Required Visual References for CAT I approach ?
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.
Required visual ref for CAT II or LTS CAT I ?
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.
Required visual ref for CAT III A ?
For Cat III A 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.
What is the minimum RVR for Takeoff ?
First officer 400M
Captain 125M
How many consecutive approaches can be flown ?
No more than two successive approaches may be flown when there has been a go-around due to weather conditions unless there has been a significant improvement to the weather, or a state of emergency exists.
In exceptional circumstances, a third approach may be flown when a go-around has been carried out for non-weather related reasons providing the Commander is satisfied that landing is assured.
What is the approach Ban ?
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 DA/H MDA/H if more than 1000ft
If, after passing 1000 ft above the aerodrome, the reported RVR/VIS falls below the applicable minimum, the approach may be continued to DA/H or MDA/H.
How many RVR value are required for CAT III B without DH ?
Only one RVR Value at the airport
What is the controlling RVR ?
The touchdown RVR is always controlling for all instrument approach with MDA, DA or DH.
If reported and relevant, the mid point and stop end RVR are also controlling.
On a CATIII B approach without DH can you land if only one RVR is reported on the airport (can be on the opposite side of the Airport)
For CAT IIIB without DH, Air Ops requires only one RVR value on the airport.
What is the relevant RVR on Take off and on landing ?
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.
How is a LTS CAT I flown ?
Autoland and LVP must be in force
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 ?
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)
What are the consequences on the required RVR to use rollout guidance for landing ?
the mid point RVR is reduced to 75m instead of 125M
OMA 8.1.3.3.1
When are you allowed to used converted met vis to RVR ?
For landing in flight (not planning)
after conversion RVR more than 800m
No RVR are reported
OMA 8.1.3.4
What is required on ground and in the A/C to perform an automatic rollout ?
- Cat II ground equipment
- NWS and antiskid
- Not approved on contaminated RWY
What are the consequences of the lost of one engine for a low visibility approach ?
The aircraft become Cat III A so only CAT 3 single on the FMA
Autoland in config FULL only for A320, Config 3/FULL for A319 and neo
What is the height of the Alert Height ?
100ft
