Before starting the approach, check that GPS PRIMARY is available on both MCDUs.

If the GPS PRIMARY LOST indication appears on the ND during the approach, discontinue
the approach, unless:
GPS is not required and navigation accuracy is confirmed against ‐ the radio NAVAID raw
data, or
‐ For RNAV approach not requiring GPS, HIGH accuracy appears on the MCDU with the
appropriate RNP value.
‐ If GPS PRIMARY is lost on only one FMGC, the approach can be continued, using the
AP/FD associated to the other FMGC.
If the FM/GPS POS DISAGREE ECAM caution is triggered during the approach, discontinue
the approach.
If the FMS1/FMS2 POS DIFF message is triggered during the approach, discontinue the
approach, unless radio NAVAID raw data is available and indicates correct navigation to
continue the approach by using the AP/FD associated to the non-affected FMGC side.
For RNAV approach WITHOUT GPS PRIMARY
Before starting the approach, check the FM position accuracy with radio NAVAID raw data.
Check, in addition, that HIGH accuracy appears on the MCDU with the specified RNP value.
If HIGH accuracy is lost on one FMGC, the approach can be continued with the AP/FD
associated to the other FMGC.
If HIGH accuracy is lost on both FMGCs, discontinue the approach.
If the FMS1/FMS2 POS DIFF message is triggered during the approach, discontinue the
approach, unless radio NAVAID raw data is available and indicates correct navigation to
continue the approach by using the AP/FD associated to the non-affected FMGC side.

GUIDANCE FOR LOC NON PRECISION APPROACHES
The Standard Operating Procedure of this section can be used for flying LOC approaches,
provided the following approach guidance items are observed.
The FM NAV mode can be used down to LOC interception.
For LOC intermediate and final approach, use the LOC AP/FD mode for lateral navigation,
associated with the FPA (or V/S) for vertical navigation.
Vertical navigation must be monitored using raw data (altimeter, distance to the runway given by
radio-NAVAID).

GUIDANCE FOR LOC NON PRECISION APPROACHES
The Standard Operating Procedure of this section can be used for flying LOC or LOC B/C
approaches, provided the following approach guidance items are observed.
The FM NAV mode can be used down to LOC or LOC B/C interception.
For LOC or LOC B/C intermediate and final approach, use the LOC or LOC B/C AP/FD mode for
lateral navigation, associated with the FPA (or V/S) for vertical navigation.
Vertical navigation must be monitored using raw data (altimeter, distance to the runway given by
radio-NAVAID).
Applicable to: ALL
APPROACH SPEED TECHNIQUE
In all cases, the crew should use managed speed.
The standard speed technique is to make a stabilized approach using AP/FD and A/THR:
The aircraft intercepts the final descent path in landing configuration, and at VAPP. For this
purpose, the flight crew should insert VAPP as a speed constraint at the FAF.
If the operator adopts a decelerated approach technique and the crew uses managed guidance,
the aircraft should intercept the final descent path at S speed in CONF 1.
The objective is to be stabilized on the final descent path at VAPP in the landing configuration, at
1 000 ft above airfield elevation (in instrument conditions, or at 500 ft above airfield elevation in
visual conditions, after continuous deceleration on the final descent path).
To be stabilized, all of the following conditions must be achieved prior to, or upon reaching this
stabilization height:
The aircraft is on the correct ‐ lateral and vertical flight path
‐ The aircraft is in the desired landing configuration
‐ The thrust is stabilized, usually above idle, to maintain the target approach speed along the
desired final approach path
‐ No excessive flight parameter deviation.
If the aircraft is not stabilized on the approach path in landing configuration, at 1 000 ft above
airfield elevation in instrument conditions, or at 500 ft above airfield elevation in visual conditions,
or as restricted by Operator policy/regulations, the flight crew must initiate a go-around, unless
