Question 7

Required Visual References for CAT I approach ?

Answer 7

One of the following visual ref :

• Elements of the approach light system.
• The threshold.
• The threshold markings.
• The threshold lights.
• The threshold identification lights.
• The visual glideslope indicator.
• The touchdown zone or touchdown zone markings.
• The touchdown zone lights runway edge lights.

Question 8

Updated OMA OCT22 - Required visual ref for CAT II or SA CAT II ?

Answer 8

The visual references must contain a segment of at least 3 consecutive lights being :

• The centre light of the approach lights, or
• Touchdown zone lights, or
• Runway centre line lights, or
• Runway edge lights, or
• A combination of these.

And a lateral element of the ground pattern:
* An approach lighting crossbar, or
* The landing threshold, or a barrette of the touchdown zone lighting.

Question 9

Updated with OMA OCT22 - Required visual ref for CAT III with DH ?

Answer 9

For Cat III with DH operations with fail-passive flight control systems, a pilot may not continue an approach below DH unless a visual reference containing at least 3 consecutive lights being:

• The centreline of the approach lights, or
• The touchdown zone lights, or
• The runway centre line lights, or
• The runway edge lights, or
• A combination of these is attained and can be maintained.

Question 10

Updated with OMA OCT22 - What is the minimum RVR for Takeoff ?

Answer 10

First officer 550M

Captain 125M

Question 11

Updated with OMA OCT22 - How many consecutive approaches can be flown ?

Answer 11

No more than 2 approaches when 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 12

Updated with OMA June 2024 - What is the approach Ban ?

Answer 12

An instrument approach may be commenced regardless of the reported RVR/VIS. If the reported RVR/VIS is less than the applicable minimum the approach shall not be continued:

• Below 1000ft above aerodrome
• or Into the final approach segment in the case where the DA/H or MDA/H is more than 1000 ft above the aerodrome.

In case of no reported RVR and reported VIS is less than the minimum but CMV is higher or equal to the minimum then approach can be continued to DA/H or MDA/H

thanks for the correction George

Question 13

Updated with OMA OCT22 - What is the controlling RVR ?

Answer 13

The controlling RVR is the TDZ for approach with MDA, DA or DH. If the TDZ RVR is not reported, then the midpoint RVR should be the controlling RVR.

When No RVR reported => CMV should be used for continuation of approach except in LVO.

Question 14

Updated with OMA OCT22 - On a CATIII without DH can you land if only one RVR is reported on the airport (can be on the opposite side of the Airport)

Answer 14

For CAT III without DH, Air Ops requires only one RVR value on the airport.

Question 15

Updated OMA OCT22 - What is the relevant RVR on Take off and on landing ?

Answer 15

NOT APPLICABLE TO AUSTRIAN AOC ONLY UK

Take-off

RVR for that part of the runway used to accelerate to V₁ followed by a rejected take-off and deceleration down to a speed of approximately 60 knots.

Landing

RVR for that part of the runway used during the high speed phase of the landing run down to a speed of approximately 60 knots.

Question 16

Updated OMA OCT 22 - Can we fly SA CAT I ?

Answer 16

Easyjet Europe does NOT hold the approval

Question 17

The reported RVR value for takeoff is less than the required value for the initial part of the takeoff run, can the takeoff be started ? if yes how ?

Answer 17

The reported RVR value representative of the initial part of the take-off run can be replaced by pilot assessment. OMA Note 8.1.3.3
So if the number of centerline lights allows the pilot to determine a higher than required vis the take off can be started (centerline lights are spaced with 15m, edge 60m)

Question 18

What are the consequences on the required RVR to use rollout guidance for landing ?

Answer 18

the mid point RVR is reduced to 75m instead of 125M
OMA 8.1.3.3.1

Question 19

Updated with OMA OCT22 - When are you allowed to used converted met vis to RVR ?

Answer 19

If an RVR is not available a CMV may be substituted for the RVR except for:

• Takeoff minima or
• Continuation of an approach in LVO

For planning purposes, a factor of 1.0 should be used. Which mean it cannot be used to improve the vis using a factor at planning stage.

OMA 8.1.3.5

Question 20

What is required on ground and in the A/C to perform an automatic rollout ?

Answer 20

• Cat II ground equipment
• NWS and antiskid
• Not approved on contaminated RWY

Question 21

What are the consequences of the loss of one engine for a low visibility approach ?

Answer 21

The aircraft become Cat III with DH so only CAT 3 single on the FMA

Autoland in config FULL only for A320, Config 3/FULL for A319 and neo

Question 22

What is the height of the Alert Height ?

Answer 22

100ft

Question 23

What does Fail operational mean ?

Answer 23

It means that in case of a failure below the AH the A/C can do the approach, flare and landing automatically

Failure above AH, the A/C become fail passive

Question 24

What does fail passive mean ?

Answer 24

It means that in case of a failure below alert height there is no significant out of trim condition or deviation on flight path but the landing cannot be completed automatically

Question 25

What are the required Wx for a visual approach ?

Answer 25

Vis 5000m

Ceiling 2500ft

Question 26

What is the minimum wx for FO to do a circling approach ?

Answer 26

Mini vis 5000m

Question 27

What are the required visual references for circling approach ?

Answer 27

runway environment: threshold, approach light or other marking on aerodrome

Question 28

What are the required visual references for RNAV approach ?

Answer 28

Airport environment

Question 29

Updated with OMA OCT22 - What is the lowest RVR you can take off without LVP ?

Answer 29

550m

Question 30

Ground equipment fail during the approach, what are the associated consequences and following actions ?

Answer 30

if the failure happen below 1000ft you can continue, above you need to asset if you can or not continu.
