Autoland/LVPS Flashcards
When is retard called on a normal landing and an autoland?
Normal landing = 20ft RA
Autoland = 10ft RA
RVR below minima below the approach ban (1000ft AGL)
Continue to DH
LTS Cat 1 minima and visual reference
400m RVR
200ft DH
Visual ref = 3 lights and a lateral element
(CAT 2)
Cat 2 minima and visual reference
300m RVR
100ft DH
Visual reference = 3 lights and a lateral element
OTS Cat 2 minima and visual reference
350m RVR
100ft DH
Visual ref = 3 lights and a lateral element
When would OTS Cat 2 be used?
What is the advantage over Cat 2?
Can use a lesser lighting system.
Mitigated by the use of a higher RVR and an autoland.
NO LAND MODE
on an autoland
Go around!
AP disconnects at 800ft
Go around!
Alpha floor activation at 100ft
Not visual
Go around!
Alpha floor activation at 500ft
Go around!
RVR below minima above the approach ban
Go around/discontinue the approach
Engine failure at any altitude or height
If you can secure the engine, sort the downgrade and change the minima by the approach ban continue.
If not Go around!
Below 1000ft AGL Go around!
Autoland light on at 200ft, visual
(Technically) disconnect the AP and continue visually
Amber caution at 600ft
Go around!
Autoland light on at 200ft, not visual
Go around!
Amber caution at 90ft
Continue
already below the alert height
Loss of Cat 3 below the approach ban, visual
(Technically) disconnect and continue visually.
If not visual, Go around!
No flare at 30ft, visual references insufficient
Go around!
No flare at 30ft, visual
Disconnect AP and continue visually
AP off at 100ft, not visual
Go around!
Red autoland light
Engine fire on approach
CONTINUE
When does the autoland light activate and when do you consider it?
Arms at 200ft
Activates when
- Loss of both APs
- Loss of LOC or greater than 1/4 dot, above 15ft RA
- Loss of G/S or greater than 1 dot, above 100ft RA
- Rad alts differ by 15ft
- FMGCs detect a long flare
When would LTS Cat 1 be used?
What is the advantage over Cat 1?
When a lesser visibility can be accepted, a lower RVR.
Mitigated by use of autoland and Cat 2 visual reference
What is NPA minima?
750m RVR
250ft MDH
Below the approach ban what 5 things would you go around for?
What noises do they make?
- AP disconnect - cavalry charge
- Downgrade/loss of cat 3 - triple click
- Amber caution - single chime
- Engine fail
- Alpha floor
When do LVPs come into force?
600m RVR
200ft cloud base (BKN or OVC)
Cat 1 minima and visual reference
550m RVR
200 ft DH
Visual reference = runway or approach lights
Cat 3a minima and visual reference
200m RVR
50ft DH
Visual reference = 3 lights
Cat 3b No DH minima and visual reference
75m RVR
NO DH
No visual reference
Cat 3b with DH minima and visual reference
125m RVR
50ft DH
1 centreline light
Anti skid fails
Downgrade to Cat 3a
Minimum DH 50ft
Disengage AP at touchdown
Incorrect course set at 350ft
Downgrade to Cat 2
Minimum DH 100ft
Disengage AP at 50ft latest
Nose wheel steering failed
Downgrade to Cat 3a
Minimum DH 50ft
Disengage AP at touchdown
What happens at 800ft on an autoland approach?
Landing inhibit
What happens at 700ft on an autoland approach?
Data lock FMGC and ILS tuning locked
What happens at 400ft on an autoland approach?
Should get LAND FMA, 350ft at the latest, as well as the FCU modes locking.
PM checks ILS course is correct
If no LAND - GO AROUND
What happens at 200ft on an autoland approach?
Autoland light arms
What happens at 40ft on an autoland approach?
Should get FLARE FMA
If no FLARE and not visual - GO AROUND
If no FLARE and visual - disconnect and continue manually
What happens at 30ft on an autoland approach?
THR IDLE FMA
What happens at 10ft on an autoland approach?
‘Retard’ callout
What is the effect of rollout or lack of rollout guidance on RVR?
For Cat 2 and Cat 3a if you have rollout guidance the midpoint RVR can be reduced to 75m. If not the midpoint RVR is 125m
Do you need an RVR for the stop end?
Only if its going to be used in the landing roll.
What is the minimum RVR with an unqualified crew member?
150m
What is the stop margin?
= The portion of the runway not used for stopping.
= ASDA - ASD. But very conservative when using a flex temp
