? The decelerated approach
? The stabilized approach
THE DECELERATED APPROACH
This technique refers to an approach where the aircraft reaches 1 000 ft in the landing
configuration at VAPP. In most cases, this equates to the aircraft being in CONF 1 and at S speed at the FAF. This is the preferred technique for an ILS approach. The deceleration pseudo-waypoint assumes a decelerated approach technique.
THE STABILIZED APPROACH
This technique refers to an approach where the aircraft reaches the FAF in the landing configuration at VAPP. This technique is recommended for non-precision approaches. To get a valuable deceleration pseudo waypoint and to ensure a timely deceleration, the pilot should enter VAPP as a speed constraint at the FAF.
STABILIZED VERSUS DECELERATED APPROACH
 
F-PLN SEQUENCING
When in NAV mode, the F-PLN will sequence automatically. In HDG/TRK mode, the F-PLN waypoints will sequence automatically only if the aircraft flies close to the programmed route. Correct F-PLN sequencing is important to ensure that the programmed missed approach route is available in case of go-around and to ensure correct predictions. A good cue to monitor the proper F-PLN sequencing is the TO waypoint on the upper right side of the ND, which should remain meaningful.

FLIGHT CREW TRAINING MANUAL 

If under radar vectors and automatic waypoint sequencing does not occur, the F-PLN will be sequenced by either using the DIR TO RADIAL IN function or by deleting the FROM WPT on the
F-PLN page until the next likely WPT to be over flown is displayed as the TO WPT on the ND.
INITIAL APPROACH
Criteria: P7373, P7519, P7666, SA
2 Applicable to: MSN 1668-4078
NAVIGATION ACCURACY
Prior to any approach, a navigation accuracy check is to be carried out. On aircraft equipped with
GPS however, no navigation accuracy check is required as long as GPS PRIMARY is available. Without GPS PRIMARY or if no GPS is installed, navigation accuracy check has to be carried out. The navigation accuracy determines which AP modes the crew should use and the type of display to be shown on the ND.
THE FLYING REFERENCE
It is recommended to use the FD bars for ILS approaches and the FPV called "bird" with FPD for non-precision or circling approach approaches.
APPROACH PHASE ACTIVATION
Activation of the approach phase will initiate a deceleration towards VAPP or the speed constraint inserted at FAF, whichever applies.
When in NAV mode with managed speed, the approach phase activates automatically when sequencing the deceleration pseudo-waypoint. If an early deceleration is required, the approach phase can be activated on the MCDU PERF APPR page. When the approach phase is activated, the magenta target speed becomes VAPP.
When in HDG mode, e.g. for radar vectoring, the crew will activate the approach phase manually.
