proceed with the descent.
As the system prepares for descent, the Selected Altitude is set to 14,000 and
the AFCS enters Indicated Airspeed (IAS) mode with the airspeed reference set to
the maximum allowable airspeed setting for the specific aircraft model. Refer to the
Flight Director Vertical Modes in the AFCS section. AFCS lateral mode settings are
not affected.
As the descent begins, an ‘AUTO DESCENT’ warning is displayed in the Annunciation
Window.‘AUTODESCENT-AircraftDescendingto14,000FT’isdisplayedinthe
Alerts Window. ‘EDM’ is shown as an AFCS Status Annunciation indicating the system
has entered Automatic Descent Mode. ‘EDM’ (Emergency Descent Mode) is the AFCS
mode that is activated when Hypoxia Recognition initiates an automatic descent.
A continuous repeating chime will be heard as long as Automatic Descent Mode is
active. After the descent begins, Automatic Descent Mode can only be canceled by
disconnecting the autopilot.
As the aircraft reaches 14,000 feet the system sets the AFCS to Altitude Hold
mode. The AFCS will also remain in Automatic Descent Mode as indicated by ‘EDM’
continuing to be displayed as an AFCS Status Annunciation. The system again begins
monitoring for pilot interaction.
If no pilot interaction is detected for four minutes, the system initiates the second
descent.Asthesystempreparesforthisdescent,theSelectedAltitudeissetto12,500
and the AFCS again enters IAS mode with the airspeed reference set to the maximum
allowable airspeed for the specific aircraft model.
As the descent begins, an ‘AUTO DESCENT’ warning is displayed in the
Annunciation Window. ‘AUTO DESCENT - Aircraft Descending to 12,500FT’ is
displayed in the Alerts Window. ‘EDM’ is shown as an AFCS Status Annunciation.
Also, the continuous repeating chime is heard.
