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. 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 >.....<.
2. Operate the Trackball to bisect the target of interest with the EBL and read its distance at the
lower-left corner of the screen.
3. Press the
EBL
key to erase each EBL.
