ALTITUDE ALERTING
The Altitude Alerting function provides the pilot with visual and aural alerts when approaching the Selected
Altitude. Whenever the Selected Altitude is changed, the Altitude Alerter is reset. The Altitude Alerter is
independent of the GFC 700 AFCS, but alerting tones are generated only when the GFC 700 is installed. The
following occur when approaching the Selected Altitude:
• Upon passing through 1000 feet of the Selected Altitude, the Selected Altitude (shown above the Altimeter)
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 ft 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 pilot flies outside the deviation band (±200 feet of the Selected
Altitude), the Selected Altitude changes to yellow text on a black background, flashes for 5 seconds, and an
aural tone is generated.

LOW ALTITUDE ANNUNCIATION (WAAS ONLY)
NOTE: The Low Altitude Annunciation is available only for aircraft with GIA 63W Integrated Avionics Units
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.
