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.
