at least 720 m from the runway threshold, which is either a precision approach CAT I lighting system or a precision approach CAT II and CAT III lighting system.

       3. The operating minima in each case are dictated by the available lighting facilities. Absence of an approach lighting system or a shorter approach lighting system will result in higher RVR minima. See the Manual of Standards (MOS) Part 173 – Standards Applicable to the Provision of Instrument Flight Procedure Design for specific details.

       (2) A runway at an aerodrome must not be nominated for an SA CAT II instrument approach operation unless:

(a) the aerodrome is a controlled aerodrome; and

(b) the runway meets the standards in this MOS for a precision approach runway CAT II, except for the following lighting facilities:

 (i) a precision approach CAT II and CAT III lighting system;

 (ii) runway centreline lighting;

 (iii) touchdown zone lighting; and

(c) the runway has electronic RVR equipment in the touchdown zone and at least 1 other zone of the runway; and

(d) the runway has a declared landing distance available of at least 1 830 m.

Notes

       1. A runway with an existing CAT II or CAT III precision approach procedure is automatically eligible for SA CAT II instrument approach operations.

       2. CASA recommends that, where possible, the runway should be equipped with an approach lighting system extending over a distance of at least 720 m from the runway threshold, which is either a precision approach CAT I lighting system or a precision approach CAT II and III lighting system.

       3. The operating minima in each case are dictated by the available lighting facilities. Absence of runway centreline lighting, touchdown zone lighting or an approach lighting system will result in higher RVR minima. Also, a shorter approach lighting system may result in higher operating minima. See the Manual of Standards (MOS) Part 173 – Standards Applicable to the Provision of Instrument Flight Procedure Design for specific details.

23.07 Facilities and procedures for conducting runway visibility assessments

        For runway visibility (RV) assessments, the aerodrome operator must:

(a) establish a system for using visibility markers or counting runway lights (or both) for assessing runway visibility; and

(b) establish and mark fixed locations from which assessments are to be conducted; and

Note   These locations should be near the threshold or midpoint of the runway, for example, the taxiway holding position for the taxiway adjoining the runway threshold, or at a point 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°
