1.20 Measuring Range and Bearing Between Two
Targets
1. Press the [EBL OFFSET] key, and place the origin of the No. 1 EBL, for example, on a
target of interest (target 1 in the illustrated example), by operating the trackball.
2. Turn the EBL control until the EBL passes through another target of interest (target 2).
3. Turn the VRM control until the range marker aligns with target 2. The active VRM
readout at the lower-right corner of the screen indicates the distance between the two
targets.
You can repeat the same procedure on third and fourth targets by using the No. 2 EBL
and No. 2 VRM.
Bearing is shown relative to own ship with suffix “R” or as a true bearing with the suffix
“T” depending on EBL relative/true settings on the RADAR 1 menu.
5. To return the EBL origin to the own ship position, press the [EBL OFFSET] key again.
