or “Minimum” auto callouts which would not be applicable.
LANDING CATEGORIES
Applicable to: ALL
Each FMGC computes its own landing category : CAT1, CAT2, CAT3 single, and CAT3 dual and
displays the corresponding landing category on the FMAs.
Each category depends upon the availability of aircraft systems and functions.
When the landing category downgrades, a triple clic aural warning is activated.

FAIL-OPERATIONAL AUTOMATIC LANDING SYSTEM
An automatic landing system is fail-operational if, in the event of a failure below alert height, the
remaining part of the automatic system allows the aircraft to complete the approach, flare, and
landing. A CAT 3 DUAL system is a fail-operational automatic landing system.
Note: In the event of a failure, the automatic landing system operates as a fail-passive system.
FAIL-PASSIVE AUTOMATIC LANDING SYSTEM
An automatic landing system is fail-passive if, in the event of a failure, there is no significant
out-of-trim condition or deviation of flight path or attitude, but the landing is not completed
automatically. A CAT3 single system is a fail-passive automatic landing system.
Note: With a fail-passive automatic landing system the pilot assumes control of the aircraft after
a failure.
Below 100 ft (radio altimeter), the FMGS freezes the landing capability until LAND mode is
disengaged or both APs are off.
Therefore a failure occurring below 100 ft does not change the category of the system.
ALERT HEIGHT
The alert height is the height above touch down, above which a CAT3 autoland would be
discontinued and a missed approach executed, if a failure occurred in either the airplane systems
or the relevant ground equipments.
Below the alert height, if such a failure occurs, the flare, touchdown and roll out may be
accomplished using the remaining automatic system.
WARNINGS FOR ILS APPROACH
Applicable to:
AUTOLAND WARNING
With “LAND” or “FLARE” in green on the FMA and at least one AP engaged, the AUTOLAND
red light appears on the glareshield when the aircraft is below 200 ft RA and one of the following
events occurs :
‐ The autopilots are lost, or
The aircraft gets too far off the ‐ beam (LOC or G/S flash on PFD), or
‐ Loss of LOC signal above 15 ft, or loss of glide signal above 100 ft (transmitter or receivers).
‐ The difference between both radio altimeter indications is greater than 15 ft.
When the Autoland light comes on, Autoland must be discontinued (Refer to

CAT III WITHOUT DH).
WARNING OF EXCESSIVE BEAM DEVIATION
This warning is a flashing of the LOC and G/S scales on the PFD and ND ROSE ILS. It occurs
whenever :
‐ G/S deviation is greater than 1 dot (above 100 ft RA).
‐ LOC deviation is greater than 1/4 dot (above 15 ft RA).
WARNING ASSOCIATED WITH ILS "LANDING CAPABILITY"
Any downgrading in the aircraft’s capability for automatic approach and landing sounds a
triple-click aural warning.
FAILURE OF BOTH LOCALIZER AND GLIDESLOPE RECEIVERS
The PFD and ND (rose ILS mode) display red LOC and G/S flags (if the ILS pushbutton has
been pressed green). LOC and G/S scales disappear from the PFD.
If LOC or G/S modes are engaged and at least one AP/FD is engaged
