AMC1 ADR.OPS.B.045(a)(2) Low-visibility procedures ED Decision 2022/013/R SUITABILITY OF RUNWAYS — APPROACH AND LANDING OPERATIONS (a) CAT II instrument approach operations may be conducted on a precision approach category II or III runway, using a CAT II instrument approach procedure. (b) CAT III instrument approach operations may be conducted on a precision approach category III runway, using a CAT III instrument approach procedure. (c) SA CAT I approach operations may be conducted in accordance with the following: (1) the runway is a precision approach category I runway and an obstacle free zone (OFZ) is established; (2) a CAT I instrument approach procedure that includes an OCH based on a radio altimeter is used; (3) where an ILS/MLS is used, it is not promulgated with any restrictions affecting its usability and is not offset from the extended runway centre line; (4) where a GBAS landing system (GLS) is used, it is not promulgated with any restrictions affecting its usability and should not be offset from the extended centre line; (5) the glide path angle is 3.0o; (6) the pre-threshold terrain is surveyed and either a precision approach terrain chart (ICAO Annex 4, Chapter 6) is published in the AIP or the required information is included in the aerodrome terrain and obstacle chart – ICAO (Electronic) (ICAO Annex 4, Chapter 5). (d) SA CAT II approach operations may only be conducted in accordance with the following: (1) the runway is a precision approach category I runway and an OFZ is established, and for operations with an RVR of less than 400 m, runway centre line lights are installed; (2) a CAT II instrument approach procedure is used; (3) where an ILS/MLS is used, it is not offset from the extended runway centre line and no restrictions affecting its usability are published in the AIP; (4) where a GLS is used, it is not offset from the extended runway centre line and no restrictions affecting its usability are published in the AIP; (4) where an ILS is used, it is certified to class II/D/2; (5) the pre-threshold terrain is surveyed and either a precision approach terrain chart (ICAO Annex 4, Chapter 6) has been published or the required information is included in the aerodrome terrain and obstacle chart – ICAO (Electronic) (ICAO Annex 4, Chapter 5).
