How to Measure Bearing
The Electronic Bearing Lines (EBLs) are used to take bearings of targets.There are
two EBLs, EBL1 and EBL2. Each EBL is a straight dashed line extending out from the
own ship position up to the circumference of the radar picture. The two EBLs can be
distinguished from each other by the different lengths of their dashes; the dashes on
EBL2 are longer.
Each EBL has an EBRL (Electronic Bearing Range Line, indicated as a short line,
crossing the EBL at right angles). When VRM is not displayed and only EBL is dis-
played, the EBRL shows the range from the EBL origin.
When VRMs are displayed with EBLs the VRM overlaps the EBRL. The value for
EBRL and VRM is the same and is displayed in the VRM box at the bottom-right of the
screen.
