LVO / Winter OPS

Question 1

Below what visibility limit is considered LVO?

Answer 1

Below 600m.

Question 2

When should we be doing F/CTL and brake test + taxi flow?

Answer 2

As pushback is completed, before commencing taxi.

Question 3

Minimum RVR for take-off for all three rwy segments? (General)

Answer 3

125/125/125

Question 4

Minimum visibility limit for FO?

Answer 4

400m

Question 5

What is the distance between rwy centreline lights?

Answer 5

15m

Question 6

What is the most precise approach that could be done with just ONE autopilot?

Answer 6

CAT 3 SINGLE

Question 7

Can you do an AUTOLAND with just one engine operative?

Answer 7

Yes, the aircraft is perfectly capable.

Question 8

What do we do if “FLARE” does not appear?

Answer 8

AP OFF and we take over.

Question 9

We are performing a CAT xxx approach into EHAM. We come up with a fire. The decision made is to continue. At 50ft, “FLARE” does not display on the FMA. What do we do?

Answer 9

AP OFF, take over and land anyway. A GA would be more risky than landing the aircraft in these conditions.

Question 10

De-icing. What are the 3 different types of de-icing and a their colour?

Answer 10

🇮🇪

TYPE I
1. ORANGE: Extremely low temps.

TYPE II
2. COLOURLESS or PALE STRAW: Diluted anti-icing fluid

TYPE IV
3. EMERALD GREEN: same as type II

Question 11

What is the difference between LVO and LVP?

Answer 11

LVO - AIRLINE based operations
LVP - AIRPORT based operations

Question 12

Describe ‘fail operational’ and ‘fail passive’ systems.

Answer 12

• F. OPER.: automatic landing ✅ CAT 3 DUAL.
  • F. PASS.: not out of trim condit. But automatic landing ❌ CAT 3 SINGLE, CAT2, CAT1.

Question 13

CAT I, CAT II and CAT III are considered low visibility approaches. True or false?

Answer 13

FALSE.

Only CAT II and III. CAT I is not a low visibility approach.

Question 14

What is an approach ban?

Answer 14

APPROACH BAN is a type of app in which you can continue past the approach ban point provided the TDZ RVR, and MID/STOP if reported and relevant, are above minimum.
- 1000 ft AAL. (BARO ALTITUDE‼️)
or
- Into the final app segment in the case where the DA/H or MDA/H is more than 1000ft AAL.

Question 15

Could you do an approach ban if RVR is reported before the approach ban point? And after?

Answer 15

If before that point RVR reported: Discontinue app.

If after approach ban point: Continue TO MINIMA.

Question 16

STANDARD CALL-OUTS LVO APP.

Answer 16

[500ft RA] : PM “500ft, stable/Not stable, Go Around”
PF “Checked/Go Around flaps”

[400ft-350ft RA] “LAND” Checks ILS course on PFD

*[200ft RA] AUTOLAND LIGHT: Red line starts: GO AROUND

[100ft RA] Alert height: PM “One hundred”; PF “Continue”

[50ft RA] “FLARE” PF: “Flare”
[30ft RA] “THR IDLE”
[10ft RA] “ROLLOUT”

Question 17

You are at 10ft over the runway and “AUTOLAND” light is not illuminated. What would you do?

Answer 17

Go around. The aircraft is not doing an autoland, it hasn’t been briefed, no flare, no rollout = too risky to continue.

Question 18

What are the 3 factors that may make us go around BELOW 1000ft? (LVO)

Answer 18

> Master caution or
Triple click ➡️ GA
Master warning ➡️ Pilot discretion (e.g. ENG FIRE)

Question 19

LVO APP. You are at 700ft and the ND on the PF fails. What would you do?

Answer 19

Continue as it doesn’t affect landing capability of the aircraft.

Question 20

LVO APP. You have an engine failure at 550ft. What would you do?

Answer 20

“Go around”. It hasn’t been briefed so it may be a bit safer to do it rather than land. But the aircraft is perfectly capable of doing it.

Question 21

LVO APP. What are the 3 factors that may make us go around BELOW 200ft?

Answer 21

> Master caution or
Triple click ➡️ GA
AUTOLAND red light ➡️ GA

Question 22

LVO APP. What is the only warning you might get BELOW 100ft that may you make a go around?

Answer 22

The only warning you get is AUTOLAND LIGHT and if you do get it = GA❗️

Question 23

What is the minimum cloud base limit?

Answer 23

200ft

Question 24

RVR and minima for CAT I,II,III?

Answer 24

CAT I - 550m / 200ft
CAT II - 300m / 100ft

CAT III - 175m / WITH DH 50ft
CAT III - 75m / NO DH

Question 25

Where do I see the take off minima of an airport?

Answer 25

AOI - Departure section.

Question 27

Ice shedding procedure, A319-A320 CEO & A320-A321 NEO.

Answer 27

CEO: Parking brake ON or brake with pedals, 70% N1 for 30s at intervals of 30mins.

NEO: Parking brake ON or brake with pedals, 50% N1 for 5s at intervals of 60 mins.

(Normally on the rwy for both, right before take off)

Question 28

QNH correction procedure. (hPA per degree)

Answer 28

Only when QNH is reduced. 2°C per hPA.
