At OMEGA, what example coordinations with APP do exist regarding LVP (CAT II/III operations)?
- departing acft commenced take-off roll before inbound has passed 6 NM final RWY 32
- sensitive area to be vacated before inbound has reached 2 NM final RWY 32
What's the name of a procedure during LVD?
Guided take-off
What must be secured during guided take-off?
- LOC sensitive area clear until departing acft has overflown antenna
- no subsequent take-off until preceeding departure has overflown LOC antenna
- sensitive area behind may be infringed (line-up, cross etc.)
Do all LVD involve guided take-offs?
No
LVD involving guided take-offs are not permitted if ...... ? (6)
- LOC out of CAT II/III tolerance
- LOC critical/sensitive area not vacated
- failure of ILS ground monitoring system
- failure of far-field monitor
- failure of LOC standby transmitter
- auxiliary power not working
What should you do afer aircraft has landed in CAT II/III to continue operations?
ask to report runway vacated (unless positively oserved on ASDE)
When shall the termination phase be initiated?
- when RVR reaches 550m or greater,
- vertical visibility and ceiling is 200ft or greater,
- condition are indicating sustained improvement
What is the minimum equipment required during CAT II operations?
1 LOC, 1 GP, 1 DME
What is the minimum equipment required during CAT III operations?
2 LOC, 2 GP, 2 DME
What is the minimum equipment required during LVD (guided take-offs only)?
2 LOC
Who has to be updated immediately about any deficiency or downgrading of operations? How should it be reported?
approach and flight crews
reported in terms of category of operations that ILS can support
What should be done with a longer downgrade?
more than 1 hour -> publish in NOTAM
Does a downgrade of operational status prohibit aircrafts to operate on higher status?
No, they can do it under their own responsibility
Any failure of secondary power supply will result in ...... ?
downgrading to CAT I ILS operations
LVD not available
For what reasons are operations during LVP downgraded?
- minimum required equipment not available
- aircraft or vehicle within any cirital area of ILS
- aircraft or vehicle within sensitive area of ILS, when arriving acft is less than 2 NM from rwy threshold
- aircraft or vehicle is within sensitive area of LOC, between position where acft will commence a LVD and LOC antenna
In what exception can an aircraft/vehicle be in the ILS sensitive area when arriving acft is closer than 2 NM?
Operations in low visibility shall not be considered downgraded if an obstructing aircraft or vehicle will vacate the sensitive area before the approaching aircraft passes a position 1 NM from touchdown.

What if an aircraft requests practice CAT II/III approach?
approve,
LVP need not be applied, departing or preceeding landing aircraft may disturb ILS signals
-> inform flight crew of this possibility: "Low Visibility Procedures not applied"
