adjacent to the runway threshold, from which the distance to visibility markers is known.

(c) if runway markers are to be used:

 (i) locate visibility markers to be representative of the runway conditions; and

 (ii) locate visibility markers within 10° of the runway centreline; and

 (iii) provide visibility markers that:

             (A) consist of dark objects of suitable dimension or lights of moderate intensity; and

             (B) meet the standards in this MOS for structural strength and frangibility; and

(d) produce a visibility markers chart that includes:

 (i) the visibility markers used to assess runway visibility, showing their distances in metres and bearings from the point of observation; and

 (ii) the identification of the day and night visibility markers in their proper positions by means of the designated symbols listed on the chart; and

 (iii) the clear identification of the point of observation; and

(e) if assessments are made by counting runway lights — produce a conversion chart based on the actual spacing of the runway lights; and

(f) include in the aerodrome manual:

 (i) the specific procedures for the conduct of runway visibility assessments at the aerodrome; and

 (ii) the names of persons authorised to conduct runway visibility assessments.

23.08 Appointed persons conducting runway visibility assessments

        An aerodrome operator must ensure that an appointed runway visibility assessor, both before appointment and at all times after appointment, has the following attributes and qualifications:

(a) a distant visual acuity of 6/12 or better in each eye separately, and 6/9 or better binocular (with or without correcting lenses);

(b) a certificate of proficiency in aeronautical radio telephony;

(c) the competence to operate on the manoeuvring area of the aerodrome;

(d) demonstrated competence in the following:

 (i) identifying the location of each point of observation;

 (ii) identifying the visibility markers for each point of observation;

 (iii) identifying the relevant runway edge lights for making a runway visibility assessment;

 (iv) using the conversion table and the visibility markers chart;

 (v) reporting a runway visibility assessment.

23.09 Conducting runway visibility assessments

       (1) Runway visibility assessments must be conducted without using any optical devices to enhance normal distance vision.

Note   The term "optical devices" does not include spectacles or contact lenses that the person usually wears for normal distance vision.

       (2) The appointed RV assessor conducting the runway visibility assessment must:

(a) not, at any time, make the observations through a window, unless it is otherwise impossible to make the observations; and

(b) make the assessment from a nominated observation point; and

(c) carry out the observation by:

 (i) establishing the farthest visible runway edge lights or visibility markers that can be seen and identified; and

 (ii) determining the distance, in metres to the nearest 50 m increment,
