2.17 Using the Offset EBL

The offset EBL can be used to predict a potential collision course. It can also be used to measure the range and bearing between two targets.

2.17.1 Predicting collision course

The procedure below may be used to check if a radar target is on a potential collision course with your vessel.

1.Press the EBL/VRM key to show the EBL/VRM soft keys.

2.Press the EBL1 ON soft key to turn on the EBL1.

3.Press the OFFSET soft key. The origin of EBL1 moves to the cursor position, which is marked with an “X.”

4.Use the Cursor pad to place the cursor on the radar target which looks like it might be on a collision course with own ship.

5.Push the ENTER knob to fix the origin position.

6.After waiting for a few minutes (at least three minutes), rotate the ENTER knob so the EBL bisects the target at the new position. If the target tracks along the EBL towards the center of the display (your ship’s position), the target may be on a collision course with your vessel.

To cancel the offset EBL, press the OFFSET soft key.
