3.3.2 Relative Vector Mode
(see Figure: Figure: 3−10)
Relative vector mode shows how targets move in relation to own.
All ships that have relative vectors pointing to my own ship are dangerous
targets.
When the same situation is displayed in RELATIVE vector mode, target 1 gradu-
ally closing with own ship and it is apparent that target 2 indicates no threat as
long as neither own ship nor target changed their headings.
The stationary target 3 does not move at all. Its relative vector is exactly oppo-
site to own ship’s vector.
