2.3.4.5 Enabling EBL/VRM FLOAT Using Cursor
Starting from your own position, the EBL is placed on a desired target, using
the cursor. The current coordinates can be displayed numerically to the right of
the toggle field (  ).
In this case the EBL/VRM 1 and 2 comes up with the default navigators settings
(factory settings for ALIGNMENT are NORTH STABILIZED and for BASE
POINT POSITION FIXED). It is possible to change these factory settings via
service tool for ALIGNMENT to OWNSHIP STABILIZED and for BASE POINT
to OWNSHIP FIXED.
In the EBL/VRM menu the navigator opportunities for EBL/VRM 3 and 4 can be
switched over between POSITION FIXED and OWNSHIP FIXED (BASE
POINT), OWNSHIP STABILIZED and NORTH STABILIZED (ALIGNMENT).
These settings have to be done before editing EBL/VRM 3 and 4.
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 relation to geographic 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
center 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.
