For CATII or CATIII ILS, the crew will insert DH into DH field on MCDU PERF APPR page, since this value is a radio altitude referenced.
INITIAL APPROACH
Applicable to: ALL
NAVIGATION ACCURACY
When GPS PRIMARY is available, no NAV ACCURACY monitoring is required. When GPS PRIMARY is lost the crew will check on MCDU PROG page that the required navigation accuracy is appropriate. If NAV ACCURACY DOWNGRAD is displayed, the crew will use raw data for navigation accuracy check. The navigation accuracy determines which AP modes the crew should use and the type of display to be shown on the ND.

FLYING REFERENCE
The crew will select HDG V/S on the FCU i.e. "bird" off. APPROACH PHASE ACTIVATION
For a standard ILS, the crew should plan a decelerated approach. However, if the G/S angle is greater than 3.5 ° or if forecast tail wind at landing exceeds 10 kt (if permitted by AFM), a stabilized approach is recommended.
If FAF is at or below 2 000 ft AGL and if deceleration is carried out using selected speed, the crew should plan a deceleration in order to be able to select conf 2 one dot below the G/S.
 
NORMAL OPERATIONS
ILS APPROACH
 
MISCELLANEOUS
The LS PB is to be checked pressed in the first stage of the approach.
The crew will check that:
? LOC and GS scales and deviations are displayed on PFD
? IDENT is properly displayed on the PFD. If no or wrong ident displayed, the crew will check the audio ident.
INTERMEDIATE APPROACH
Applicable to: ALL
INTERCEPTION OF FINAL APPROACH
When cleared for the ILS, the APPR pb should be pressed. This arms the approach mode and LOC and GS are displayed in blue on the FMA. At this stage the second AP, if available, should be selected.
If the ATC clears for a LOC capture only, the crew will press LOC p/b on the FCU.
If the ATC clears for approach at a significant distance, e.g. 30 nm, the crew should be aware that the G/S may be perturbed and CAT 1 will be displayed on FMA till a valid Radio Altimeter signal is received.
FINAL APPROACH
Applicable to: ALL
GLIDE SLOPE INTERCEPTION FROM ABOVE
The following procedure should only be applied when established on the localizer. There are a number of factors which might lead to a glide slope interception from above. In such a case, the crew must react without delay to ensure the aircraft is configured for landing before 1 000 ft AAL. In order to get the best rate of descent when cleared by ATC and below the limiting speeds, the crew should lower the landing gear and select CONF 2. Speedbrakes may also be used, noting the considerations detailed in the sub-section "Deceleration and configuration change" earlier in this chapter. The recommended target speed for this procedure is VFE 2 - 5 kt. When cleared to intercept the glide slope, the crew should:
