To commence a managed approach, press the APPR pb. APP NAV is displayed in green on the FMA with FINAL in blue. The V/DEV scale becomes active and represents the vertical deviation from the managed descent profile, which may include a level segment. The V/DEV scale will only be displayed if the LS pb is not pressed. If the LS pb is pressed, V/DEV will flash in amber on the PFD.
If FINAL APP does not engage at the descent point, select an FPA value to allow convergence with the final approach path. When VDEV is indicating that the vertical profile has been reached (VDEV = 0), attempt to re-engage FINAL APP mode by pressing the APPR pb.
For a selected approach, use TRK mode to establish final course tracking with reference to raw data. When established on the final course, the selected track will compensate for drift.
Should ATC give vectors towards the FAF, the use of the "DIR TO RADIAL IN" function will provide a representation of the extended centreline and cross-track error on the ND.
DETAILED APPROACH SEQUENCE Managed Non-precision Approach
Fly the intermediate approach conventionally and configure the aircraft in a similar manner to an ILS.
Use the following technique:
.  
For RNAV and GPS approach, check both GPS in NAV mode on the GPS MONITOR page and GPS PRIMARY is displayed on both MCDUs. Check RNP has sequenced to the approach value (0.30/0.37 nm).

.  
Check that deceleration occurs at the decel pseudo-waypoint, or if not, activate the approach phase approx 10 nm prior to the FAF.

.  
Select TRK/FPA display, confirming that the FPV and the FPD are displayed on the PFD.

.  
Ensure LS is not selected.

.  
When cleared for the approach, press the APPR pb to arm APP NAV and FINAL. If previously in NAV, APP NAV engages immediately.

.  
Do not engage the second AP.

.  
Check that the FMGS computed descent point, represented as a blue arrow, is displayed on the ND. It may not necessarily coincide with the chart descent point because the FMGS attempts to compute a continuous final descent path.

 

A330/A340 6.50.9 Non-precision Approach
FCTM  REV 1 (6 JUN 05)
.  
V/DEV appears in approach phase with FINAL armed.

.  
Ensure raw data is correctly displayed.

.  
FINAL APP engages when the aircraft intercepts the vertical flight path.

.  
Set the go-around altitude.

.  
Use managed speed unless there are specific ATC requirements.

.  
Start the chrono at the FAF to check FAF to MAP time.

.  
Monitor the approach using FPV/FPD and VDEV on the PFD, XTK and F-PLN waypoints on the ND with GPS PRIMARY, and confirmed by navaids for VOR, NDB and overlay approaches. Cross-check altitudes and distances with those published on the approach chart.

Selected Non-precision Approach
Fly the intermediate approach conventionally and configure the aircraft in a similar manner to an ILS. The approach can be flown fully selected or if navigation accuracy allows, managed laterally and selected vertically.
Partially.Selected.Approach
For a partially selected approach, i.e. managed laterally and selected vertically, continue as for a managed non-precision approach with the following additional consideration:
.  Fly the final approach in NAV and FPA modes (LOC and FPA for LOC or LOC B/C approaches).
Fully.Selected.Approach
For a fully selected approach:
.  Fly the final approach in TRK/FPA modes.
Both.Partially.And.Fully.Selected.Approaches
For both partially and fully selected approaches, use the following technique:
.  
Check that deceleration occurs at the decel pseudo-waypoint, or if not, activate the approach phase approx 10 nm prior to the FAF.
