Low Visibility Ops

Question 1

What is the difference between LVOs and LVPs?

Answer 1

LVOs are what the airline do. LVPs are what the airport does

Question 2

What is the difference between CAT3DUAL and CATIIIB?

Answer 2

CAT 3 DUAL is an aircraft capability. CAT III B is a facility offered by the airport. In order to take advantage of the CAT III B facility, aircraft must have CAT 3 DUAL capability on the FMAs

Question 3

To take advantage of CAT III A facility at an airport, what is the minimum FMA required to take advantage?

Answer 3

CAT 3 SINGLE

Question 4

To take advantage of CAT II facility at an airport, what is the minimum FMA required to take advantage?

Answer 4

CAT 2

Question 5

To take advantage of CAT III B facility at an airport, what is the minimum FMA required to take advantage?

Answer 5

CAT 3 DUAL

Question 6

What does ‘fail operational’ mean?

Answer 6

In the event of a failure below alert height, the approach, flare and landing can still be completed automatically. In the event of a failure, the automatic landing system will operate in a fail-passive system

Question 7

What does ‘fail passive’ mean?

Answer 7

In the event of a failure, there is no significant out-of-trim condition or deviation of flight path or attitude, but the landing is not completed automatically. This would mean that the pilot would need to take control in the event of a failure

Question 8

What is the ‘Alert Height’?

Answer 8

Specified radio height based on the characteristics of the aircraft and its fail-operational landing system.

Question 9

What would you do in the event of a failure of one of the required redundant operational systems in the aircraft above the alert height?

Answer 9

Discontinue the approach and go-around, unless reversion to a higher decision height is possible

Question 10

What would you do in the event of a failure of one of the required redundant operational systems in the aircraft below the alert height?

Answer 10

Ignore the failure and continue the approach

Question 11

In easyJet, can an FO be PF for an autoland?

Answer 11

No

Question 12

What is easyJet’s policy if planning a CAT II approach?

Answer 12

LVPs must be in force, and autoland must be planned

Question 13

What are the minimum RVRs required for takeoff?

Answer 13

Check in AOI section of LIDO

Question 14

What ceiling or RVR will cause an airport to introduce LVPs?

Answer 14

Ceiling less than or equal to 200ft

RVR less than or equal to 600m

Question 15

What is the difference in taxiing in LVPs?

Answer 15

Do nothing when moving - all checks must be done at a standstill.
Thoroughly brief taxi routing, and use headings to confirm.
Consider lights to make yourself more visible
OETD prohibited

Question 16

Where do you find a list of the required equipment for an autoland?

Answer 16

In the QRH - OPS 4

Question 17

When should the LVO PA be made before departure?

Answer 17

Prior to taxi

Question 18

If planning a takeoff in LVPs, when should the pilots inform the cabin crew?

Answer 18

Prior to doors closed

Question 19

When is the approach ban point?

Answer 19

1000ft above airport elevation, or in the final approach segment in the case where DA/H or MDA/H is more than 1000ft above the aerodrome

Question 20

What is the significance of the approach ban?

Answer 20

You can continue past the approach ban point if the TDZ RVR and MID/STOP (if reported and relevant) are above minimum.

Question 21

If RVR deteriorates below minimum after you have passed the approach ban point, what are your options?

Answer 21

Approach may be continued to DA/H or MDA/H (in the case of CAT 3B no DH - to land)

Question 22

What is the purpose of CAT I LTS?

Answer 22

It is a category of ILS approach in which the required RVR can be reduced below 550m on the basis that autoland will be used. It can be used on authorised runways which for various reasons cannot support CAT II/CATIII operations

Question 23

What are the requirements for a CAT I LTS?

Answer 23

Autoland mandatory
LVPs must be in force
Suitability promulgated in the AIP
Minima published in instrument approach chart

Question 24

What is an OTS CAT II? When are you likely to see this?

Answer 24

Other than standard CAT II. Where some or all of the elements of the precision approach or runway light system required for a standard CAT II approach are not available. The deficiency in lighting is offset by use of the autoland

Question 25

What are the requirements for OTS CAT II?

Answer 25

LVPs in force
Autoland mandatory
Required visual reference is the same for CAT II
Minima for OTS CAT II published on the instrument approach chart

Question 26

What are the required visual references for a CAT I approach?

Answer 26

Elements of the approach light system, threshold, threshold markings, threshold lights, threshold identification lights, visual glideslope indicator, touchdown zone, touchdown zone markings, touchdown zone lights, runway edge lights

Question 27

What are the required visual references for a LTS CAT I approach?

Answer 27

As per CAT II

3 consecutive lights and a lateral element

Question 28

What are the required visual references for a CAT II approach?

Answer 28

3 consecutive lights and a lateral element

Question 29

What are the required visual references for a OTS CAT II approach?

Answer 29

As per CAT II

3 consecutive lights and a lateral element

Question 30

What are the required visual references for a CAT IIIA approach?

Answer 30

3 consecutive lights
