1.35 How to Measure Range and Bearing Between
Two Targets
How to measure range and bearing from the [CURSOR] menu
This procedure uses EBL1 and VRM1 as an example and is written on the premise
that neither of the EBLs or VRMs is active.
1. Place the cursor on the EBL1 box, then left-click. EBL1 is now active.
2. Place the cursor inside the operational display area, then right-click to show the
[CURSOR] context menu.
3. Select [EBL OFFSET]. The cursor is displayed with a red surround, indicating that
the [EBL OFFSET] mode is now active.
4. With the cursor in the operational display area, left-click. EBL1 moves to the cur-
sor location.
5. Place the offset EBL on the target of interest (Target 1), then left-click.
6. Right-click to deactivate the [EBL OFFSET] mode. The red surround on the cursor
disappears.
7. Place the cursor on the [EBL1] box, then spin the scrollwheel until EBL1 intersects
the secondary target (Target 2 in the example figure).
8. Place the cursor on the [VRM1] box, then spin the scrollwheel until the range
marker on EBL1 aligns with Target 2. The readouts for EBL1 and VRM1, at the
bottom of the screen, indicate the bearing and range between the Target 1 and
Target 2.
9. You can repeat the same procedure on third and fourth targets (shown as “Target
3” and “Target 4” in the above example) by using EBL2 and VRM2.
Bearing is shown relative to own ship with suffix "R" or as a true bearing with suffix "T"
depending on EBL relative/true settings in the [EBL•VRM•CURSOR SET] menu.
