“Appendix 1 to OPS 1.455 Low Visibility Operations — Operating procedures

(a)

General. Low Visibility Operations include:

(1)

Manual take-off (with or without electronic guidance systems);

(2)

Auto-coupled approach to below DH, with manual flare, landing and roll-out;

(3)

Auto-coupled approach followed by auto-flare, auto landing and manual roll-out; and

(4)

Auto-coupled approach followed by auto-flare, auto landing and auto-roll-out, when the applicable RVR is less than 400 m.

Note 1: A hybrid system may be used with any of these modes of operations.

Note 2: Other forms of guidance systems or displays may be certificated and approved.

(b)

Procedures and Operating Instructions

(1)

The precise nature and scope of procedures and instructions given depend upon the airborne equipment used and the flight deck procedures followed. An operator must clearly define flight crew member duties during take-off, approach, flare, roll-out and missed approach in the Operations Manual. Particular emphasis must be placed on flight crew responsibilities during transition from non-visual conditions to visual conditions, and on the procedures to be used in deteriorating visibility or when failures occur. Special attention must be paid to the distribution of flight deck duties so as to ensure that the workload of the pilot making the decision to land or execute a missed approach enables him/her to devote himself/herself to supervision and the decision making process.

(2)

An operator must specify the detailed operating procedures and instructions in the Operations Manual. The instructions must be compatible with the limitations and mandatory procedures contained in the Aeroplane Flight Manual and cover the following items in particular:

(i)

Checks for the satisfactory functioning of the aeroplane equipment, both before departure and in flight;

(ii)

Effect on minima caused by changes in the status of the ground installations and airborne equipment;

(iii)

Procedures for the take-off, approach, flare, landing, roll-out and missed approach;

(iv)

Procedures to be followed in the event of failures, warnings and other non-normal situations;

(v)

The minimum visual reference required;

(vi)

The importance of correct seating and eye position;

(vii)

Action which may be necessary arising from a deterioration of the visual reference;

(viii)

Allocation of crew duties in the carrying out of the procedures according to subparagraphs (i) to (iv) and (vi) above, to allow the Commander to devote himself/herself mainly to supervision and decision making;

(ix)

The requirement for all height calls below 200 ft to be based on the radio altimeter and for one pilot to continue to monitor the aeroplane instruments until the landing is completed;

(x)

The requirement for the Localiser Sensitive Area to be protected;

(xi)

The use of information relating to wind velocity, wind shear, turbulence, runway contamination and use of multiple RVR assessments;

(xii)

Procedures to be used for practice approaches and landing on runways at which the full Category II or Category III aerodrome procedures are not in force;

(xiii)

Operating limitations resulting from airworthiness certification; and

(xiv)

Information on the maximum deviation allowed from the ILS glide path and/or localiser.
