PREFACE
Applicable to: ALL
This chapter deals with some characteristics of the Non Precision Approach (NPA).
Recommendations mentioned Refer to NO-100 preface.NPA are defined as:
• VOR approach
• NDB approach
• LOC, LOC-BC approach
• R-NAV approach.
APPROACH STRATEGY
Applicable to: ALL
The overall strategy of NPA completion is to fly it "ILS alike" with the same mental image or
representation and similar procedure. Instead of being referred to an ILS beam, the AP/FD guidance
modes and associated monitoring data are referred to the FMS F-PLN consolidated by raw data.
LOC only approach is the exception where LOC mode and localizer scale are to be used. This
explains why the crew must ensure that the FMS data is correct, e.g. FMS accuracy, F-PLN (lateral
and vertical) and proper leg sequencing.
The use of AP is recommended for all non-precision approaches as it reduces crew workload and
facilitates monitoring the procedure and flight path.
LIMITATIONS
Applicable to: ALL
Lateral and vertical managed guidance (FINAL APP) can be used provided the following conditions
are met:
• The approach is defined in the navigation database
• The approach has been crosschecked by the crew with the published procedure
• The final approach is not modified by the crew.
INITIAL APPROACH
Applicable to: ALL
NAVIGATION ACCURACY
The navigation accuracy check is most essential since it determines
• The AP/FD guidance mode to be used
• The ND display mode to be used
• Which raw data which are to be used.

(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 during a
managed non-precision approach, the crew should proceed as follow:
Message VOR, ADF, VOR/DME approach GPS approach
GPS PRIMARY LOST Interrupt the approach
NAV ACCY DNGRADED Cross-check the navigation accuracy:
If positive, continue managed
approach
If negative, revert to selected
approach with raw data.

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 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
