Altitude Alerting; Low Altitude Annunciation - Garmin G1000:Socata Pilot's Manual

FLIGHT INSTRUMENTS

ALTITUDE ALERTING

The Altitude Alerting function provides visual and audio alerts when approaching the Selected Altitude.
Whenever the Selected Altitude is changed, the Altitude Alerter is reset. Altitude Alerting is based on the
altitude information shown on the PFD selected with the XFR Key on the AFCS Control Unit. Altitude Alerting
is independent of the AFCS.
The following occur when approaching the Selected Altitude:
• Upon passing through 1000 feet of the Selected Altitude, the Selected Altitude Box changes to black text on
a light blue background, flashes for 5 seconds, and an aural tone is generated.
• When the aircraft passes within 200 feet of the Selected Altitude, the Selected Altitude changes to light blue
text on a black background and flashes for 5 seconds.
• After reaching the Selected Altitude, if the aircraft flies outside the deviation band (±200 feet of the Selected
Altitude), the Selected Altitude Box changes to yellow text on a black background, flashes for 5 seconds, and
an aural tone is generated.

LOW ALTITUDE ANNUNCIATION

This Low Altitude Annunciation is available only for aircraft with GIA 63W Integrated Avionics Units
NOTE:
when WAAS is available. This annunciation is not shown for systems with TAWS, unless TAWS is inhibited.
When the Final Approach Fix (FAF) is the active waypoint in a GPS WAAS approach using 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-yellow 'LOW ALT' annunciation appears to the top right of the Altimeter,
flashing for several seconds then remaining displayed until the condition is resolved.
