4.2.3.4. Altitude Level-Off and Deviation Alert

The Altitude (level-off ) Alert is ARMED and rendered on-screen as a yellow alert flag
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 differs from the
selected altitude by more than 200 feet, the yellow alert flag flashes. 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 flag 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 flag will extinguish once the
target is reached. Subsequently, if the aircraft deviates more than 200 feet above or below
the target altitude, the flag will again illuminate to the deviation.
