LVO's general questions (ppt sep '18) Flashcards
To memorize the details of the LVO ppt and support your day to day flying and sim details
1
Q
What is the difference between LVO’s and LVP’s?
A
- LVO’s are the airline’s low vis procedures
- LVP’s are the airport authority’s procedures
2
Q
What is the difference between CAT 3 DUAL and CAT IIIb?
A
- CAT 3 DUAL is the a/c’s capability and means it is fail-operational
- CAT IIIb is the facility that the airport offers to perform CAT IIIb approaches
To perform a CAT IIIb, the a/c needs to display CAT 3 DUAL on it’s FMA
3
Q
What should the a/c display on FMA for a CAT IIIa?
A
- CAT 3 DUAL or
- CAT 3 SINGLE
4
Q
What should the a/c display on FMA for a CAT II?
A
Either one of the following:
- CAT 3 DUAL
- CAT 3 SINGLE
- CAT 2
5
Q
What should the a/c display for a CAT I LTS?
A
Either one of the following:
- CAT 3 DUAL
- CAT 3 SINGLE
- CAT 2
An AUTOLAND from a CAT I LTS must be performed
6
Q
What is the lowest FMA required for an autoland?
A
CAT 2
7
Q
What does FAIL OPERATIONAL mean?
A
In the event of a failure BELOW ALERT HEIGHT, the approach, flare and landing can be completed automatically.
The automatic system will than operate as a FAIL PASSIVE system
8
Q
What does FAIL PASSIVE mean?
A
In the event of a failure there is no significant out-of-trim condition or deviation of flight path or attitude BUT the landing is NOT completed automatically.
The system assumes the pilot resumes control of the a/c after a failure
9
Q
What is the ALERT HEIGHT?
A
Specific RADIO ALT height Based on A/C specifics and it’s FAIL OPERATIONAL landing system.
In operational use, if a failure occured above the alert height in one of the required redundant operational systems of the aircraft, the approach would be discontinued and a go-around executed, unless reversion to a higher decision height is possible.
If a failure in one of the required redundant operational systems occurred below the alert height, it would be ignored and the approach continued.
10
Q
What do you do if you have a failure ABOVE the ALERT HEIGHT?
A
GO AROUND or revert to higher DH if possible and briefed
11
Q
What do you do if you have a failure BELOW the ALERT HEIGHT?
A
Continue the approach unless you have an AUTOLAND FAIL
12
Q
What is the EZY policy regarding executing CAT II/III/I LTS approaches?
A
- They have to be planned with AUTOLAND
- LVP’s MUST be in force
- FO’s are not permitted to carry out PRACTICE autoland as PF
- T/O minimum RVRs for departure are used from LIDO AOI
13
Q
When, in general, will ATC initiate LVP’s?
A
- Ceiling less or equal to 200 ft (BKN/OVC)
or
- RVR less or equal to 600 m
- Note: check local AOI for actual values*
14
Q
For Take Off, when is special training required?
A
- TO RVR <150m
(value for Category C aircraft)
15
Q
If operating to an LVP’s destination, what is the rule regarding “available aerodromes” during the flight?
A
OMB 5.1 FLIGHT PLANNING
ADEQUATE aerodromes must be available at any point along the planned route within a distance defined as 60 min flight time on one-engine inoperative cruise speed at standard temperature in still air. This distance is:
A319: 380 Nm
A320: 400 Nm
A321: 400 Nm
16
Q
What are the rules/considerations during taxi?
A
- No checklists while moving, only when standing still
- Brief taxi routing. Use headings for orientation
- If in doubt of position: STOP, inform ATC
- Lights may help for visibility
- NEVER go through a RED stop bar

53
What are your actions if you see that you have selected the incorrect ILS course when passing 350' on a CAT IIIB, NO DH?
- Revert to CAT II minima - Disengage AP at 50' at the latest
54
In which general cases, on a CAT IIIB DUAL, NO DH, but still ABOVE the AH, or on a CAT II/IIIa SINGLE below 1000' TDZE do you Go Around?
- Alpha Floor activation - AP OFF (Cavalry Charge) - Loss of CAT 3 (CLIC, CLIC, CLIC) - Amber Caution (Single Chime) - Engine Failure
55
If you have NO "FLARE" at 30', what are your options?
- If no visual references: GO AROUND - If sufficient visual references: disengage AP, manual land - In doubt: GO AROUND
56
What are your options when NWS fails when doing a CAT IIIB?
