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.

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
