Trial
Maneuvering in
the Relative Vector
Mode
The result
of
trial maneuvering
in
the
Relative
Vector
mode is shown
by
a change in
target
vector. ln
the
figure
below
(with
the same conditions
as in the True Vector mode on
the
previous page),
it is
seen that the
acquired
target is
a dangerous one because its vector
is
crossing
the
CPA
RING.
NORMAL
TRIAL
Change
in course
The above figure shows
that the relative
vector
ofthe
target has
changed as shown
in
the
figure
as a
result of simulation
(course
and speed), so
that the target's symbol is
changed
to
"o";
i.e.,
a safe
target.
As was the
case
in
lhe
True
Vector
mode, the data display
field
indicates the current
values of CPA LIMIT and TCPA
LlMlT, not
those as the result
of
the
simulation.
The course change of
own ship is displayed
as a dotted
line.
