Low Visibility & cold weather

Question 0

The approach controller offers you a CAT 2 approach. What is the minimum aircraft capability as show on the FMA’s to accept this approach?

Answer 0

CAT2

Question 1

Airport offers you a CAT3A approach. What is the minimum aircraft capability to fly this approach (what must the FMA’s show)?

Answer 1

The FMA’s must show CAT3 single. CAT3B, CAT3A, CAT2 is the airport ILS capability. In other words the facility offered by the airport. CAT3 duel CAT3 single show the Aircraft capability.

Question 2

What is the lowest FMA which makes an AB do an autoland?

Answer 2

CAT2

Question 3

For a CAT3A approach. The FMA’s must show … or … and at DH you must see …

Answer 3

CAT3 single, CAT3 dual, 3 consecutive lights

Question 4

For a CAT3B approach no DH. The FMA’s must show … and the minimum visual reference is …

Answer 4

CAT3 dual, none. There is no requirement to see anything.

Question 5

For a CAT3B approach with DH. The minimum visual reference is?

Answer 5

1 light

Question 6

For a CAT2 approach the minimum visual reference required is?

Answer 6

3 consecutive lights and a lateral element.

Question 7

RWY taxi-holding position. The last holding position prior to entering a RWY. How does it look like? Draw it on a piece of paper.

Answer 7

Question 8

CAT2/3 holding position. How does it look like? Draw it on a piece of paper. It also means a closer CAT1 holding position is provided.

Answer 8

Question 9

Autoland warning light. When is it armed? What does it tell you? In which four cases does it flash?

Answer 9

• armed below 200’ RA - It flashed in case of failures that require the interruption of an automatic landing. It basically tells you that the airplane is unable to do an autoland. - Both AP’s off, excessive LOC/GLIDE deviation, loss of LOC/GLIDE signal and difference between both RA indications of > 15’.

Question 10

Landing capability with one engine out?

Answer 10

CAT3A

Question 11

You are taxiing out for departure in freezing fog. When do you need to perform the ground engine ice shedding procedure?

Answer 11

When taxiing in icing conditions prior to higher thrust operation on ground ice shedding must be performed. 70% N1 minimum for approximately 30 seconds. - Inform ATC - Consider advising cabin crew and passengers

Question 12

When you are taking off from a runway with less then 25% contamination. What do you put in the EFB performance module?

Answer 12

wet figures, because the runway is not contaminated.

Question 13

Clean aircraft concept. However what kind of “contamination” can we accept?

Answer 13

PRO-SUP-91-30 Exterior Inspection: Thin hoar frost is acceptable on the upper surface of the fuselage, radome and engine exterior surfaces. On the underside of the wing tank area, a maximum layer of 3 mm of frost will not penalize take off performance.

Question 14

During the walk around you discover ICE on the fan blades. What would you do?

Answer 14

This will be an engineering function. Call MOC for further guidance.

Question 15

You experienced (airframe) ice accretion on approach. VAPP must not be lower than VLS + .. in CONF FULL or VLS + .. in CONF 3.

Answer 15

+ 5 KTS or +10 KTS

Question 16

LVP’s are in force and the runway is covered in snow. No aircraft defects. What is your landing capability?

Answer 16

Automatic roll-out has not been demonstrated on a snow covered or icy runway. If so = CAT3A only due to no roll-out.

Question 17

Maximum speed for the use of windshield wipers?

Answer 17

230 kt

Question 18

Approach ban?

Answer 18

The approach may not be continued beyond 1000’ if the reported RVR is below the published minima for the approach. After 1000’ if the RVR becomes lower than the minima, the approach may be continued.

Question 19

Flying a CAT3B approach. At 1200’ you hear a triple click, the FMA shows CAT3A. What would you do?

Answer 19

If you have at least 200 m RVR you can REVERT to higher minima and proceed to a new DH (only when above 1000’).

Question 20

LAND on the FMA what does this indicate?

Answer 20

LOC and GS track modes are active and at least one RA is available. After the LAND annunciation the approach mode may only be disengaged by selecting go-around mode. Displayed at 350’ RA. When not displayed perform GA.

Question 21

In case of CAT3B without DH, the pilot should enter .. in the DH field of the MCDU.

Answer 21

NO

Question 22

On snow-covered grounds, reversers should be stowed when the aircraft speed reaches ..

Answer 22

25 KT OMB CH2 Normal procedures
