2.3.4.1 Enabling EBL / VRM OFFSET using cursor
The electronic bearing line EBL is used for the bearing.
Starting from your own position, the EBL is placed on a desired target, e.g. using
the cursor. The current co
− ordinates are displayed numerically to the right of the
toggle field ( _ ).
The numerical display is normally displaying as true information when the GYRO
sensor is available. If the GYRO sensor is not available the numerical display
changes automatically to relative information.
T(rue) shows the numerical bearing value to the target as a true value
(in terms of North).
R(elative) shows the numerical bearing to the target as a relative value
(relative to ship heading).
The variable range marker VRM is used to mark a particular range circle.
The zone can be your own position or the EBL1 root point, for example. The
current radius is displayed to the right of the toggle field (NM).
Electronic bearing lines EBL and variable range markers VRM can be used
jointly as a group.
Identification of the EBL and VRM representation
The dotted EBL is drawn from your own ship through the cursor symbol.
Place the cursor on a selected target and press the
Left button on the trackball.
The dotted VRM is extended from your own ship by moving the cursor symbol.
