NOTE
FLTA Disabled in External TAWS Equipped Aircraft
In order to prevent possibly conflicting alerting
information, when an external TAWS/EGPWS system in
installed in the airplane as determined by the "External
TAWS" field selection on the "Main System Config"
page at time of installation, all FLTA functionality is
turned off, including the "FLTA Off" and "FLTA Inhibited"
CAS messages in Release 10.1.1.0 or later.
Should an FLTA alert be generated, there are several courses of
action that can be taken and the specific scenario will dictate the
optimum avoidance maneuver. For example, sometimes the best
course of action is to immediately add power and climb, yet
sometimes the best course of action may be a small heading change,
especially in the case of a single obstacle off the nose. The pilot in
command must assess the specific circumstances presented and
take action to avoid flight into terrain.

500' CALLOUT

A 500' aural alert is played anytime the aircraft descends through
500' AGL as calculated by comparing GPS MSL altitude with terrain
database elevation data immediately below the aircraft. This feature
is primarily intended to provide situational awareness to the pilot
when the airplane is being operated properly per normal procedures.
Therefore, it is not suppressed in FLTA exclusion areas, however, it
will not play while there is an active FLTA caution or warning.
In aircraft that have this feature enabled, it can be optionally turned
on/off via the User Options page.
In TAWS equipped aircraft, this feature is not de-selectable.
