requirements of the Manual of Standards (MOS) – Part 139 Aerodromes for SA Category I, SA Category II, Category II or Category III instrument approach operations.

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

8.1.14.4         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 I operations, including information about whether the precision approach aid is suitable for only HUD-equipped aircraft.

8.1.14.5         Instrument Approach Procedure. The approach procedure must be designed in accordance with the standards PANS‑OPS Category I or II criteria, using the Height loss/altimeter margin for radio altimeters.

8.1.14.6         The SA Category I DH minimum must be the higher of the following:
(a)         150 ft;
(b)         the calculated OCH.

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

8.1.14.8         The SA Category I RVR minima must be derived in accordance with Table 8‑4, taking into account the type and length of the ALS and the DH.

8.1.14.9         Instrument Approach Chart. On the instrument approach chart for SA Category I approach procedures:
(a)         the SA Category I minima must be associated with a chart note stating 'Special aircrew and aircraft certification required' or similar words to that effect; and
(b)         for procedures that are limited to HUD-only operations — a method must be used to clearly indicate this limitation.

8.1.15              Special Authorisation Category II Approach Procedures

8.1.15.1         Scope. Paragragh 8.1.15 provides the requirements for designing and publishing an SA Category II approach procedure with:
(a)         a DH of 100 ft or higher; and
(b)         a visibility minimum of 350 m or longer RVR.

Note: As detailed below, for an SA Category II approach procedure, the landing system and some ground facilities must meet all Category II requirements. However, Category II and III approach lighting, TDZ lighting and runway centreline lighting is not necessarily required.

8.1.15.2         Air Traffic Control. The aerodrome at which the runway is located must be a controlled aerodrome.
Note: 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
