Low Visibility Procedures Flashcards
LVP’s are instituted by who, and under what conditions?
By ATC.
Lowest RVR <600m, and/or
Cloud ceiling is ≤200ft
What is a low visibility take-off?
ANY take-off conducted in <400m visibility
What is a reduced visibility take-off?
Cat A, B or C = RVR < 150m
Cat D = RVR <200m
Who may conduct a take-off with a minimum visibility of 150m?
Any pilot with an IF rating, provided:
1.) LVP’s are in force
2.) The Operator has established procedures for low visibility operations
What is required in order to conduct a reduced visibility take-off?
1.) LVP’s in force
2.) HI CL 15m apart
3.) HI EL 60m apart
4.) 90m visual segment from the flight deck at the start of the take-off run
5.) Complete an approved course for LVO’s - specific to the operation and aircraft type
6.) Complete a check prior to conducting low visibility take-offs in RVR <150m (Cat D), or 225m if applicable
7.) Pass and maintain recurrent checks and recency requirements
What are the criteria for a Category II approach?
Precision approad and landing using ILS or MLS with:
100ft ≤ DA < 200ft, and
RVR ≥ 300m
What are the criteria for a Category III A and B approaches?
Category III A:
Using ILS or MLS with:
50ft ≤ DA < 100ft, and
RVR ≥ 200m
Category III B:
Using ILS or MLS with:
0ft ≤ DA <50ft, and
75m ≤ RVR < 200m
What is the purpose of instituting Low Visibility Procedures?
1.) Simplifies Category II and III operations
2.) Provides a Localiser Sensitive Area - 150m either side of runway centerline
- extends from the localiser to the beginning of the runway
- no person, vehicle or aircraft is allowed within the LSA when:
~ approaching aircraft is within 10nm of touchdown, until it has vacated the LSA
~ departing aircraft has commenced its take-off roll until it is airborne and past the localiser aerial
What is the RVR/visibility for:
1.) LVP’s to be instituted
2.) Low visibility take-off
3.) Reduced visibility take-off
1.) < 600m RVR
2.) <400m visibility
3.) < 150m RVR (Cat A, B, C aircraft) , <200m RVR (Cat D)
What must pilots do prior to commencing a Category II or III approach?
1.) Ensure the status of the lighting and approach facilities is sufficient (check NOTAMS)
2.) LVP’s are in force
3.) All Flight Deck Crew members are qualified in LVO’s
4.) Ensure there are no MEL items that would affect the flight performing LVO’s
What are the Operator’s Responsibilities during LVO’s?
1.) LVO’s must be approved
2.) Aircraft must be certified for decision heights below 200ft, or no decision height, and be equipped for such
3.) Have a system in place for recording approach or auto-land success and failure, and for monitoring overall safety
