FLYING REFERENCE
The "bird" is to be used as the flying reference APPROACH PHASE ACTIVATION
The stabilized approach technique is recommended. The crew will set VAPP as a speed constraint at FAF in order to get a meaningful deceleration pseudo waypoint.
INTERMEDIATE APPROACH
Applicable to: ALL
INTERCEPTION OF FINAL APPROACH COURSE
It is essential to have a correct F-PLN in order to ensure proper final approach guidance. Indeed the NAV and APPR NAV modes are always guiding the aircraft along the F-PLN active leg and the managed vertical mode ensures VDEV =0, VDEV, being computed along the remaining F-PLN to destination. Hence, the crew will monitor the proper sequencing of the F-PLN, more specifically if
NORMAL OPERATIONS
NON PRECISION APPROACH
HDG mode is selected, by checking that the TO WPT, on upper right hand corner of ND, is the most probable one and meaningful.
F-PLN sequencing in approach
If ATC gives radar vectors for final approach course interception, the crew will use DIR TO FAF with RADIAL INBND facility. This creates an ILS alike beam which will be intercepted by NAV and APPR NAV modes. Additionally, the VDEV is realistic, XTK is related to the beam and the ND gives a comprehensive display.
F-PLN sequencing in approach
When cleared for final approach course interception, the pilot will either:
? Press APPR p/b on FCU if managed approach. On the FMA, APP NAV becomes active and FINAL becomes armed. The VDEV or "brick" scale becomes active and represents the vertical deviation, which may include a level segment. The VDEV/brick scale will only be displayed if LS pb is not pressed. If the LS pb is pressed by mistake, the V/DEV will flash in amber on the PFD or
? Select adequate TRK on FCU, if selected approach, in order to establish final course tracking with reference to raw data. When established on the final course, the selected track will compensate for drift.
The final approach course interception will be monitored through applicable raw data.
FINAL APPROACH
Applicable to: ALL
It is essential that the crew does not modify the final approach in the MCDU FPLN page.
NORMAL OPERATIONS
NON PRECISION APPROACH
The final approach will be flown either:
? Managed or
? Selected
MANAGED
For a managed approach, FINAL APP becomes active and the FM manages both lateral and vertical guidance.
The crew will monitor the final approach using:
? Start of descent blue symbol on ND
? FMA on PFD
? VDEV, XTK, F-PLN on ND with GPS PRIMARY
? VDEV, XTK, F-PLN confirmed by needles, distance/altitude
If FINAL APPR does not engage at start of descent, the crew will select FPA convergent to the final path so as to fly with VDEV=0. Once VDEV=0, the crew may try to re-engage APPR.
