LVPs

Question 1

When is temperature correction required? What do you adjust?

Answer 1

Below -10*C on the ground

Applied to MDA and all check altitudes after FAF

Question 2

Lowest permissible FMA for autoland?

Answer 2

Cat 2

Question 3

Significance of yellow and green lights on taxiway?

Answer 3

Still within the protected area

Question 4

When can you use reverse idle on a wet runway?

Answer 4

Calculate performance with medium runway state. If it’s allowed with no reverse then you can use reverse idle

Question 5

What is approach autothrust?

Answer 5

Enables more responsive thrust with engines spooling much faster.

Active below 3200RA with flap 1

Question 6

Below what speed will selecting flap 1 give you 1+F?

Answer 6

100kts

Question 7

When is low energy warning active?

Answer 7

Below 2000RA when 2, 3 or Full are selected

Deactivates below 100RA

Question 8

What is considered a steep approach?

Answer 8

Anything between 3.5 and 4.5 degrees.

Flown stabilised

Question 9

Can you autoland from a steep approach?

Answer 9

No

Question 10

When will tail strike occur with compressed struts in A319/A320

Answer 10

A319: 13.9*
A320: 11.7*

Question 11

What is the significance of 1000ft in an LVP approach?

Answer 11

All ecam actions must be completed

Approach ban (drop in RVR below minima before means go around)

Question 12

What happens at 900ft on approach?

Answer 12

TCAS downgrades to TA

Question 13

What happens at 700ft on approach?

Answer 13

Data lock. PERF page can no longer be modified

Question 14

What are the stable approach criteria?

Answer 14

Landing Config
Speed +10/-5
On vertical profile
Max bank angle 15*

Question 15

What happens at approx 400ft on approach?

Answer 15

LAND is annunciated

FCU and MCDU lockout

Question 16

What begins at 200ft on approach?

Answer 16

AUTOLAND light activation. If it lights a go around must be perform unless visual

Question 17

What causes autoland light to activate? (7 items)

Answer 17

Loss of AP
Loss of G/S and LOC
Loss of LOC >15ft
Loss of G/S >100ft
Deviation from LOC/G/S
Rad alt discrepancy >15ft
Detection of long flare

Question 18

What happens at 370ft on approach?

Answer 18

PWS warnings downgrade to cautions

Question 19

Why is CATII minima often a random number whereas CAT3 minima is fixed?

Answer 19

CATII minima is generally not over the airfield so local terrain may alter the minima

Question 20

What affect does failed RVR counters have on approach capability?

Answer 20

Check table in QRH for affect on minima

Question 21

What RVRs are controlling for an LVP approach?

Answer 21

Touchdown always controlling, mid point and stop end can be controlling if relevant

Question 22

What value in minimum mid point RVR?

Answer 22

125m but can be reduced to 75m if automatic rollout used

Question 23

Can a CATIIIB approach be made onto a runway where no RVR guidance is available?

Answer 23

Yes

Only has to be an RVR counter on the airport for CATIIIB

Question 24

Of touchdown RVR is not available can you continue?

Answer 24

Yes as long as the midpoint and stop end are above required

Question 25

If midpoint RVR not available can you continue?

Answer 25

Yes as long as the others are above minimum required

Question 26

If stop end RVR is not available can you continue?

Answer 26

Yes as long as stop end is not relevant

Question 27

What is definition of Alert Height

Answer 27

Alert height is height above which a failure of one of the redundant parts of the autoland system would necessitate a go around. Below it can complete an autoland in fail passive state

Question 28

Difference between fail passive and fail operational?

Answer 28

When system fail passive, if there is a failure or downgrade the a/c would continue with no out of trim condition but a manual landing or go around is required

When fail operational, the a/c will continue in a fail passive state and will autoland

Question 29

What are the 5 conditions which necessitate go around above alert height?

Answer 29

Alpha floor
AP failure
Amber caution
Approach downgrade (triple click)
Engine failure

Question 30

What happens at critical heights below 1000ft on an LVP approach?

Answer 30

1000ft: stability criteria met
800RA: LDG inhibit
700RA: FMGC data lock
500RA: stability criteria met
