1.17 Measuring the Bearing
Use the Electronic Bearing Lines (EBLs) to take bearings of a target. There are two EBLs, No.
1 and No. 2, which are toggled by successive presses of the EBL ON key. 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.
Press the EBL ON key to display either of the EBLs.
Successive presses of the EBL ON key toggle the active EBL between No. 1 and No. 2 and
the currently active EBL readout is circumscribed by >... <.
Rotate the EBL rotary control clockwise or counterclockwise until the active EBL bisects the
target of interest, and read its bearing at the lower-left corner of the screen.
The EBL readout is affixed by "R" (relative) if it is relative to own ship's heading, "T" (true) if
it is referenced to the north, as determined by RADAR 2 menu settings.
Each EBL carries a range marker, or a short line crossing the EBL at right angles and its
distance from the EBL origin is indicated at the VRM readout whether or not the
corresponding VRM is displayed. The range marker changes its position along the EBL with
the rotation of the VRM control.
Press the EBL OFF key to erase each EBL.
