Part 16APPROACH BAN FOR IFR FLIGHTS

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 operation.

(2) The pilot in command must not descend below 1 000 ft above the aerodrome elevation where a controlling zone RVR is reported by ATC as continually less than the RVR zone requirements.

Note Controlling zone RVR is defined in section 1.07. An RVR zone is controlling if a report is received from that zone, whether or not it is a required report.

(3) Subject to subsection (2), if, after passing 1 000 ft above the aerodrome elevation, a controlling zone RVR is reported by ATC as falling below the RVR zone requirements, the IAP may be continued.

(4) For subsections (2) and (3), the RVR zone requirements are as follows:

(a) a TDZ RVR report is always required, unless:

(i) the IAP is a CAT III instrument approach operation conducted with the use of an FO landing system and an FO or FP rollout system; and

(ii) the MID and END RVR zones are providing valid reports;

(b) other than for an SA CAT I instrument approach operation, a MID RVR report is required if the END RVR zone is not providing valid reports;

(c) other than for an SA CAT I instrument approach operation, an END RVR report is required if the MID RVR is not providing valid reports.

Note MID or END RVR reports are not required for SA CAT I instrument approach operations.

(d) for the TDZ RVR report — the RVR value shown on the instrument approach chart;

(e) for MID RVR zone report:
