Aircraft operators will not be permitted to conduct SA Category II instrument approach operations unless aerodrome control is in operation.

8.1.15.3         Runway Eligibility. An SA Category II approach procedure must not be designed for a runway unless:
(a)         the runway has, or is qualified for, a precision approach Category I ILS procedure; and
(b)         the aerodrome operator has given the designer information that the runway meets the requirements of the Manual of Standards (MOS) – Part 139 Aerodromes for SA Category II, Category II or Category III instrument approach operations.

Note: The specifications for a runway suitable for supporting SA Category II instrument approach operations can be found in Chapter 2 of the Manual of Standards (MOS) – Part 139 Aerodromes.

8.1.15.4         Precision Approach Facilities. The relevant aeronautical telecommunications service and radio navigation service provider must have given the designer information that the runway has precision approach facilities suitable for SA Category II operations.

8.1.15.5         Instrument Approach Procedure. The SA Category II DH minimum must be the higher of the following:
(a)         100 ft;
(b)         the calculated OCH.

8.1.15.6         The RA and DA minima must be calculated directly from the calculated DH value without rounding.

8.1.15.7         The SA Category II RVR minima must be the longest of the following:
(a)         for a runway with TDZ lights and no runway centreline lights — 400 m;
(b)         for a runway with no TDZ lights and no runway centreline lights — 450 m;
(c)          the distance derived in accordance with Table 8‑5, taking into account the type and length of the ALS, the aircraft category and the DH.

8.1.15.8         Instrument Approach Chart. On the instrument approach chart for SA Category II approach procedures, the SA Category II minima must be associated with a chart note stating 'Special aircrew and aircraft certification required' or similar words to that effect.

Section 8.2:   Lowest Safe Altitudes

8.2.1                   Lowest Safe Altitudes

8.2.1.1              ICAO Annex 11 Chap 2 outlines the requirement for the publication of Lowest Safe Altitudes (LSALT) and the criteria to be used for their determination. In particular, it states that the LSALT determined shall be at least 1,000 ft above the highest obstacle located within the area concerned.

8.2.1.2              The purpose of this standard is to outline the rules and parameters to be used for the calculation of LSALT
