       (2) Subject to subsection (3), special alternate minima are only available for operations by aircraft with the following:
(a) at least 2 localiser and glideslope receiving systems;
(b) at least 2 VOR receiving systems;
(c) at least 1 of the following combinations of distance measuring systems:
 (i) 2 DME systems;
 (ii) 2 GNSS;
 (iii) 1 DME system and 1 GNSS.
       (3) Special alternate minima must not be used in any of the following circumstances:
(a) when an aerodrome control service is not provided;
(b) when an authorised weather forecast or authorised weather report is not available for the aerodrome;
(c) when ground equipment associated with the approach aid has been continuously unserviceable for more than 7 days and continues to be unserviceable.
Note   In the circumstance mentioned in paragraph (c), the non-availability of special alternate minima will be published in NOTAM.

8.09 Alternate minima — at foreign aerodromes
       (1) Subject to subsection (2), the alternate minima for an aerodrome outside Australian territory (the relevant aerodrome) are whichever 1 of the following provides the highest minima:
(a) the official alternate minima published in the State in which the aerodrome is located (the relevant State);
(b) the circling minima for the aerodrome, plus:
 (i) a cloud ceiling increment of 500 ft; and
 (ii) a visibility increment of 2 km;
(c) the landing minima of the relevant IAP, plus the following:
 (i) where the relevant State increments are published — those increments;
 (ii) where relevant State increments are not published, or if the availability or reliability of the approach aid is doubtful:
            (A) a cloud ceiling increment of 500 ft; and
            (B) a visibility increment of 2 km;
(d) if the determination of the relevant IAP is based entirely on the minimum altitudes of precision approach procedures:
 (i) a cloud ceiling of 400 ft; and
 (ii) a visibility of 1 600 m;
(e) if the determination of the relevant IAP is not based entirely on the minimum altitudes of precision approach procedures:
 (i) a cloud ceiling of 800 ft; and
 (ii) visibility of 3 000 m.
       (2) If:
(a) the aerodrome has straight-in procedures to a runway that are not suitable for the operation; and
(b) circling is permitted;
        then the alternate minima must not be lower than that derived from paragraph (1) (b).

CHAPTER 9 FLIGHT NOTIFICATIONS

9.01 Purpose
