HYPOXIA RECOGNITION WITH AUTOMATIC DESCENT MODE (OPTIONAL)
NOTE: The Automatic Descent Mode does not account for terrain elevation.
The system is operative when the aircraft altitude is above 14,900 feet (pressure
altitude) and the Garmin AFCS autopilot is engaged. Pilot interaction with the
Perspective
system is monitored by detecting key presses and turns of the knobs
(Audio Panel and push-to-talk switch excluded). If a period of inactivity (time
dependent on altitude) is detected, Hypoxia Recognition initiates and automatic
descent.
When the system detects a sufficient period of inactivity the Advisory Annunciation
ARE YOU ALERT?’ is displayed. Selecting the ALERT Softkey will acknowledge the
message and reset the system. Pressing any other softkey, or turning a knob will also
reset the system.
When no pilot interaction is detected for an additional 60 seconds, the Caution
Annunciation ‘HYPOXIA ALERT’ is displayed. Again, selecting the ALERT Softkey
will acknowledge the message and reset the system. Pressing any other softkey, or
turning a knob will also reset the system.
When no pilot interaction is detected for an additional 60 seconds, the Warning
Annunciation ‘AUTO DESCENT’ is displayed in the Annunciation Window and
‘Automatic descent to 14,000FT in 60 seconds’ is displayed in the Alerts Window.
Once again, selecting the ALERT Softkey will acknowledge the message and reset the
system. Pressing any other softkey, or turning a knob will also reset the system.
When no interaction is detected for another 60 seconds, the system will
automatically 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. ‘AUTO DESCENT - Aircraft Descending to 14,000FT’ is displayed in the
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.
