Applicable to:
L2 Rely on the CAB PR EXCESS CAB ALT warning even if not confirmed on the CAB PRESS SD
page. The warning can be triggered by a cabin pressure sensor different from the one used to
control the pressure and display the cabin altitude on the SD.
L1CREW OXY MASK (IF ABOVE FL100)......................................................................................... ON
DESCENT............................................................................................................................ INITIATE
EMER DESCENT FL 100/MEA (OR MINIMUM OBSTACLE CLEARANCE ALTITUDE)
THR LEVERS (IF A/THR NOT ENGAGED)................................................................................ IDLE
SPD BRK................................................................................................................................... FULL
L2 Extension of speedbrakes will significantly increase VLS.
In order to avoid autopilot disconnection and automatic retraction of speedbrakes due to possible
activation of angle of attack protection, allow the speed to increase before starting to use
speedbrakes.
L1 SPD.................................................................................................................... MAX/APPROPRIATE
L2 Descend at maximum appropriate speed. However, if structural damage is suspected use the
flight controls with care and reduce speed as appropriate. Landing gear may be extended below
25 000 ft. In this case, speed must be reduced to VLO/VLE.
L1 SIGNS............................................................................................................................................ON
ENG MODE..................................................................................................................................IGN
ATC........................................................................................................................................NOTIFY
L2Notify ATC of the nature of the emergency and state the intentions.
If ATC cannot be contacted, select ATC code A7700 or transmit a distress message on one of the
following frequencies:
(VHF) 121.5 MHz, or (HF) 2.182 kHz, or 8 364 kHz.
To save oxygen, set the oxygen diluter selector to N position.
With the oxygen diluter left to 100 %, oxygen quantity may not be sufficient for the entire descent
profile.
Ensure that the flight crew can communicate wearing oxygen masks. Avoid the continuous use of
the interphone position to minimize the interference from the noise of the oxygen mask.
L1 IF CAB ALT > 14 000 FT:
PAX OXY MASKS...........................................................................................................MAN ON
L2Contact the cabin crew to confirm that the passenger oxygen masks are released.
