However,
it
is
important
to
note
that
C.A.T.
does
not
automatically
avoid
collisions
with
all
obstacles
in
all
conditions
and
circumstances.
Factors
including
the
material,
size
and
shape
of
an
obstacle/object,
its
position
and
angle
relative
to
the
sensor(s)
and
the
speed
the
helicopter
is
traveling
at
can
have
an
impact
on
detection
and
the
corresponding
response.
For
example
the
technology
will
best
detect
obstacles/objects
with
surfaces
made
from
materials
that
better
reflect
ultrasound
waves.
Such
obstacles/objects
can
include
some
walls,
uncovered
windows,
furniture
(cabinets,
bookcases,
desks,
etc.)
and
others.
Obstacles/objects
with
surfaces
made
from
materials
that
can
absorb
ultrasound
waves,
including
some
fabric
covered
furniture,
window
curtains/drapes
and
others,
will
be
more
difficult
to
detect.
One
potential
way
to
determine
how
well
a
particular
obstacle/object
can
be
detected
is
to
follow
the
test
procedure
outlined
in
the
‘C.A.T.
Testing’
section.
Other
factors
can
also
have
an
impact
on
detection
and
the
corresponding
response
of
the
technology.
Some
of
these
factors
can
include
the
obstacle’s/object’s
size
and
shape
as
well
as
its
position
and
angle
relative
to
the
sensor(s).
For
example
the
‘smaller’
the
surface
of
an
obstacle/object
is
relative
to
the
sensor(s)
the
less
likely
it
is
to
be
detected
unless
it’s
more
‘directly’
in
front
of
the
sensor(s)
.
Also,
the
sensors
will
typically
better
detect
an
obstacle/object
when
the
front
(the
side
with
the
‘mesh
screen’)
is
as
close
to
parallel
to
the
surface
of
the
obstacle/object
as
possible.
However,
the
sensors
can
still
detect
some
obstacles/objects
even
when
they
are
not
directly
in
front
of
and/or
no
surfaces
are
parallel
to
the
sensors,
albeit
at
limited/less
range.
Another
important
factor
to
consider
is
the
speed
at
which
the
helicopter
is
traveling
toward
an
obstacle/object.
The
faster
the
helicopter
is
moving
the
less
time
the
technology
will
have
to
detect
and
respond.
Even
when
an
obstacle/object
is
made
from
a
material
that
better
reflects
ultrasound
waves,
and
has
a
relatively
large
surface
that’s
positioned
directly
in
front
of
and
parallel
to
the
front
of
the
sensor
(such
as
a
wall),
if
the
helicopter
is
moving
toward
it
too
quickly
the
technology
may
not
be
able
to
detect
it
and
respond
in
time
to
help
prevent
a
collision.
It
is
typically
recommended
to
use
the
‘Low
(LO)’
control
rate
setting
on
the
transmitter
and/or
minimal
control
inputs
to
keep
the
helicopter
from
traveling
too
quickly
toward
obstacles/objects
whenever
possible.
Turning
C.A.T.
On
and
Off
The
advanced
C.A.T.
software
offers
selectable
modes
suitable
for
flying
in
larger
and
smaller
indoor
spaces
(see
the
‘HI
and
LO
Mode
Settings’
section
for
more
information)
and
also
makes
it
possible
to
turn
the
technology
on
and
off
remotely
from
the
transmitter
at
any
time.
When
using
the
MP5H
transmitter
included
with
the
RTF
version
the
‘GEAR’
(channel
5)
switch
located
on
the
top
left
‘shoulder’
will
turn
the
technology
on/off.
When
the
switch
is
in
the
‘0’
position
(toward
the
back
of
the
transmitter)
the
technology
will
be
OFF.
When
the
switch
is
in
the
‘1’
position
(toward
the
front
of
the
transmitter)
the
technology
will
be
ON
(as
indicated
by
the
blue
color
LED
that
will
illuminate
the
inside
of
the
case/housing
for
the
C.A.T.
module
any
time
the
technology
is
turned
ON).
