1.18 Measuring the Bearing to a Target
Use the Electronic Bearing Lines (EBLs) to take bearings of targets. There are two EBLs, No. 1
and No. 2. Each EBL is a straight dashed line extending out from the own ship position up to the
circumference of the radar picture. The fine dashed line is the No. 1 EBL and the coarse dashed
one is the No. 2 EBL.
1.18.1 Measuring the bearing with an EBL
1. Press the EBL key to display either of the EBLs. Successively pressing the EBL key toggles
the active EBL between No. 1 and No. 2. The currently active marker is enclosed with >.....< in
the EBL indication box.
2. Operate the Trackball to bisect the target of interest with the EBL and read its bearing at the
lower-left corner of the screen.
3. You may “anchor” an EBL by choosing it and pressing the ENTER key.
4. To erase an EBL, make it active and press the CANCEL/HL OFF key.
