TERRAIN

Both Terrain Awareness (TA) and Forward Looking Terrain Alerting
(FLTA) are meant to serve as an aid to situational awareness. They
are intended to provide terrain and obstacle awareness in the
proximity of your aircraft. They are not meant to be the sole means of
terrain or obstacle avoidance.
Both TA and FLTA use a GPS-based MSL altitude and a 9 arc-
second terrain database (WGS-84) to display a two dimensional
scene representing an "exocentric" look-down-from-above view. The
database is loaded on the AeroNav prior to shipping from the factory,
and is capable of being updated in the same manner as other
onboard databases, if necessary.
Both TA and FLTA compute height above terrain via GPS inputs and
are not a radio altimeter (RADALT).
