4.2.3.4. Altitude Level-O and Deviation Alert
The Altitude (level-o ) Alert is ARMED and rendered on-screen as a yellow alert ag
next to the Selected Altitude value when the aircraft altitude transitions to within
200 feet or 15 seconds of reaching the selected altitude (Figure 4-23). If an optional
Sonalert tone generator device is installed, a one-second tone also sounds. Once
the current altitude is within ± 25 feet of the Selected Altitude, the Altitude Alert
extinguishes (Figure 4-24).
After reaching the Selected Altitude, if the aircraft’s current altitude diers from the
selected altitude by more than 200 feet, the yellow alert ag ashes. If an optional
Sonalert tone generator device is installed, a one-second tone also sounds.

NOTE
Setting the Altitude Alerter provides visual cues to help the pilot capture and maintain target
altitudes. When set to a new altitude, the Alerter will illuminate a yellow ag adjacent to
the target altitude display; 15 seconds (or 200 feet) before the aircraft will reach the target
altitude (based on current rate of climb or descent). The yellow ag will extinguish once the
target is reached. Subsequently, if the aircraft deviates more than 200 feet above or below
the target altitude, the ag will again illuminate to thedeviation.
