TRIAL
MANEUVERING
Aftention
ln
lrial
maneuvering,
a simulation
is executed
with
the curent
course and speed
of the target
ship.
Since the situation
is different from actual
ship
maneuvers, the
CPA LIMIT and
TCPA LIMIT should
be
set with ample leeway.
Trial
maneuvering
is used to simulate
the
course
and
speed necessary
to avoid
a
collision
when a dangerous
target
appears.
When
the ship's
course
and speed are manually
entered
against
the data
of the acquired target,
a check is
made to determine
whether
there
is any danger.
The ranges of
course and speed
to be
entered manually are as
follows:
Course:
360 degrees
(0.1
degree
intervals)..................
[EBL]
control
Speed:
0
to 100
knols
(0.1
knot steps)......

Trial
Maneuvering
in the True
Vector
Mode
In the True
Vector
mode, calculations
are made according
to the
values set
by
TRIAL
SPEED
and TRIAL COURSE,
and
the
result is displayed
as
a
boldJine
that represents the
change
of
the own ship's vector as
shown
in the
figure
below
(an
example
of the course
changed
to
starboard).
In this
figure, the
dangerous target that
is ahead
to the
port
side becomes
safe
as a
result of
the simulation.
The target data
display
field indicates
the cunent CPA LIMIT
and
TCPA LIMIT values
regardless
of the
result of the simulation.
