Before reaching the FAF (or the Final Descent Point, if different):
.  
Align the aircraft (within 5 degree) with the final approach course;

.  
Select the landing gear down;

.  
Arm the ground spoilers;

.  
Set landing flaps;

.  
Set and establish the final approach speed;

.  
Set the GA altitude (if the GA altitude is the same as the FAF crossing altitude, set the GA altitude only after initiating the final descent);

.  
Perform the LANDING checklist;

.  
If use of FMS vertical navigation is not authorized beyond the FAF, deselect the FMS vertical navigation mode by selecting the altitude hold or the vertical speed mode, as required;

.  
If V/S mode will be used after the FAF, set the published or computed vertical speed and course; and/or,

.  
If flight path vector (FPV, as available) will be used after the FAF set the published or computed flight path angle (FPA) and track.

Approaching the FAF or the Final Descent Fix (FDF)
Typically 0.3 nm to 0.2 nm before reaching the FAF / FDF (i.e., to begin the descent at the FAF / FDF, on an accurate profile):
.  
Engage the V/S mode and check V/S mode engagement on FMA;

.  
Set the published (or computed) vertical speed, as a function of the ground speed;

.  
Select FPV (as applicable);

.  
Start timing (as required); and,

.  
Crosscheck and announce the next fix (or DME distance, as applicable) and crossing altitude.


During the descent towards the MDA(H):
.  Monitor the vertical speed, flight path vector (as available), course, distances, altitudes and call out the published vertical profile at each safety altitude / distance check:
.  Check and announce the altitude deviation from charted crossing altitude;
.  Adjust the vertical speed, as required; and,
.  Call out the next fix (or DME distance) and the associated crossing altitude.

.  Set or confirm the go-around altitude on FCU.
At MDA(H) + 1/10 rate of descent (i.e., MDA(H) + 50 to 100 ft) :
.  If the approach has not been surveyed and/or if the operational authorities do not accept the MDA(H) as a DA(H), anticipate the go-around decision to prevent undershooting the MDA (H).

At MDA(H) / reaching the VDP :
.  
If adequate visual references are acquired :

.  Disconnect the AP and continue the approach visually (the autothrottle/autothrust should remain engaged in speed mode down to the retard point, as applicable).


.  
If adequate visual references are not acquired :


.  Initiate a go-around; and,
.  Overfly the MAP to ensure adequate obstacle clearance and fly the published missed-approach procedure (or follow ATC instructions).
