The procedures for an emergency descent are detailed on ECAM, in the QRH and in FCOM
3.02.80 (ABN and EMER procedures - EMER DESCENT).
The use of autopilot and autothrust is recommended for all emergency descents. The modes used will depend on whether structural damage is assumed or a high speed descent is required. The following are the two ways in which to use the autopilot and autothrust depending on which type of descent is required. As per standard ECAM procedures PF flies the aircraft and PNF carries out ECAM drill. However before initiating descent the crew must don oxygen masks and establish crew communications.
STRUCTURAL DAMAGE ASSUMED
.  
Turn altitude selector knob to MEA or FL 100 and pull

.  
Pull and turn heading selector knob

.  
Pull SPD selector knob

.  
Push speed/mach pb (target speed for descent is current IAS and may be adjusted as necessary)

.  
Check FMA reads IDLE | OP DES | HDG |

.  
Check target altitude and speed are as desired

.  
Select speedbrake (see note below)

HIGH SPEED DESCENT

.  
Turn altitude selector knob to MEA or FL 100 and pull

.  
A320 - Press EXPED mode engagement button
A319/321 pull speed knob and increase speed to MMO/VMO

.  
Pull and turn heading selector knob

.  
Check FMA reads IDLE | EXP DES | HDG | (A320 only)

.  
Check FMA reads IDLE | OP DES | HDG | (A319/321)
