1.33 Collision Assessment by Offset EBL
The origin of the EBL can be placed anywhere with the Touchpad to enable measure-
ment of range and bearing between any two targets. This function is also useful for
assessment of the potential risk of collision. It is possible to read CPA (Closest Point
of Approach) by using a VRM as shown in (a) in the illustration below. If the EBL pass-
es through the sweep origin (own ship) as shown in (b) in the illustration below, the
target ship is on a collision course.
