slope indicator;
            (H) the TDZ or TDZ markings;
            (I) the TDZ lights;
            (J) the FATO or runway lights;
       Note   There are certain non-precision approach procedures that have a minimum flight visibility of 5 km, and where the geographical point of attaining the minimum altitude is more than 5 km from the visual references mentioned above. In these instances, noting that the minimum flight visibility is 5 km, if the requirements to conduct a visual approach procedure are met, effectively, the flight transitions from one conducting an IAP, to one conducting a visual approach at the minima.
(c) for a low-visibility operation, the following visual references for the intended runway must be continuously visible and identifiable to the pilot in command:
           (i) for a CAT III approach using an FO landing system where use of a DH is prescribed — at least 1 centreline light;
           (ii) for a CAT III approach utilising an FP landing system — at least 3 consecutive longitudinally-aligned lights;
           (iii) for a CAT III approach utilising an FO hybrid landing system — at least 3 consecutive longitudinally-aligned lights;
           (iv) for any other low-visibility operation:
            (A) at least 3 consecutive longitudinally-aligned lights; and
            (B) unless the approach is conducted using a HUD — a lateral element of lighting in the form of an approach lighting crossbar, a landing threshold light, or a barrette of TDZ lights.
       (3) For paragraph (2) (c), consecutive longitudinally-aligned lights means any of the following:
(a) centreline lights of the approach lighting system;
(b) the TDZ lights;
(c) runway centreline lighting;
(d) runway edge lights;
(e) a combination of the lights mentioned in paragraphs (a) to (d).

CHAPTER 16 APPROACH BAN FOR IFR FLIGHTS

16.01 Purpose
       (1) For subregulation 91.310 (1), this Chapter prescribes circumstances in which an aircraft flown under the IFR must not make an approach to land at an aerodrome.
       (2) This Chapter applies to an aircraft conducting an IAP at an aerodrome:
(a) that has an air traffic control service in operation; and
(b) for which RVR reports are available for IAPs to the relevant runway.

16.02 Approach ban — other than low-visibility operations
       (1) This section applies to an operation that is not a low-visibility operation.
       (2) The pilot in command must not descend below 1 000 ft above the aerodrome elevation where the TDZ RVR is reported by ATC as continually less than the landing minima for the IAP.
       (3) Despite subsection (2), if, after passing 1 000 ft above the aerodrome elevation, the TDZ RVR is reported by ATC as falling below the landing minima, the approach may be continued.

16.03 Approach ban — low-visibility operations
       (1) This section applies to an operation that is a low-visibility
