DESCRIPTION & OPERATION
Multi-Function Display (continued)
Terrain Proximity
t--ToTIr-l
If
the
G1000 system
is
configured
to
use
the
optional
Terrain Awareness and
Warning
System
(TAWS), Terrain Proximity
will
not
be available
for
use,
G1000
Terrain Proximity
is
a
terrain
awareness system that increases
situational
awareness and
aids in preventing
controlled
flight
into terrain (CFIT).
It
is
similar
to
the
Terrain
Awareness and
Warning
System
(TAWS) but
does
not
comply
with rSo-c151b
certification
standards.
Terrain Proximity
does
not
provide
warning
annunciations or voice
alerts
but
it
does
provide color
indications
on
map displays when terrain and
obstacles are
within
a certain altitude threshold
from
the aircraft. Although
the terrain and obstacle
color
map displays
are the
same,
TAWS
uses a
more extensive
database and
more
sophisticated
algorithms
to
assess
aircraft
distance
from
terrain and
obstacles. The terrain and
obstacles
database
may not
contain
all
obstructions, so the information provided
should
be used
as
an
aid to situational
awareness and should
never be used
to navigate
or
maneuver around
terrain.
