LOW ALTITUDE ANNUNCIATION
NOTE:
A Low Altitude Annunciation is available only when SBAS is available. If the aircraft has the Terrain-
SVT feature, the ‘LOW ALT’ annunciation is not applicable unless these features are inhibited, have failed, or
are unavailable.
When the Final Approach Fix (FAF) is the active waypoint in a GPS approach using SBAS vertical guidance,
a Low Altitude Annunciation may appear if the current aircraft altitude is at least 164 feet below the prescribed
altitude at the FAF. A black-on-amber ‘LOW ALT’ annunciation appears to the top left of the Selected Altitude,
flashes for several seconds, then remains displayed until the condition is resolved.

MINIMUM ALTITUDE ALERTING
For altitude awareness, a minimum altitude can be set in the REFERENCES Window. This can be based
on barometric altitude or temperature compensated barometric altitude. When active, the altitude setting is
displayed to the bottom left of the Altimeter. Once the altitude is within the range of the tape, a bug appears
at the reference altitude on the Altimeter. The following visual annunciations occur when approaching the
selected minimum altitude:
-
When the aircraft altitude descends to within 2500 feet of the minimum altitude, a box labeled ‘BARO MIN’
or ‘COMP MIN’ (based on the Selected Altitude source) appears with the altitude in cyan text (or magenta
for TEMP COMP). The bug appears in cyan (or magenta for TEMP COMP) on the altitude tape at the
corresponding altitude once in range.
-
When the aircraft passes through 100 feet of the Selected Altitude, the bug and text become white.
-
Once the aircraft reaches the Selected Altitude, the bug and text appear amber and the voice alert, “Minimums
Minimums”, is generated.
