LOVIS CAT3 Flashcards
Autoland info is in
OM-B 2.2.85
CAT2/3 ops allowed if
RWY authorized
Crew authorized
Airplane capability
Airborne / GRD equip sufficient
A330 min weight for autoland
123to
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
Flare come on at ….. ft THR idle at or below ….ft
60 / 30
Auto RETARD callout is …ft for manual landing as an indication and ….. for autoland as an order
20ft / 10ft
Pilot eyes are approx in …..ft when crossing RWY threshold
60ft

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
High airport elev 1000ft and or low QNH 980 adds … % to actual ldg distance
10
A 10% excess in app speed adds …. % to actual ldg distance
20
A 50ft excess in ALT at RWY threshold (100ft at RWY THR) adds some …. metres to the actual ldg distance
300
A long flare adds to some ….% to actual ldg distance
30%
Braking - by
GRD spoilers 30% // Thrust reversers (25%) (down to 70kts) // Wheel brakes
Time from TD to max REV thrust…
6 - 14sec
MED autobrake
.3g or 6kts/sec
LO is selected…
.15g or 3kts/sec
What is the decel rate with max manual braking?
10kts/sec .5g
Brake hot warning ist to prevent …
fire after LG retraction in case of hyd fluid leakage
The potential problem of brake binding occures when..
on ground one wheel reaches 600° deg f.e while the all other wheels indicate 400°-450°
Partial loss of braking may occur if …
one wheel shows 60° whereas the others are beyond 200°
DECEL light is not an indicator of the A/brake operation as such but …
that the decelartion rate is reached
In case of an reported eng tailpipe fire …
shutdown eng with master switch (NOT ENG FIRE PB) a n d CRANK the ENG using opposite or APU bleed or ext pneumatic power (ENG MASTER OFF - AIRBLEED PX ESTABLISH - ENG MODE SEL CRANK / MAN START ON )
Eng certification criteria ensures that max time to accelerate from 15%to 95% of the GA thrust is
5sec
Airframe certification criteria ensures that within …sec thrust from app idle allows to fly minimum “LDG climb gradient” of …..
8sec // 3.2%
At 700ft all data is coming from
FMS and are frozen
At 350ft RA
LAND must appear
Below 400ft RA
FCU is frozen
