual CPA. Always use the CPA value displayed
to confirm the expected distance at the time of closest point of approach.
