Annex A — LVO training requirements
This is a sample training course syllabus as mentioned in clauses 1 and 3 of Schedule 2.
(a) Ground training
Ground training must cover at least the following subjects:
· general concepts and appropriate definitions (see ICAO Manual of All Weather Operations Doc 9365-AN/910)
· the importance of Alert Height; actions in the event of failures above and below the Alert Height; a knowledge of aircraft or ground equipment failures not protected by the Alert Height concept
· aerodrome visual aids, markings and lighting systems
· the meaning of the phrase “clear of runway”, with respect to runway exit light colours
· use and limitations of different types of RVR systems
· ILS characteristics, limitations and Class of Performance classification (see ICAO Annex 10, Attachment C, paragraph 2.14)
· the principles of obstacle clearance requirements for landing
· factors affecting the determination of landing minima
· effect of terrain profiles on radio altimeter readings at DH and on the autoland system
· characteristics of fog – homogenous and non-homogenous
· effects of cold temperature on the barometric altimeter reading for the glide slope check
· effects of precipitation, ice accretion, low level windshear and turbulence
· actions to be taken in the event of airborne or ground equipment failures
· reversionary minima
· an understanding of any special aircraft maintenance requirements for LVO equipment
· correct seating and eye position.
(b) Flight simulator training
The session should be approximately 3 hours for a captain paired with a first officer, or 4 hours for 2 paired captains. The session should be a stand-alone exercise conducted after all endorsement training has been completed. The simulator must be at least level C and type specific with correct visual modelling.
Some exercises should be conducted at maximum take-off weight (to provide a maximum split between V1 and VR) and maximum landing weight, both take-off and landing at approved (or applied for) RVR minima with up to maximum cross-wind and where possible a mix of day and night environments.
Training must include the following:
· normal operation with no failures
· visual cues required for landings, especially CAT II
· checks of satisfactory functioning of ground and aircraft equipment
· correct use of MEL and the effect of known unserviceabilities
· effects on minima caused by changes in the status of ground installations
· correct monitoring of automatic flight control systems and annunciators
· any reduced operating limitations
· maximum deviation allowed for glide slope and localizer
· actions to be taken in the event of failures or malfunctions of the following:
- ILS transmitter and ILS receiver(s)
- radio altimeter(s)
- autopilot(s) and autothrust system
- engine, electrical, hydraulic, flight control and instrumentation systems
- autoland system indicated by lack of expected FMA annunciations (flare, rollout)
· system failures pertinent to the aircraft type which would prevent an autoland when a failure occurs below the Alert Height
· engine-out autoland and engine-out missed approach
· loss of visibility during take-off and below the minima during approach
· pilot incapacitation during take-off and approach
· fail-passive automatic landing approach with further system failure below the minima.
Use of the aerodrome chart in following cleared taxi route to and from the runway and the terminal, identifying stop bars and CAT II and CAT III holding points and using all options to check line up on the correct runway.
There must be a minimum of 8 take-offs resulting in becoming airborne or in a RTO, covering the exercises below. Additional exercises should be conducted to cover operator requirements and the above training requirements.
Instructors should demonstrate in visual conditions the effectiveness of the localizer display or other lateral guidance equipment, as the aircraft deviates from the runway centreline.
Some suggested exercises are:
· normal take-offs (2) (RVR 200 m, cross-wind 15 knots – RVR in accordance with the take-off minima for the aircraft type, cross-wind 10 knots)
· engine failure near V1 (RTO) and engine failure at V1 (continue)
· loss of visibility at low speed (RTO) and after 100 knots (continue)
· pilot (PF) incapacitation
· deliberate runway centreline deviation.
Approach and landing, and go-around exercises
There must be a minimum of 8 approaches from at least 1 500 feet to either a landing or a go‑around. However, additional exercises should be conducted to cover operator requirements and the above training requirements.
Instructors should demonstrate in the simulator the approach (Calvert and ALSF-2) and runway lighting and various visual segments that would permit a landing relating to CAT II before students commence LV landing exercises.
Instructors must provide varying RVR reports to the crew during some of the simulator exercises to ensure a correct understanding of approach bans.
Some suggested exercises are:
· normal operations
· approaches resulting in missed approaches due to either lack of visual reference at DH or loss of visibility below DH
· aircraft and ground system failures
· loss of visibility above and below DH
· pilot (PF) incapacitation
· reversion to manual flight at or below CAT II DH to control flare, landing and rollout or missed approach
· reversion to higher minima
· fail passive CAT II or CAT III A approach with autopilot disconnect below minima
· engine failure at various stages of the approach and during the missed approach.
