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.
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.
Altitude Audio Callout
When the aircraft altitude transitions to within 200 feet or 15 seconds of reaching
the selected altitude, the audio alert sounds the voice message “ALTITUDE”.
After reaching the Selected Altitude, if the aircraft’s current altitude differs from
the selected altitude by more than 200 feet, the audio alert sounds the voice
