DIS PLAY FA CIL ITIES
17
For information on how to select any facility on the
display, refer to Chapter 1 - Operating Information.
Range Scales
18
The PPI range scales are: 0.125nm, 0.25nm, 0.5nm,
0.75nm, 1.5nm, 3nm, 6nm, 12nm, 24nm, 48nm and
96nm.
Screen Modes of Op er a tion
19
The following modes of operation and presentation are
available for selection, depending on the type of
display installed:
(1) Relative Motion,
Relative Trails RM(R)
(2) True Motion,
True Trails TM(T)
(3) Relative Motion,
True Trails RM(T)
(4) Head Up.
(5) North Up.
(6) Course Up.
Op tions (True Mo tion and Rel a tive Mo tion with True
Trails)
20
True Motion (True Trails), TM(T) is available - where
Ownship moves across the screen at a velocity
equivalent to the Ownship’s speed and heading.
21
Relative Motion (True Trails) mode offers relative
motion, fixed centred or off-centred Ownship’s
position, with true trails.
Offcentre
22
The display can be offcentred by up to 70%, on all
range scales, except 96nm.
Head ing Line
23
The ship’s heading line and all other computer
generated graphics can be temporarily removed from
the radar display, to present the operator with a clear radar
only picture.
Vari able Range Marker
24
The Variable Range Markers (VRM1 & VRM2) are
shown on the radar display as dashed rings (colour
coded; Green for VRM1 and Red for VRM2) and are
available over the entire radar range. The VRMs ranges are
displayed by an alphanumeric readout in a box (colour
coded; Green for VRM1 and Red for VRM2), located in the
lower left-hand side of the screen.
Elec tronic Bear ing Line
25
The Electronic Bearing Lines (EBL1 & EBL2) are
shown on the radar display as lines colour coded;
(Green for EBL1 and Red for EBL2), emanating from
Ownship. The EBLs are True in North Up display mode and
Relative in Head Up mode. The bearings of the EBLs are
displayed as an alphanumeric readout in a box (colour
coded; Green for EBL1 and Red for EBL2), located beneath
the VRM box.
26
The EBL can be off-centred and the origin set to the
cursor position. This enables measurement of the
bearing of a target from a point other than the Ownship.
Sig nal Con trols - Gain, Sea, Rain
27
The Gain facility sets the basic threshold level of the
radar video displayed on the screen. The Sea facility
reduces sea clutter returns and features an "AUTO"
(automatic) option. The Rain facility reduces clutter from
rain, snow and hail precipitation.
Ownship and Plotting Pa ram e ters
28
Ownship and Plotting parameters are displayed in a
box (located on the right-hand side of the screen)
which contains Gyro, Heading, Speed, Set & Drift Input,
Vector, Trails, CPA and TCPA.
Tar get Data
29
Target data is displayed on demand, for any selected
tracked target, in a box located beneath the Ownship
and Plotting parameter data box.
Par al lel In dex Lines
30
Four colour-coded Parallel Index Lines are provided
to enable the operator to navigate in difficult areas
(e.g. an estuary). Each line is independent.
