ALTITUDE ALERTING
The Altitude Alerting function provides visual and audio alerts when approaching the Selected Altitude.
Whenever the Selected Altitude is changed, Altitude Alerting 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.

Pilot-side PFD Selected
Copilot-side PFD Selected
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 five 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 five 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 five seconds,
and an aural tone is generated.

LOW ALTITUDE ANNUNCIATION
NOTE: This 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.
