Low Visibility Operations Flashcards
(39 cards)
What is the definition of Low Visibility Operations (LVO)?
LVO applies to takeoff operations in less than 400m RVR or approach and landing in less than 550m RVR.
What must the Commander ensure before commencing a Low Visibility Operation?
- The status of visual and non-visual facilities is sufficient
- Appropriate LVPs are in force
- Flight crew members are properly qualified
What is the RVR threshold for a Low Visibility Takeoff?
Less than 400 m RVR
What are the requirements for takeoff operations with any RVR element below 200 m?
All three RVRs must be at or above the appropriate minimum value.
What is the minimum RVR value for the mid-point on approach?
125 m or the TDZ value if that is less.
What conditions must be met to use 75 m for TDZ or mid-point on landing?
- ILS installation must support Cat III operations
- Aircraft equipment must be serviceable and operating in fail-operational mode
- LPVs must be in force
What does ‘relevant’ mean in the context of the stop-end RVR on landing?
‘Relevant’ refers to the part of the runway used during the high-speed phase of the landing down to a speed of approximately 60 kt.
If the crew deems the stop-end RVR to be relevant, what is the required RVR?
75 m
What is BA’s policy regarding approaches in minima lower than Cat I?
Must be followed by an autoland and auto-rollout if possible.
What is a downside of performing LVO training in the simulator?
Sim autolands tend to be perfect and exactly on the centreline, unlike real-world conditions.
Are classic circling approaches permitted in the USA?
No

What must crews have authorization for concerning manual landings?
BA does not have authorization for manual landings from LTS Cat I or Cat II approaches.

Sim autolands tend to be perfect and exactly on the centreline, unlike real-world conditions.
What should crews do after completing an autoland?
Fill in the AML (eLog) assiduously, including the tick-boxes.
Are classic circling approaches permitted in the USA?
No
