ALTITUDE ALERTING
Altitude Alerting provides the pilot with a visual alert 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 heard only when the GFC 700 is installed. The following occur when approaching
the Selected Altitude:

LOW ALTITUDE ANNUNCIATION
NOTE: A Low Altitude Annunciation is available only when WAAS is available. This annunciation is not
shown for systems equipped 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.
