Fail operational means
After failure below ALERT HEIGHT app flare ldg can be completed automatically (CAT3 DUAL)
Fail passive means
After failure the landing cannot be completed automatically (trim / attitude) CAT3 SINGLE
Alert height is
200ft RA
- above AH an automativ app will be discontnued after a failure of the ground or airborne equip
- below AH GA only for AUTOLAND light (ATC)
Autoland light flashed red below 200ft in case of
AP lost
Excessive LOC / GS DEV
LOC signal above 15ft or glide slope lost above 100ft
RA difference 15ft
LVTO
400m CM1 PF min 125 RVR
Approach ban
Until 1000ft RVR must be above limits
Below 1000ft RVR may fail below limits but never below 75m
Min RVR for app 3a/3b
200/75/75 vs 75/75/75
What happens at 700ft RA
FMS data frozen - ILS tune inhibit, target speed etc
At 350ft RA..
LAND must appear - it ensures that approach guidance will be correct
Land might come below 300ft which is
too late the triple click usually comes up before
Below 400ft RA the FCU
is frozen - any action of the FCU is disregarded by the FMGC
LAND mode can only be disengagegd by
GO AROUND - TL to TOGA
Once AC is on GRD if TL are set to TOGA …
this engages SRS / GA TRK modes and sets AP to OFF

What is PLD Partial Lift dumping?
With MLG touchdown with REV idle the GRD spoilers partially deploy to 20° this increasing the load on wheels - then the GRD spoilers automatically fully extend
