Automatic Activation

If the aircraft experiences decompression and cabin altitude increases beyond the
threshold configured for the aircraft, the system automatically triggers EDM.
Warning and timer indications are identical to those
appearing on the Emergency page of the host
GDU TXi.
Status messages inform you of mode status.

You can activate EDM one of two ways:
From the Home page:
Tap Emergency > Emergency Descent.
From a dedicated external switch:
Enable the dedicated switch (if configured).
Upon Activation
The status window displays a
warning message and timer.
Emergency descent occurs once
the timer expires. This delay can
range from 10 to 60 seconds.
If manually activated, you may
skip the delay and activate EDM
immediately by selecting
Emergency Descent again.
