Low Visibility Ops 3 Flashcards
What are the minima for a CAT II OTS approach?
100ft RA
RVR 350m
What are the minima for a CAT IIIA approach?
50ft RA
RVR 200m
What are the minima for a CAT IIIB approach?
N/A
RVR 75m
What is and LTS CAT I approach?
LTS CAT I can be used on authorised runways which cannot support CAT II or CAT III operations.
Required RVR can be reduced below 550m on the basis that an autoland will be used
What are the minimum requirements for CAT I LTS?
Autoland is mandatory
CAT II required on FMA
LVPs must be in force
Suitability for CAT I LTS promulgated in LIDO
Minima for CAT I LTS published in the instrument approach chart
What is an OTS CAT II approach?
CAT II ILS approach where some or all of the elements of the precision approach or runway lighting system required for a CAT II approach are not available due to terrain or infrastructure constraints
If CAT IIIB minima are shown on LIDO, can you fly a CAT IIIA approach there?
Yes. Where a CAT IIIB is published, a CAT IIIA minima (DH50/R200) can be used by default if needed
(For example for a OEI approach)
Which approaches is the approach ban relevant for?
All approaches
What happens below 1000ft is you lose one of the required equipment which is not FMGC monitored?

What RVR is required for an auto roll out?
Mid-point 75m
Stop end 75m
What RVR is required for a manual roll out?
Mid-point 125m
Stop end 75m
From how far away can the ILS beam be used?
25nm within 10 degrees of centreline
17nm within 35 degrees of centreline
How would you classify mist?
Visibility affected by water droplets but >1000m
How would you classify haze?
Visibility affected by solid particles but >1000m
How would you classify fog?
Visibility <1000m
