5.3 Toolset1 and 2
Each toolset offers the use of one variable range marker (VRM)
and one electronic bearing line (EBL).
With the aid of the EBL and VRM bearings and distances
between an object and the own ship or bearings and distances
between two objects can be determined.
☞ When measuring bearing and distance between the own
ship and an object, the current setting of the CCRP must
be considered: The CCRP set to RADAR gives measure-
ments relative to the selected radar antenna, and CCRP
set to Conning gives values relative to the conning posi-
tion on the bridge, as long as EBL and VRM are operated
in centered mode. See chapter 2.1 on page III-16.
Using the dropdown-list beneath T, it can be chosen wether
the bearing is to be displayed as true bearing (T) or relative
bearing (REL). When the pointer is moved upon the dropdown
list, a windows appears showing the true and relative bearing
of the recent VRM.
Additionally, Move can be chosen if the origin of the bearing
line is to move together with the own ship, Fixed can be
selected if the origin is to remain at an absolute position on the
screen.
5.3.1 EBL
With the EBL, the bearing of an object with
respect to own ship or the bearing
between two objects can be determined.
After switch-on by means of a click in the
Toolset group, the EBL are superimposed
in the PPI. EBL appear with the same data
as they have been displayed last time.
In order to alter the bearing of the EBL,
click on it in the PPI. The EBL is now
displayed with a small "handle" in its
middle. Click and hold the handle and pull
the line to the desired bearing.
In order to change the origin of the
bearing line, click and pull its origin to the
desired position.
Switch the EBL off and on again in order
to re-center it on the own ship.
