Low Altitude Annunciation
NOTE: The LOW ALT annunciation is only available
in G1000 systems configured with WAAS-capable
GPS. Also, the LOW ALT annunciation is not
available when the G1000 is configured with
TAWS (Terrain Awareness & Warning System),
unless TAWS is inhibited.
When the Final Approach Fix (FAF) is the active
waypoint in a GPS WAAS approach using vertical guidance,
a LOW ALT (Low Altitude) annunciation may appear if
the current aircraft altitude is at least 164 feet below the
prescribed altitude at the FAF. The annunciation initially
flashes. After a few seconds the flashing stops and the
annunciation is displayed as shown in Figure 2-10.
