Question 1

Autoland

What is the Alert height ?

Answer 1

The Alert Height is a specified radio height, based on the characteristics of the aircraft and its fail-operational landing system.

Question 2

Auto land NO DH description from 1000ft

Answer 2

1000ft - “One thousand”
800ft - LDG inhibit
700 ft - FMGC data locked e.g.: ILS course & freq, PERF app)
500ft - “Five hundred - Stable”
400 ft - FCU modes locked.
350 ft, “LAND” must be displayed on FMA. CM1 checks ILS COURSE
200 ft, AUTOLAND RED light armed.
100 ft - “One hundred” - “Continue”
40ft or below - “FLARE”
30ft or below- THR IDLE
10 ft - RETARD auto call out as an order.
0 ft -“ROLLOUT”

Question 3

RED AUTOLAND LIGHT triggered by

Answer 3

Loss of both APs
Loss of LOC until 15ft
Loss of GS until 100ft
LOC/GS Deviation
RA Discrepancy > 15ft
FMGS detects long flare
FMGS detects early/untimely flare

Question 4

Failure during approach.
What must be completed by 1000ft in order to continue?

Answer 4

ECAM/QRH Procedure—>Complete
QRH - Required Equipment for CAT II/III—>Check
APP LDG CAPABILITY—>Check
RVR—>Check
DH—>Adjust

Question 5

Answer 5

-AP DISC PB
-“AP OFF” ECAM WARNING
-“AUTOLAND LIGHT”
-RUDDER TRAVEL LIMIT SYS ( 1 if crosswind higher than 12kts)

Question 6

LVOs
Minima + Required Visual References for a:

CAT II approach

Answer 6

100ft RA
300m / 125m / 75m RVR
3 consecutive lights and a lateral element

Question 7

LVOs
Minima + Required Visual References for a:

SA CAT II approach

Answer 7

100ft RA
350m / 125m / 75m RVR (with rollout mid 75m end 75m)
3 consecutive lights and a lateral element

Question 8

LVOs
Minima + Required Visual References for a:

CAT III A approach

Answer 8

50ft RA
175m / 125m / 75m RVR
3 consecutive lights

Question 9

LVOs
Minima + Required Visual References for a:

CAT III B approach

Answer 9

n/a
75m / 75m / 75m RVR

No visual references required (unless there is a DH, then 1 light)

Question 10

Take off alternate requirements.

Answer 10

A suitable aerodrome must be available when performance or meteorological conditions prevent an immediate return to the departure aerodrome. A take off alternate must be located within a threshold DIST based on 1hr flight time OEI speed in still air and ISA conditions. Increased LDG minima for overweight conditions must be considered.
TO ALTN must be within 320nm.

Question 11

Take off:
Lowest RVR for FO as PF

Answer 11

550m

Question 12

LVOs
Minima + Required Visual References for a:

SA CAT I approach

Answer 12

150ft aal
400/450m RVR - (if reported: 125m/75m)
3 consecutive lights and a lateral element (as per CAT II)

Question 13

LVOs

Lowest minima without automatic rollout:

Answer 13

CAT III A
50ft - 175m /125m/75m

Question 14

LVOs

How many approaches can be attempted?

Answer 14

No more than two successive approaches may be flown when there has been a go-around due to weather conditions unless there has been a significant improvement to the weather which would allow a safe landing, or a state of emergency exists.

Question 15

After landing what do alternating red/white centreline light mean?

Answer 15

900m to go

Question 16

After landing what do continuous red lights mean?

Answer 16

300m to go.
