Question 1

What are the reasons for the Autoland Warning to flash below 200’ ?

There are 9 of them.

Answer 1

1/ The last AP disengages

Above 100 ft RA, with approach capability GLS CAT1 Autoland, or CAT2, or CAT3:

2/ The glide signal of the ILS transmitter fails, or

3/ The glide deviation is excessive.

Note: The glide deviation becomes excessive, when the glide deviation exceeds one dot.

Above 15 ft RA, with approach capability GLS CAT1 Autoland, or CAT2, or CAT3:

4/ The LOC signal of the ILS transmitter fails, or

5/ The LOC deviation is excessive.

Note: The LOC deviation becomes excessive, when the LOC deviation exceeds one quarter dot.

6/ One radio altimeter is failed (or rejected by the PRIM or the FWS), and the values provided by the two remaining radio altimeters differ by more than 15 ft

7/ A long flare is detected

Note: flare is long if the aircraft flies more than 1 000 m since FLARE engagement.

8/ A Thrust Control Malfunction (TCM) is detected during flare.

9/ A.FLOOR triggered at or below 200 ft.

When the AUTOLAND light flashes, the flight crew must discontinue the autoland.

Question 2

Below 1000’ the LOC and/or G/S scale FLASHES on the PFD. What does this indicate?

Answer 2

LOC is more than one quarter dot for 2 secs (above 15’ RA) or
The G/S is more than one dot for more than 2 secs (above 100’ RA)

Question 3

A Triple Click Aural sounds during approach. This means?

Answer 3

The precision approach capability downgrades

Question 4

The red LOC flag appears on the PFD CAPTs (F/Os) side means what?

Answer 4

The LOC receiver on the same side is failed

Question 5

The red G/S flag appears instead of the G/S scale on the CAPTs (F/Os) side means what?

Answer 5

The G/S receiver on the same side is failed

Question 6

What happens to the FD bars when the LOC (G/S) of one ILS/GLS receiver fails?

Answer 6

The roll (pitch) bar flashes on both PFDs

Question 7

What Operation for Automatic Landing must ROLLOUT mode be available?

Answer 7

CAT IIIB

Question 8

The AUTOFLT APPROACH CAPABILITY DOWNGRADE alert, which is crew awareness only, has 5 triggers. What are they?

Answer 8

1/ One or two flight control gyrometers is failed.

2/ One or two flight control vertical accelerometers is failed

3/ Discrepancy between one AOA and the two others

4/ Discrepancy between one slideslip and the two others

5/ discrepancy between one IRS and the two others

What are the 8 equipment not monitored by the FG?

Answer 9

1/ CAPT & F/O sidestick AP pb

2/ AUTOLAND light

3/ AP OFF alert

4/ DH Indicator

5/ Attitude indicator on PFD

6/ Attitude indicator on Standby instrument

7/ Windshield Wiper

8/ Windshield heating

Question 10

To perform an Automatic ROLLOUT in LAND2 or LAND3 SINGLE requires what from the Landing gear system?

Answer 10

Antiskid, nosewheel steering and Normal or Alternate braking

Question 11

For Automatic Approach, Landing and ROLLOUT of GLS CAT1, ILS CAT II and ILS CAT III, what are the maximum Headwind?

Tailwind?

and Maximum crosswind?

Answer 11

Headwind is 38kts

Tailwind is 15kts, except 10kts if airport is > 8000’ PA

Crosswind is 30kts. FAM 21.64.1 states 15kts.

All the above is Tower or ATIS provided.

Question 12

TASKSHARING

PM’s Task are to monitor what?

Answer 12

FMA and announce mode changes below 350’

Back up Automatic callouts

monitor A/C trajectory and announce deviation or attitude exceedance

Announce any failures.

Question 13

Visual reference for CAT II ops is?

Answer 13

At least 3 consecutive longitudinally aligned lights, being the centreline of the approach lighting system (ALS), the TDZ lights, or the RCLL, or REDL or a combination of these lights; and

A lateral element of lighting, being an approach lighting crossbar, landing threshold or a barrette of TDZ lights.

Question 14

Visual Reference for CAT IIIA with DH?

Answer 14

Fail Operational automatic landing system:
At DH – at least one centreline light.

Fail Passive automatic landing system:
At DH – at least 3 consecutive longitudinally aligned lights, being the centreline of the approach lighting system (ALS), or the TDZ lights, or RCLL, or REDL, or a combination of these lights.

Question 15

Visual Reference for CAT IIIB with DH?

Answer 15

at least one centreline light.

Question 16

Visual Reference for CAT IIIB without DH?

Answer 16

The pilot is not required to see the runway prior to touchdown.

Question 17

When conducting a CAT II approach with a Manual Landing. When must the A/P be disconnected by?

Answer 17

80’ RA. This ensures a smooth transition for the manual landing.

Question 18

Recommendation for Landing Lights during Approach & Landing?

Answer 18

Not to be used.

Question 19

Maximum Crosswind for Low Viz Take-off?

Answer 19

15kts

Question 20

Standard Take off minima is?

Answer 20

Ceiling of zero ft.

Visibility greater than 800m or

550m provided :
i.
The runway has illuminated edge lighting at space intervals not exceeding 60 m; and

ii.
The runway has centreline lighting or centreline markings; and

iii.
All lighting mentioned in sub-subparagraphs (i) and (ii) is supported by a secondary power supply with a switchover capability of 1 second or less; and

iv.
If the aerodrome is a non-controlled aerodrome or a controlled aerodrome where ATC is not in operation – the takeoff is conducted by day and the aerodrome is one at which the carriage of radio is mandatory.

Question 21

Definition of Runway Visibility RV?

Answer 21

The distance along a runway over which a person can see and recognise a visibility marker or runway lights.

Question 22

For Low Viz App & LDG. If a reported RVR is below a required RVR value, can you commence an Approach?

Answer 22

An approach may be commenced regardless of the reported RVR.

However, when making an approach, the Pilot In Command of the aircraft must not continue below 1,000 ft above aerodrome elevation if a controlling zone RVR is reported by ATC as continually less than the specified minimum for the approach.

Question 23

After passing 1000’, ATC advise a controlling RVR is below the required value, what must you do?

Answer 23

after passing 1,000 ft above aerodrome elevation, a controlling zone RVR is reported by ATC as falling below the specified minimum, the approach may be continued to the minima.

Question 24

Is the 380 approved for Fail passive CAT IIIB approach & Landing?

Answer 24

No. The 380 is approved for Category IIIB operations using fail operational automatic landing with roll out control guidance only.

Question 25

Can CAT II and CAT IIIA be conducted using Fail Passive?

Answer 25

Yes. The 380 is approved for:
Category II operations. Fail Operational or Fail Passive automatic landing system is required to touchdown for TDZ visibility minima less than 350 m RVR;

Category IIIA operations using fail passive or fail operational automatic landing

Question 26

What is the minimum Braking action reported by ATC for Low Viz Approach & Landings?

Answer 26

The braking action on the runway must not be reported by ATC as worse than medium.

Question 27

What is the G/S & LOC tolerance for CAT II & CAT III approaches?

And what extra procedure is applied below 100’ RA?

Answer 27

1/2 dot for G/S & LOC

For Low Visibility Operations, if the tolerances laid down for localiser or glideslope are exceeded at ‘100 above’ (Category II or Category III with DH) or ‘100’ (Category III with NO DH) and below, the First Officer shall use the standard call of “Outside Limits” and an immediate missed approach is mandatory.