RVR check sufficient Minimum 50' RA Disengage AP on touchdown (No roll-out guidance)
57
What are your options when Antiskid fails when doing a CATIIIB?
Revert to CAT III SINGLE Disengage AP on touchdown (No roll-out guidance)
58
In which case can you still land if you have a RED AUTOLAND light?
If you have sufficient visual references to land
59
How many LVO approaches may be attempted in sequence?
2 attempts can be made Subject to significant wx improvement, emergency or non related GA and assured landing
60
Can you perform a practice CAT III landing on a CAT I ILS beam?
OM(B) states: Unless LVP's are reported active by ATIS, clearance to carry out a CAT II or CAT III approach must be requested from ATC, who will check the status of the ILS and lighting and protect the sensitive areas from incursion by aircraft or vehicles. Such an approach may NOT be undertaken until the clearance has been received. Basically, you can do a practice CAT III/II but you must request it with ATC and get the 'OK'
61
You loose visual contact on a CAT IIIa below 50' and decide to initiate the Go Around and you have ground contact. What are your considerations?
If the touchdown occurs after GA is engaged the AP remains engaged in that mode and ATHR remains in TOGA.
Grnd Spoilers and Autobrake are inhibited
62
In general, what are the 3 possible responses to the failure of any system, instrument or element during a LVO approach?
- CONTINUE the approach to the planned minima - REVERT to higher minima and proceed to a new DH (only above 1000' TDZE) - GO AROUND and reassess the capability
63
Below AH on a CAT III DUAL, NO DH, in which cases can you continue?
* Engine Failure
* Loss of one AP
64
Above 1000' TDZE a continuation after downgrading is permitted if:
- ECAM actions are completed - RVR is at least equal to the downgrade minima - Briefing is amended to include the procedure and DH for the downgraded approach - Decision to downgrade is completed before 1000' TDZE Note: switching of AP prior 1000' is always permitted
65
How is your 12 month recency maintained?
By carrying out 2 CAT II/III approach and landing procedures, one of which may be in the aircraft. In easyJet, all AWOPS recurrent training requirements are completed in the simulator
66
What are the planning factors for the departure alternate?
What is the maximum departure alternate distance for each type of aircraft?
* A SUITABLE aerodrome must be available when conditions at departure aerodrome prevent am immediate return to the departure aerodrome.
* The take-off alternate mjust be located within a trheshold distance based on OEI cruising speed (MCT) in ISA conditions based on the actual take-off weight/
* A landing with max T/O weight must be considered regarding lading mimima.
* 320 Nm for all types
67
When is a take-off alternate needed?
A take-off alternate is required when performance or meteorological conditions preclude a return to the departure aerodrome.
Meteorological conditions are suitable for return to the departure aerodrome when they are at or above the applicalbe minima for the instrument approach in use.
The weather reports or forecasts for the take-off alternate shall be at or above the applicable minima for the EXPECTED approach in use.
Any limitation related to one engine inoperative operation or dispatch under MEL conditioons shall be taken into account.
68
When is the approach ban point?
* 1000 ft airport elevation or;
* Into the final appraoch segement in case where the DA/H or MDA/H is more than 1000 ft above the aerodrome
69
What does the approach ban mean to the crew?
* You can continue appraoch past the approach ban point provided the TDZ RVR (and MID/STOP RVR if reported and relevant) are above minimum
* If the RVR deteriorates below minimum after you have passed the approach ban point, the approach may be continued to DA/H or MDA/H (in the case of CAT 3b NO DH - to land)
70
What is a LTS CAT 1 approach?
Lower Than Standard CAT 1 is a _Category 1 ILS approach_ in which the required RVR can be reduced _below 550 m_ on the basis that _AUTOLAND will_ be used
71
What are the LTS CAT 1 Additional Requirements?

72
What is the minimum braking action for an automatic roll out?
What are the associated minima?
* 5 - Good or better
* NO/75 m
73
What is an OTS CAT 2 approach?
An Other Than Standard (OTS) approach is a CAT 2 ILS approach where some or all of the elements of the precision approach or runway light system required for a standard CAT 2 approach are not available. The deficiency in lighting is offset by the use of Autoland.
74
What are the requirements to perform an OTS CAT 2 approach?
* Autoland is mandatory
* LVP's must be in force
* The required visual reference is the same as for CAT 2 (3 consecutive, 1 lateral)
