Captain must brief:
Ø F/O must
make 400’ “Land Green” call.
Ø 100 Above
procedures (Captain - “Continuing”)
Ø Minimums
procedures (Captain - “Landing” or “Go Around”)
Note: any CAT II RA not AUTH approaches are based on inner
marker. You may use the inner marker GS
crossing altitude in the MDA as a reminder.
AH stands for Alert Height and allows for continuing the
approach only on electronic indications (no visual confirmation of runway
environment required). The Airbus 319/320/321 requires that CAT 3 Dual be
annunciated in the FMA before AH is used. When entering Radar Altimeter
information in the FMGC on the Approach page use 100’ in the DH window for the
AH. Autocallouts will be made at 100 above and Minimums as DH is being selected
on the Approach page. This will allow the pilot to have a reminder at 100’ AGL
but the approach may be continued as long as all indications are normal and the
reported RVR remains at or above the minimum for the approach. This means it is
possible that the runway may not be seen by the pilots before minimums. When
shooting a CAT II or III approach the PF must make callout of CAT 3 dual (or single) or CAT 2 based on
FMA information when armed for approach. NOTE: Above 8,200’ AGL (max valid
radar altimeter range) FMA will show CAT 1, confirm FMA below 5,000’ AGL.
If CAT 3 Dual is not shown in the FMA (for example CAT 3
Single or CAT 2) then DH must be used if doing a CAT II or III and runway must
be seen. Dual will be shown when both autopilots are in use, and Single when
only one autopilot is in use or loss of some other required redundant system.
Engine-out approaches limited to CAT IIIA (CAT 3 Single, requires 50’ DH).
Captain retards throttles on the 10’ “Retard” callout, disconnect autopilot by
60 kts. on runway.
The autoland fail light will flash red if the following
conditions occur below 200’ while in LAND mode (PH 14.1.6):
Ø Both AP’s
off below 200’ RA
Ø Excessive
LOC (¼ dot – above 15’ RA) or GLIDE (1 dot – above 100’ RA) deviation – LOC and
GLIDE scales flash
Ø Loss of
LOC (below 15’) or GLIDE (below 100’) signal
Ø Difference
between radar Altimeters is greater than 15’ (FD bars flash)
LAND green on FMA at 400 ft. indicates that the autopilot is
“locked in” and will “ignore” inputs on the FMU (autopilot panel). Basically at
this point it is only looking for a TOGA selection or to complete the landing.
CAT II/III Go-Around Mandatory if –
Ø No LAND
GREEN
Ø Autoland
warning light comes on
Ø Autoland
capability degrades below 1000’ (CAT 3 DUAL to CAT 3 SINGLE or CAT 2)
Note: If autoland capability degrades above 1000’ the pilots
have the option of changing the minimums on the PERF APPROACH page if this is
done before 500’ AGL and the captain understands the new minimums are a
decision height.
If auto callouts are not available the F/O (PM) will need to
make the 100 Above and Minimums callouts.
Autopilot should be disconnected on ground before 60 kts.
Remember that the autopilot will be steering the aircraft through nosewheel
steering until disconnected.
Practice autoland approaches may be done on CAT I runways
only if (PH 18.6.11):
Ø Runway is
listed as approved for autolands in Airport Advisory pages
Ø Approach
is done in CAT I or better weather conditions.
Use published CAT I DA on PERF APPR MDA prompt
Note: when doing autoland during CAT I or better weather
the ILS hold line is not being protected and signal may be poor. ATC has a long
checklist to run before CAT II/III is actually flown and this will not be done
during CAT I weather.
The
material “below the line” is not from PH but is added if you consider it
helpful.

Autoland Approach Briefing – For an autoland approach,
the Captain will include the following items as part of the briefing:
-
FMA
annunciations (i.e., LAND green) and First Officer procedures
-
Procedures
at “100 ABOVE” callout.
-
Procedures
at “Minimums” callout
EXAMPLE:
“This will be an Autoland
Approach. At 400’, verify the FMA annunciates LAND green. At the ‘100 ABOVE’
callout, I will respond ‘CONTINUING’. You continue to monitor the flight
instruments and FMA. At the ‘Minimums’ callout one of two things will occur:
++++++++++++++++++++++++++++++++++++++++++++++++++
We are using ___(AH or DH) today which means that I will verify the runway environment ___(electronically or visually) with ___ (100’ or 50’) set in the DH window. We need a minimum capability of _____(CAT III DUAL, CAT III SINGLE, CAT II) annunciated in the FMA to fly this approach. We need a minimum RVR of ___ for this approach.
