In some NPAs, the final approach flies an "idle descent" segment from one altitude constraint to another, followed by a level segment. This is materialized by a magenta level off symbol on ND followed by a blue start of descent.
final approach trajectory with idle descent segment
SELECTED
For a selected approach, the Final Path Angle (FPA) should be preset on the FCU 1 N.m prior to the
FAF at the latest. A smooth interception of the final approach path can be achieved by pulling the FPA selector 0.2 N.m prior to the FAF.
If GPS is PRIMARY, the crew will monitor VDEV, XTK and F-PLN. Additionally, for VOR or ADF approaches, the crew will monitor raw data.
NORMAL OPERATIONS
NON PRECISION APPROACH
REACHING THE MINIMA
Applicable to: ALL
When approaching MDA, the pilot flying should expand the instrument scan to include outside visual cues.
Reaching MDA, "MINIMUM" is either monitored or called by the crew. The current altitude value becomes amber
? If the required conditions are not met by MDA, a missed approach must be initiated.
? If the required visual conditions are met to continue the approach, the AP must be disconnected, the FDs selected off, Bird ON and continue for visual approach.
LOC ONLY APPROACH
Applicable to: ALL
LOC ONLY approaches may be flown using the LOC signal for lateral navigation and FPA for vertical guidance. General recommendations mentioned above still apply. i.e. stabilized approach technique, use of the bird. Some additional recommendations need to be highlighted.
INITIAL APPROACH
The crew will select LS p/b on the EIS control panel. INTERMEDIATE APPROACH
The crew will press LOC p/b on the FCU when cleared to intercept. He will monitor the LOC armed mode and then LOC capture.
FINAL APPROACH
Approaching FAF, the crew will select FPA. When established on the final path, the crew will monitor:
? Lateral displacement with LOC deviation
? Vertical displacement with DME and ALT, "yoyo", time
LOC BACK COURSE APPROACH
Applicable to: ALL
LOC-BC approaches may be flown using the Bird with reference to the LOC-BC signal for lateral guidance and FPA for vertical guidance. General recommendations mentioned above still apply i.e. stabilized approach technique and use of the bird. Some additional recommendations need to be highlighted.
NORMAL OPERATIONS
NON PRECISION APPROACH
GENERAL
The LOC-BC approach consists in using the LOC signal of the opposite runway for lateral approach management.
If the LOC-BC approach is stored in the FMS data base, it will be inserted into the F-PLN. The ILS frequency and associated back course are automatically tuned and displayed on the MCDU RAD NAV page. The CRS digit will be preceded by a "B".
If LOC-BC is not stored in the FMS data base, the crew will enter the ILS frequency and the final approach CRS the aircraft will actually fly preceded by a "B" in MCDU RAD NAV page. B/C in magenta will be displayed both on PFD and ND. This provides a proper directional deviation on PFD and a proper directional guidance from the FG.
