I
switch to select
the Relative
Vector
mode.
The
relative
vector
does
not
represent
the true
motion of a target,
but
its relative
relation
with the own
ship. This
means that
a target
with
its
relative
vector
direcled at
the own ship
(passing
through the CPA LIMIT ring)
is
a
dangerous target.
In
the
Relative Vector mode, the CPA
LIMIT of
targets
can be seen at a
glance.

The true
vector
is
not displayed.

the TRUE/REL modes can
be used
in the following
way: The
TRUE
vector can
be
used
to know the true
aspect ofa
target,
and the REL
vector
can be used
to know
the
closest
point
of approach
(CPA)
of a target.
