2.4.2 Altitude Alerting
The Altitude Alerting function provides the pilot with visual and aural
alerts (if interfaced to an audio panel) when approaching the Selected Altitude.
Whenever the Selected Altitude is changed, the Altitude Alerter is reset. The
Altitude Alerter is independent of any autopilot installed in the aircraft. 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 five seconds.
•Whentheaircraftpasseswithin200feetoftheSelectedAltitude,theSelected

an aural tone is generated.
