(1) For VOR approach, one pilot may select ROSE VOR
(2) For LOC approach, select ROSE ILS
(3) The managed vertical guidance can be used provided the approach coding in the navigation database has been validated.
Should a NAV ACCY DNGRADED or a GPS PRIMARY LOST message is displayed before a managed non-precision approach, the crew should proceed as follow:
Message VOR, ADF, VOR/DME approach GPS approach
GPS PRIMARY LOST Cross-check the navigation accuracy:
If positive, continue
managed approach (1)
If negative, revert to selected
approach with raw data. Interrupt the approach
NAV ACCY DNGRADED -
(1) If HIGH accuracy is lost on one FMGC, the approach can be continued with the AP/FD associated to the other FMGC. 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.

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 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 sequence in approach
When ATC gives radar vector and clears for final approach course interception, the crew will: ‐ For managed approach
? Select HDG according to ATC
? Select APPR p/b on FCU
? Check on FMA the final approach mode engagement
If the green solid line intercepts the F-PLN active leg (1), this creates an INTERCPT point with final approach axis. APP NAV will engage when intercepting the final approach course.
If the green solid line intercepts the PRE NAV engagement path (2), APP NAV engages when intercepting the final approach course. The PRE NAV engagement path is at least 1 nm and may be longer depending on aircraft speed.
