Operator Obligations
An Operator must establish procedures and instructions to be used for Low Visibility Take-Off and Category II and III operations.
These procedures must be included in the Operations Manual with approval by the Authority.
The procedures shall contain the duties of flight crew members during taxiing, take-off, approach, flare, landing, roll-out, and missed approach as appropriate.
Particular emphasis must be placed on flight crew responsibilities during the transition from non-visual conditions to visual conditions, and on the procedures to be used in deteriorating visibility or when failures occur.
The instructions in the operations manual must be compatible with procedures in the Aeroplane Flight Manual and cover the following items in particular:
I/ Checks for the satisfactory functioning of the airplane 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 references.
VIII/ Allocation of crew duties to allow the Commander to devote himself 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 airplane 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.
XIV/ Information on the maximum deviation allowed from the ILS glide path and/or localizer.
Training Requirements
The Operator is responsible for training crews in low-visibility operations.
They must be simulator-checked and qualified for each operation.
This training is type-specific and all flight crew require qualification.
Equipment Status
The Operations Manual must list the minimum equipment that has to be serviceable at the start of a Low Visibility Take-off or a Category II or III approach.
The aerodrome must be approved for Cat II or III operations by its authority and the Operator must establish that low visibility procedures are in place.
Note - It is up to the commander to satisfy himself that the airplane, the crew, and the airport all conform to the requirements before conducting low visibility operations. (If anyone does not, then low visibility operations are not permitted.)
Validation & Oversight
A suitable system for recording approach and/or automatic landing success and failure must be established and maintained to monitor the overall safety of the operation.
