Relative Vector Mode
The relative vector does not represent the true motion of the target, but its relative relation with own
ship. A target with its relative vector directed to own ship (passing through the CPA limit ring) will be a
dangerous target.
In the Relative Vector mode, it can be seen at a glance where the CPA limit of the dangerous target is.
